Case-Study: Document Circulation

Client

The client is a large governmental organization.

Problem

The client was faced with the fact that his document circulation system, written on C language and based on client-server architecture, was out-of-date and demanded thorough review. Moreover, modules in different department were not integrated, which resulted in serious lags and hindrances in document movement within the organization. The client needed a refashion of the whole system including Data Base redesign and data porting with the possibility of further integration of modules in different departments into the unified system.

Solution

Qulix was engaged as a software development company for the task.

Since existing "client-server" architecture was obviously outdated technologically, it was decided to switch to three-tier architecture with usage of all benefits of J2EE platform. Flexible solution that was developed enabled further successful integration of other modules into the common system.

Working together with the client's consultants Qulix implemented the following features into the final solution:

• Registration of ingoing and outgoing correspondence
• Registration of normative documents
• Registration and tracking of document orders
• Automatic report generation
• Search and filtration functions

Used technologies and products

• Oracle JDeveloper (IDE), J2EE (EJB, Swing);
• Oracle Application Server;
• JACOB (for printing into MS Word);
• Oracle DB Server

Project workload

The project team comprised 5 people, and project duration was 3 months.

Benefits for the customer

• New architecture brings technological benefits such as advanced level of security, good maintainability etc.
• It is possible to integrate other modules within the organization into the developed system without significant efforts
• New GUI brought additional productivity and efficiency to end users work
