Application Description

Design of the main classes that make up the application, based on the project layout.

Basic objects classes definitions according to the application requirements and database structure.

Utilizing C# language capabilities like inheritance, accessibility and generic collections for component–based implementation.

Object Oriented Methodologies

Singleton DAL – for multiple users access synchronization.

Modeling real world objects◦ Strong types definitions◦ Objects’ state and behavior definition

Data access implementations◦ Safe connection to the database◦ Transactional manner for inserts and updates◦ Writing stored procedures based on possible data analysis and

flows.

Data Access Layer

Data Access Layer

Database provider independent layer. Enforces security and carries out validation when extra

precautions is needed. Functions as the bridge between the web site and the

data access layer. Gets instructions from the presentation layer and sends changed objects back into this layer.

Business Logic Layer

Business Logic Layer

Supporting all data scenarios using various data source controls and views with insert and update capabilities.

Using AJAX technology for effective data access and page loading.

User oriented GUI design. Providing consistent page layout that supports all use

cases.

Presentation Layer

Presentation Layer – Screen Shots
