An Overview Of EPOS Systems And Their Many Advantages

By David DD Duncan

Electronic Point of Sale (EPOS) software is often found in most retail and wholesale businesses. EPOS systems are designed to help in improving business performance and productivity. When running a shop, investing for an EPOS is really an ideal way to do things. An EPOS can really help your retailing business in many ways. It enables your information to be stored and even accesed to the advantage of your business. The system also provides accurate and reliable insights about the status of the business through automated monitoring of business processes.

EPOS systems are often found at a business' checkout area but can also be linked into some other terminals related to the business. As a matter of fact, the system can also be linked to a running website. When you link EPOS to the system of your business website, your customers will then be provided with updated and real time information regarding with your stock via automatic stock control. Also, links to other business terminals within your shop will result to a much greater control of your company as a whole.

EPOS can be a great way of storing all sales information of a business. Through using the automated system, the system can be able to detect the demand on different products. The information can then be used in reducing your inventory. If you found out that some of your products do not sell well with a particular time frame, you can place these products on alternate websites like eBay. This can be done when you are using EPOS systems to monitor your sales on different products since it can be manipulated through this automated system. The EPOS software can also let the users print receipts and voucher, and even send reliable information regarding important transactions to your suppliers and customers. That way, the system can help in improving business reliability and efficiency. The EPOS software is also easy to use as it is designed from a user's perspective. It can help in calculating where the profit lies. It can also help the business through identifying customer habits of the customers and it keeps track on the movement of the stock. This also means that all members of the company can reduce or increase the order of the products from your suppliers according the demand as well as profit gained from the products.

Other Benefits Of EPOS Systems

EPOS software provides the suppliers with purchasing data and tracking sales. It gives the suppliers the right information especially in customer purchasing habits. Your marketing also helps the system factor your own order demands.

You can also integrate data from your EPOS systems with data from other handheld scanners. This means that you can be able to track products with barcodes right from your suppliers up to the store's final point of sale. Because of that, you can then be able to identify and compare different supplier's performances as well as their efficiency in times of delivery. After you have assessed different suppliers, you can better improve your business based on the results.

Different Types Of Servers Available In The Market Today

By Pooja M Shah

A server in non-technical language is a computer system that conducts or hosts several computer services in order to ensure that computers in a network or the internet can communicate in turn making two or more people on different computers communicate effectively. There are several types of servers and they are classified depending on the kind of work they do, they are

web servers
Mail severs
application servers
File servers
Proxy servers
Real-time servers

Proxy Servers

These servers are normally found between a web browser and another server normally outside of the room normally on the internet where it filters and helps to fulfill the requests or queries of the initiator as well as sharing connections. It acts as a gateway by receiving requests and relaying them to the other server by simplifying it such that the other server works in the least time therefore improving the performance of the server.

Web Servers

A web server is a server that enables all the data in a website to be received by a browser. It does this by communicating to a disk that has the specific data the client is looking for; getting this information from a disk to a web page cannot be done without this kind of server. This transfer is made possible by the use of programs called protocols; in this case the protocol responsible if the hypertext transfer protocol.

Real-time Servers

These servers are the servers that make chatting possible; they enable the relay of data at the touch of a button. They are also responsible for services such as instant messaging and they have the capacity to carry many such messages or chats at the same time and deliver them on time, instantly. These servers are constantly at work and have been employed by many mobile applications as well as computer and internet programs.

File Transfer Protocol Servers

FTP is probably the oldest protocol in the internet world, it is the protocol that enables the secure transfer of files across the internet form one webpage to another, one email to another and the like. It is such protocols that led to the design and coding of protocols such as HTTP and languages such as HTML and XHTML.

Open Source Servers

Open source servers embrace the freedom of all other open source software and are a critical part in enabling the exchange of data in all information technology infrastructures but are dominantly found in open source operating systems such as Apache and Linux.

Cloud servers

These servers are the newest in the market and boast the ability to do many tasks including supervision of other servers and storing data. They are virtual and therefore found on the web and help, to keep the integrity of online data for most websites now because they save space and money.

Cloud Servers Vs Dedicated Servers

By Pooja M Shah

Cloud computing is fast becoming the best thing to ever happen in the computer world; and a feat that is not so easy in a word that is dominated by daily change of updates, and software development. Cloud server hosting is a new way of backing up data where the client is setup with a virtual account where he can save and manage his entire data network without the need of a physical server.

The client can be able to save the data, change it and access it because only he has the password to his cloud network.

