With the advent of the internet a person appear more and more features. Nowhe can find relevant information quickly and in a timely manner without going for itin the library and disappearing between the shelves. It can perform a variety ofshopping at any of the country without a physical presence in the office. It cantransfer money from one account from any country to any other country justpressing the buttons of computer. Internet is fast and read into our lives and makesit much more convenient. That is why the development of Web applications isclaimed and relevant in our days.Every year there are new technologies to simplify programming and to createmore and more advanced features to developers. The end-user does not know all ofthis, but gets comfortable interface and flexible opportunities for the commission ofcertain acts.This project is not commercial it’s just a case study, based on some newtechnologies that have been studied during my education, along with the fact theinterplay between different software applications together. In ordinary life, such aproject is a very serious and difficult and written group of programmers. It isdivided into parts and each part is realized by different people. Conventionally, theproject can be divided into several parts, such as: database, design of site, making-up design, client and administrative applications.Before creating database system it is necessary to analyze some data, sort datahave to be used in the application. In this case it should be data about books,authors, publishing houses, purchasing through the internet, clients and other object.The next step of creating of database system is making entity-relationship modelbased on the data analyze. Some tables, attributes and relationships should bedefined at that moment. And only after then create relationship model of the database system, where every table is defined by attributes, where every attributehas a type and all relationship is implemented.Client-side application is a program that runs on client computer when heopens the web-browser. Using this application he can find books, add it to his cart,login and register in the shop and make another actions.Administrative-side application has to be created to manage this shop. It isnecessary for somebody to rule it, to add and delete some information, for examplebooks, users, orders, etc. Also the administrator has to keep in contact with clientsand support the shop.Finally, the realization for software systems shows the working example ofinternet shop.
