Programming Representational State Transfer (rest)

Programming Representational State Transfer (rest)

REST (representational state transfer) is a process for getting information content from a Web site by reading a designated Web page that contains an XML (Extensible Markup Language) file that describes and includes the feasible content. For example, REST could be used by an online publisher to make syndicated content available. Periodically, the publisher would prepare and activate a Web page that included content and XML statements that described the content. Subscribers would need only to know the URL (Uniform Resource Locator) for the page where the XML file was located, read it with a Web browser, interpret the content data using the XML information, and reformat and use it appropriately (perhaps in some form of online publication).

Now question is that why doesn't the REST programming section include any code? It is largely because REST is more about a mindset rather than code, more about design than implementation.It may look simple, but there are few vital points to keep in mind while developing applications in the REST style. Think about the business problem in respect of resource manipulation rather than Application programming interface design. Enabling web services requires making data available for use by applications without knowing ahead of time exactly how that data will be used. Start by modeling the persistent resources that is to be exposed.

There must have a single, unambiguous, authoritative identity within a system in order to identify all the conceptual entities that the system exposes as resources and to assign a unique URL to each of them. In case of temporary resource you should be very careful if you plan to use them only as a temporary resource.

Publicly exposed resources should be sorted out that are immutable by the client and those are mutable. Putting and deleting should be used in appropriate manner. Proper methods should be implemented that will allow both sender and receiver to make the absolute minimum of assumptions as to the other's state.Single logical operation should not be implemented when there are multiple requests. Applications that need to be expects, accepts and returns should be properly documented. A good specification of the representational schema of both mutable and immutable resources with a formal mechanism should be there (for example, XML Schema, DTD, Schematron, or RelaxNG).

There should be a proper description and documentation of the resources that can be accessed by using a "gradual unfolding methodology" to expose data for clients. Proper linking to other related resources in every representation to enable clients to drill down for more information should be there.You should know how to use the software to setup a server that can do content negotiation, authentication, authorization, compression, caching, vacuuming and house cleaning. A proper abstractions should be there so the implementation can be carried out in a good way. If there is abstractions then it can survive the storm of change from different implementations and new technologies.

Estate Agency Displays ? Making Your Business Stand Out from the Rest!

Estate Agency Displays ? Making Your Business Stand Out from the Rest!

Let's face it; the global recession has had a significant impact on all of us in different ways. Nobody thought that the recession was going to be an easy ride, however, it has proved more crippling that we ever expected. With the Government's new initiatives already starting to take shape and come into force, we're all facing tough times ahead.

Although the global recession has been a damning time for all, it has however brought about many new opportunities. Look at the property market for example – prices have significantly dropped making it easier for first-time buyers to get onto the property ladder. Prices are still extremely low and it looks like it will be even longer than anticipated for house prices to start rising significantly again.

If your job entails anything to do with the property market, you will be fully aware of what changes have occurred since the UK went into recession. As you will probably agree, estate agents are currently being overloaded with work because of the significant amount of people looking to sell their homes. Although this may be viewed as unfortunate due to the fact that people are selling their homes in order to free up capital, this is clearly working in favour of estate agents. It is therefore vitally important at this present time for estate agents to be pro-active when it comes to marketing.

Estate agents have greatly changed their practices over recent years, many of which are utilising the power of the Internet to sell properties; however, traditional methods of marketing are still as important. As you will have probably already noticed, the number of estate agents who have estate agency displays in their windows is increasing.

Unlike traditional A4 pieces of paper stuck to the window with Blu-Tack, estate agency displays are ideal for drawing attention to properties. Estate agency displays are rotating electronic displays which are incredibly easy to change and have a double effect; firstly they stop people as they walk past, and secondly they entice people to enquire about properties which they are interested in.