The traditional dedicated server was a prerequisite for people who needed internet hosting, however that has all changed and here is why

Cloud hosting is cheaper

Cloud hosting does not require the hardware that comes with dedicated servers; this is because they have smaller hosting models that perform and make sure better security; all at a cheap price, which makes many companies, prefer the use of such technology.

Cloud servers offer better Security

When backing up data, the major consideration is the security of the data, and then you can think of other issues such as cost and what have you. Cloud servers also known as VPS accounts are designed such that they do not interact with each other further frustrating hacking efforts and offer an opportunity to build your server firewall in our own design or customization.

VPS hosting offers faster services

In business, and now in the current market, time is a commodity that has found so much value. That said nobody wants to sit in front of their computer waiting for a response from their server to respond or reply. Cloud services are configured such that they use the shortest time to relay the data they contain after receiving such a request from the client. They also do not need physical connections that can be time wasting and error strewn.

Cloud servers give more capability

This is in terms of control, if the client would like to supervise how his data is backed up, he can do so using cloud hosting services whose infrastructure has been simplified to allow anyone with elementary computer training to understand how to use it and manipulate it as long as they have the right passwords. You can also customize your cloud by installing your own software and hardware.

Could servers have better performance

The space on cloud computers are well-regulated, this means you get resources as you need them, therefore, avoiding the occurrence of bigger companies using up most of the cloud space and leaving none for the smaller one. The resources are also expandable by the service provider and are usually big enough to hold a huge amount of data.

Types of Internet Protocols

By Pooja M Shah

Internet protocols are different types of Internet connections for different things on the World Wide Web. They help in the retrieval, transfer, exchange and downloading of files, or information on the Internet. Without these protocols, the Internet would not be, as we know it today because many browsers would not work without the permission of these protocols. There are different types of Internet protocols each serving a different purpose. These are

1. Electronic mail transfer protocol

This protocol allows for the use and availability of email, it is what the post office is to letters. It consists of three other protocols that make transfer and access of the emails; these are the simple mail transfer protocol (SMTP), the Internet message access protocol (IMAP) and the Post office protocol 3 (POP3). The IMAP and POP3 are the protocols that allow you to receive emails while the SMTP is used when sending emails hence the "transfer" part. These three protocols are embedded in most web browsers.

2. NNTP

This protocol is used as a server of Usenet forums that are dedicated to organizational forums that have different topics of discussion. These forums are broken down to topics, subjects or genres. This protocol offers a platform where they can be discussed and views exchanged.

3. File retrieval protocols

As the name suggest, this protocols allow you to retrieve information from the Internet to the computer or from the computer to the Internet. Though it is now redundant, you could use it to view the files if you knew the name of the file or properties about it.

4. FTP (File Transfer Protocol)

The file transfer protocol is a protocol that allows you to move one file from your computer to another on the Internet. You can also log on to a computer remotely and access the files in it with authority from the other computer. This protocol also allows downloading of applications from the Internet.

5. Telnet

This protocol allows you to access a remote computer. It works in such a way you are able to view files on the other computer as if you were there by telneting into a specific file or application in the remote computer and you are able to see what is on the computer. It is a darling with many hackers.

6. Gopher

Gopher allows you to know a few details about a file, application or a description of a file before you download it. These files could be on a remote computer and gopher allows you to view these files in a hierarchical manner and delivers them to you when you search them on the server.

7. HTTP

This protocol allows web servers to show and display all the aspects of a webpage. They form the first part of every web address such that all web pages or website. This protocol makes it easy for the file transfer protocol to do its work.

Predicting Product Release Dates Using Agile

By Jeff M Nall

If you can't reliably set a project deadline based on hours of work, how do you do it?

Everything hinges around User Stories and the relative effort the team assigns to each. The Product Owner solicits users for the features they want in this new product and captures this information in the form of User Stories. During Sprint Planning (and backlog grooming-another topic) the team gives their best "Snap" judgement of how much effort it will take to complete a story. Effort is reflected in many ways but most commonly using a Fibonacci number sequence (1,2,3,5,8,13,21,44,65, etc). A low effort Story is a 1, increasing in difficulty the larger the number. The Product Owner considers the effort involved along with how valuable functionality is to the customer base and prioritizes the User Stories accordingly. The highest value, lowest effort stories tending to be first in the priority list ending with the lowest value, highest difficulty stories at the bottom.

An Agile team determines it's commitment for a Sprint based on a history of how many Effort points a they complete on average in a Sprint. Let's say in the last Sprint the team completed three user stories. The team came to a consensus that each of the three user stories had effort values of 3,13, 1 and 5. The sum of these numbers is called Velocity.

