ENTERPRISE RESOURCE PLANNING

Overview:

                    This project is based on the ERP (Enterprise Resource Planning) concept where the integration of different departments is the fundamental idea put across. One organization is the co-ordination of the different departments like HR (Human Resource), Accounts, Purchase and Inventory etc. Nowadays every enterprise requires a solution where they can intercommunicate with each other at the end of the day they can come to a conclusive part which will justify the process flow in the organization and that will generate filtered data and the reports which will help the department heads to concentrate more on the decision making process.

                    The present solution is being developed using the .NET technology, which is considered the finest technology to integrate different technologies and platforms. As far as the future enhancement are concerned the application is platform and architecture independent and redeployable and reusable. The project has taken the departmental details in the corresponding modules and has found integration among other modules.

2. System Analysis

2.1 Existing System

  

                      Existing system is working as Windows NT 4.0 intranet network and all the systems are using the Microsoft VB (Visual Basic) as the front end. Each module (individual) in the remote system is connected to the main server. The server is installed with oracle 8i RDBMS. The present solutions are using the Client-Server Architecture. There is no three-tier architecture as such. So any requirements changes asked by the company system configuration in terms of the solution architecture as well the business logic has to be changed from the ground as well as lot of alterations. The existing system is not compatible in terms of hardware and software. As the present solution is Microsoft Technology solution is run able on Microsoft platform only.

2.2 Limitations of Existing System

Existing System

                         The system is built using Microsoft technology i.e., Visual Basic and the backend are Oracle 8i. The system is not configurable to run Unix Servers, as Visual Basic is not supported by it.

2.3 Proposed System

                   The network is built on the Windows 2000 Server platform because of security reasons. Along with this Windows 2000 operating system we are using SQL server 2000 and the .net technologies. Here we make use of the VB.net with SQL server with which we can implement three-tier architecture. Using VB.net we can develop all User Interface application such as form designing, report designing, etc. SQL Server can be used to store the huge amount of data and has higher security of data.

2.4 Advantages of the Proposed System

The application is feasible for the economic as well as the technical advantages it gives. The main advantages are

a)     As the solutions are integrated and developed on the .NET technology, it provides multi functionalities.

b)    The solution is built purely on the .NET technology using the latest version of Visual Studio 1.1. So the solution is platform independent and supports different RDBMS packages.

c)     The Visual Studio 1.1 based solution is defined as the solution for the enterprise wide application where each and every system are integrated on the .NET framework platform for the smooth communication among different technologies and solutions. The present scenario in the market requires the enterprise wide solutions where it should be having the capability of converting itself into web services and for that the provisions of XML (Extendible Mark Up Language) has been introduced.

d)    For the fourth generation Internet users it is good news that our solution is feasible to deploy on the Internet.
