Data and data access layer generator

While today?s advanced applications are developed, N-Tier Architectural structures are usually used in order to supply requirements. In that architectural structure, Data Access Layer exists on Data Layer and provides the communication between the application and database. Database access methods are defined in Data Access Layer; if it?s necessary, I/O interfaces and communication protocols are written in here too. In application developed as part of the thesis, it?s aimed to prevent from the probable mistakes, code repeat and waste of time by the data access being formed by software.In this thesis, the application that will produce Data Layer and Data Access Layer was developed on Visual Studio.NET platform by using VB.NET programming language. Database in Data Layer was provided by producing Stored Procedures as being appropriate for SQL programming language, in SQL Develop stage. Data Access Layer was developed in Class Develop stage by producing Class Codes.