The team has a Velocity of 22.

With newly formed teams this Velocity number will vary wildly from sprint-to-sprint. Established, well functioning teams will see this number stabilize and increase over time. I'm leaving off quite a bit of info on backlog grooming, technical debt and making adjustments on the fly, but this 30,000 foot view hits the highlights. I'll cover Velocity points in detail in a future post because while they're simple, I've seen them misused as ratios to hours worked and generally something other than the educated "snap" team judgement they're meant to be.

So how do you predict the release date? You do it basically the same way a team decides how many user stories it can commit to completing in a Sprint. At this level, add up the effort points for all of the user stories that comprise Version 1.0 of your product, divide it by the amount of effort points the agile team is averaging in a (typically two week) sprint and look at a calender. You'll get a decent ball park estimate of when the product will be finished. Let's say you've added up the effort points of all of the user stories in Version 1.0 and you've come up with 100. Your agile team is averaging 20 points in a two week sprint. You can plan on about 10 weeks for a rough project completion time.

You can still generally plan your releases in Agile just like you do in any other development model, you just have to learn to rely on different indicators, that's all. The big difference is Agile acknowledges the unknown while other methods try to hide it.

The Hotrodder's Triangle

By Jeff M Nall

In the automotive performance world there's a saying called "Fast, durable, cheap: Choose any two." The same saying either originated or found it's way into (more likely) the project management world and is commonly referred to there as the Project Management Triangle.

The point is you can't have all three things at the same time. Moving toward any two traits shorts you on the other.

If you're in the software industry, you're familiar with deadlines. You've made a commitment to the customer to have functionality to them by a certain date and now you have to deliver. Compounding the problem is the on-boarding time of new developers to devote to solving an issue because you can't expect the new guy/girl to be fluent out of the gate; there's ramp-up time involved to learning the nuts & bolts of the project. If you follow Brooke's Law (from the excellent book The Mythical Man-Month), time is actually added to the scope of the project when you bring on new developers late in the game to help out.

Paradoxically, the more programmers you devote to a late coding project, the tendency is for that project to become even later.

If you want to deliver the features promised faster, the only way you can do it is to skimp on the remaining side of the triangle: Quality.

What do you do? Transparency, always. If you've made a mistake your customer is going to appreciate the candid insight you give them into the reasons you don't want them using your product yet. You never have a second chance to make a first impression; that bad code you give to the customer will make them forever suspicious of future releases you make (translation: they don't value your product as much). Apple is a great example of a company that (up until the Maps fiasco) thoroughly exercises their products to the point where everyone is excited to upgrade. With respect to my friends at Microsoft, it's been a long time since I applied a service pack without planning on having issues because I've been burned too many times over the years. (Don't get me wrong here--I think Apple is to office productivity what double bladed skates are to an ice rink.)

Agile teams operate on a Definition of Done. If the code does not meet that DoD, it doesn't leave the room. DoDs generally contain testing and documentation standards, code reviews, demos and anything else the team can think of to preclude bugs finding their way into their customer's hands. The DoD is essentially a contract the team has with itself; if the work done during the sprint does not meet the criteria established in the DoD, the work is not done. The DoD serves as guard against doing virtually the only thing you can to deliver a late project on time: sacrifice quality.

Three Dimensional (3D) Printing At A Glance

By Rajot Chakraborty

In the beginning

In the mid-80s when the first machines for 3D printing began to circulate, few were willing to bet that the technology had a chance to drive a real revolution in the field of manufacturing. At the time the only available technique was stereo lithography, which utilized print layers of photopolymers modeled through the use of ultraviolet light and gradually superimposed to form more or less faithful reproduction of a three-dimensional object. It was a slow and expensive process (a machine could cost as much $ 500K) and therefore was unattractive for large-scale application. Almost thirty years later, the situation has drastically changed.

3D Printing Today

The cost of machinery over the years has literally collapsed, to the point that these days many companies exploit 3D printing to build three-dimensional prototypes of plastic material without having to activate an entire production process ad hoc. But it is only in recent years that the prices of machinery for 3D printing have decreased dramatically, making it possible for the common man to use 3D printing technology. Suffice it to say that there are companies that have already sold small 3D printers whose price do not exceed one thousand euro (some even offer it in less than 500 euro).

3D printing Production Techniques

Of course, the basic concept of 3D printing is interesting: build a three-dimensional model on your computer and input commands, which will order the printer to use the 3D model and forge a true representation of the model. Most 3D printers use a production technique known as additive manufacturing - the desired object is modeled printing a layer at a time and superimposing it to those layers which are already printed. This can be done in several ways. 3D printers using laser sintering method create the object by heating the powder metal or the thermoplastic.

