The goal is to develop a system model necessary for structuring the subject area, decomposing the functions performed by a web application; formalize the design methods, determine the general method of synthesizing Internet-oriented information systems. The main part of the development is the creation of a model, which components will be the objects of the domain, while attention should be paid to balance - the flexibility of the model and the development costs, taking into account the possibility of reuse. Too flexible components will have too many properties and will be difficult to customize adjust. On the contrary, models that implement too particular situation will be useless in terms of reuse, and, perhaps, the cost of its implementation will not make sense. For a more complete understanding of the functions and requirements for data processing, it is necessary to identify the main objects of the domain, information flows, logical connections, as well as rules and restrictions when working with data. The result of building a model should be a DBMS-independent data schema (metadata) corresponding to the internal data structure of the Web application, focused on the implementation of the required functions when interfacing with the user.
