LOGICAL ORGANIZATION OF APPLICATIONS WEB WITH ARCHITECTURE OF THREE LAYERS
Abstract
This research shows a web applications modeling vision, which is based on three tier architecture and its objective is to present a clear organization to the classes which compose an application.
The outcom research is a logic organization in every tier of the aplication and whatkind of classes which is contained in each tier of the model.
The propousal is based on a definided organization by class package with specific functions inherents to each tier of the model.
Therefore the paper present the topics and standars for developed of web services in context the Distributed programming.

This is the core of my research
5.1.4. Description of each layer
5.1.4.1. Layer of presentation: it contains the classes form and related others to the IGU handling. It is possible to divide to this group of classes in three packages or sub layers:
5.1.4.1 .1. It castrates IGU: It would contain classes forms, which depending on the used technology they can become applet, pages HTML (HyperText Markup Language) or XML (tensile Markup Language) [10] that interact with the user, which must have the minimum of functionality to diminish its size and to make agile its unloading.The interface of this layer with the following one becomes by means of the methods POST and GET that standard are known for many technologies.
5.1.4.1 .2. Layer of Bookstore of Presentation: It groups to the classes necessary when coming out to give format of data towards the IGU layer (Graphical interface of the User). These classes are highly re-usable.
5.1.4.1 .3. Layer of Logic of Presentation: It contains those intermediate classes between the layer of logic of the business and the IGU. These classes are those that receive or send the data from a layer to another one. They contain code but they do not have IGU, in fact they contain calls to methods of classes pertaining to his neighboring layer and can be 10 Servlet [], CGI (Common Gateway Interface) or Scripts (ASP (Page Active Server) - PHP (Pre-processing Hypertext Page)).
