Project structure of web services
When you heard about Project Structure of Web Service, what is the first thing you get in your mind about the ideal structure? With many companies using the internet nowadays, the world has gotten a great number of web services. Some developers create their services with the particular language and technology such as Python, while other developers use other languages and technologies, including SOAP, XML, Java, REST, WebSphere, JSON, Jersey, JBoss, Django, and other similar things. There are too many of them that even need quite a long time for me to create a complete list of them.
Despite the great varieties of the languages and technologies as well, there is one important thing that commonly becomes the red line amid the various web-service projects. For years, web-service experts have entered the long and hot debate about how they should define and structure Web Service Project Structure. Well, personally, I never like when a simple discussion goes long, especially when web services are not a new thing on the internet world. For a long time, software engineers and web developers have worked together in building web services. The good news is; they not only complete the development stage, but also, they have provided us almost all answers we need to know about web services.
The first basic information about project structure of web service is it contains two important players: client and server. Client will make a request, submit it, get a response upon the request, and finally ‘asks’ one or more application to do appropriate service relevant to the request.
At the other side, we also have a server. A server stands as processing unit which will take any requesting client submitted, process it, and return the appropriate response.
Due to their different roles, it is clear that having different stances of both client and server is mandatory if we look for useful web service. Furthermore, it is a necessary step we should apply to immediately deploying the server artifact onto an application server. Of course, if we want the server to show optimum performance, the server should stand as the independent project.
You must remember one universal fact that happens in web-service world: many companies fail to avoid the temptation in putting both characters at different posts. This is the strongest temptation because you will face two important options at once. First, you must think the most basic rule in economy: how to increase your profit while you should reduce the operation cost as minimum as possible. At the second side, you must think about how to improve the effectiveness of all resources you get, including the web services. You may think about getting the middle point as the best solution, but I remind you one thing: it is keeping both aspects as different aspects or complete failure. In the business, it is all about commitment. You can only reach your success if you commit yourself in optimizing all resources. Do not get into the profit temptation. You may need to wait longer than other companies when you choose to differing client and server, but believe me one crucial thing: you have done everything right if you separate both of them.
The second reason we can conclude from long debate on web-service project structure is about the constants, exceptions, and models we get. Well, this question is a quite fair one if you have an intention to have the ability in sharing your files with both server and client you get. For example, if you get the model objects, your server will need to populate the requests with similar information and then return them to the client. At the another side, your client will also need to receive the same type of the object and then pass the information to the specific application they believe will become handy for this purpose. The similar case happens to constants, exceptions, and other similar objects. The good news about those objects is we can solve them with the little help from third-party project.
In addition to standard projects, companies do through their web-server project structure; there are some additional projects companies commonly use to break any dependency that may occur between client and server even though you may have separated them. In fact, you may have started to think about whether to use both projects or not in the real life, but that will be the moment when you will soon realize you need personal preference to kick in the project. As the alternative option, you may also think about whether to put all files you think both clients and servers will need in other possible projects in the future. Then, you continue with making another common project which focuses in dependency issue of both aspects. Well, there is always a good thing about something, even though when theories say the contrary. The good thing we can learn about the common project between client and server is it will not create major differences once you have completed the initial development.