In Fused Deposition method, a heated nozzle is used that melts the material, which lies three-dimensionally so as to reproduce the 3D model displayed on the computer screen. There are other techniques used mainly in industrial environments, such as the Laminated Object method, which involves stacking thin layers of material, which are engraved by laser from time to time. There are several methods which can be used in 3D printing, for reproducing the image of an object, very realistically. Different organizations and industries use the method which is best suited to meet all the needs of their business.

Escape the Data Deluge: Rise Above the Floods

By Darren John Williams

Much like your favourite threadbare blanket from your toddler years or that pile of magazines collecting up slowly in your drawer, data is just as likely to be hoarded. Whilst data means information, this deluge is particularly problematic when it comes to the field of data analytics. However, with the right techniques, you can use this overflow to your advantage.

Back in 2010, Google Chairman Eric Schmidt made the startling statement that from the dawning of time up until 2003, 5 exabytes of online data had been produced. Fast forward to 2010, and we produced this same amount of data every day! With the rate of data production mounting by the week, you can bet that this figure is even greater now.

Every time you upload that arty, sepia photo to Instagram, you are contributing to this deluge. Your photo is one of the 5 million photos that are uploaded onto the site daily, an unbelievable 1852000000 photos a year! But don't be too hard on yourself. Social networking sites, smartphones and blogs are all perpetrators in this deluge. Now that you can create and share data 24 hours a day, whether you're on the train or at work (don't worry, we won't tell), the problem is being made even worse.

Developers are driving towards a creation of more powerful servers to fulfil this demand, however with this, the data upload limit is also increased. This means a circle of increasing data, increasing capacity for data and (you guessed it... ) even more data. We are constantly striving beyond our means; a clear example of the old 'eyes bigger than your belly' situation. With the recent debut of 4G into the smartphone market, it's obvious that we are on the path to limitless speeds, storage and processing power for our networked devices. It would only be fitting that we also had powerful servers capable of uploading and processing this vast quantity of data as well.

The circle of increasing data shows no sign of subsiding any time soon and, therefore, it would be easy to feel as if you were drowning in this constant flow. However, whilst this data deluge is worrying, it can be used to your advantage. Data means information and, therefore a vast pool of knowledge to take advantage of. All you need is greater accessibility and transparency to data so that it is more easily available for you.

Whether you're doing clinical research or a census investigation, Document Capture Co. (http://www.documentcapture.co.uk/) has the right expertise to be able to help you tackle the deluge. Contact us for a meeting and we can have a no-obligation workshop to see how we can assist your business to rise up above the data deluge.

Talking Through An RJ11 Cable

By Jason Smythson

It is easy to dismiss an RJ11 cable as simply a phone cable and be done with it. But it is important to remember that if you want to maximize your home Internet experience, then you need to pay attention to every single aspect of it. If you use the Internet service offered by your phone company, then you probably have DSL or ADSL Internet service. This is a service that is provided through the same jack that is also used for your phone service. The phone company will provide you with a splitter and adapter that will allow you to have your phone and DSL service through the same jack. One of the cables will be an RJ11 ADSL modem cable.

The thing that most people neglect is the connection that runs from the phone jack to the Internet modem or router. The signal that is not filtered is the one the runs to your Internet router, and that signal needs to be clear and consistent if you want to have a strong Internet connection. If the connection from the splitter is loose or the cable you are using is unable to maintain the bandwidth you are supposed to get, then you will not be able to get the most out of your Internet service.

The best solution is to invest in a high quality splitter that has good contacts and a solid case. This will insure that the RJ11 cables you have plugged into the splitter remain in place, and it also insures that all of the connections in the splitter and to the phone jack are clear as well. The other piece you need to invest in is a quality RJ11 cable that is specifically designed to carry a DSL or ADSL signal. This is especially important if your router is more than 10 feet from your device. The longer that the signal has to travel, the more important it is to have a quality cable.

Most people are extremely familiar with an RJ11 cable connection as they see them every day on telephones and modems. Most people confuse the RJ45 networking connection with the RJ11 connection, but the RJ45 plug is larger and serves a much different purpose.

Your Internet connection begins at the wall jack and not the router. The connection from the wall jack to the router must be a high quality cable if you want to get the most from your modem. That is why it is extremely important to invest in a high quality RJ11 cable for your Internet modem or router.
