In the system specification the structure of the database, the configurable attributes and process management are detailed, as well as the supported functions.

Then, the details of the implementation follows, briefly the chosen technologies and the development environment are presented. A description of the design and implementation for each layer is also included, and it provides an insight for the interesting solutions, illustrated with code examples. Finally, the summary of one year of work, and the possible directions for further improvement end the thesis.
