INTRODUCTION OF PROJECT
Rajiv Gandhi Grameen Vidyutikaran Yojna (RGGVY) is a nation wide programme under Ministry of Power (MoP) has been launched with an objective to electrify all villages and habitations, provide access to electricity to all rural household and give free of cost electricity connection to Below Poverty Line (BPL) families within five years. Under RGGVY, Electricity Distribution Infrastructure is envisaged to establish Rural Electricity Distribution backbone (REDB) with at least a 33/11 KV sub-station, Village Electricity Infrastructure (VEI) with at least one Distribution Transformer in a village or hamlet and stand alone grids with generation where grid supply are not feasible. This programme has been brought under the ambit of Bharat Nirman and Rural Electrification Corporation Ltd. (RECL) is the nodal agency responsible for implementation of the programme.
USER PROFILE AND PROBLEM DEFINITION
Ministry of Power (MOP) and Rural Electrification Corporation (REC) Limited are the end user of the project. As mentioned earlier, MOP – a core ministry of union government is supported by Energy Information Systems (EIS) Division of NIC for all its Information & Communication Technology (ICT) needs. The brief overview on role & responsibilities of the Ministry and REC is mentioned in following sections:
MINISTRY OF POWER
The Ministry of Power started functioning independently with effect from 2nd July, 1992. Earlier it was known as the Ministry of Energy Comprising the Departments of Power, Coal and Non-Conventional Energy Sources. Electricity is a concurrent subject at Entry 38 in List III if the Seventh Schedule of the Constitution of the India. The Ministry of Power is primarily for the development of electrical energy in the country.
The Ministry is concerned with perspective planning, policy formulation, processing of projects for investment decision, monitoring of the implementation of power projects, training and manpower development and the administration and enactment of legislation in regard to thermal, hydro power generation, transmission and distribution.
RURAL ELECTRIFICATION CORPORATION (REC) LIMITED
Rural Electrification Corporation (REC) was incorporated on July 25, 1969 under the Companies Act 1956. REC is a wholly owned Government of India Public Sector Enterprise with a net worth of Rs. 3779 Crore. Its main objective is to finance and promote rural electrification projects all over the country. It provides financial assistance to State Electricity Boards, State Government Departments and Rural Electric Cooperatives for rural electrification projects as are sponsored by them. REC provides loan assistance to SEBs/State Power Utilities for investments in rural electrification schemes through its Corporate Office located at New Delhi and 17 field units (Project Offices), which are located in most of the States.
PROJECT CATEGORY
The category of our project “Village Level Monitoring and Milestone Monitoring”.
Falls on both RDBMS & OOP’s based approach.
In support of OOP’s approach, we can use VB.6.0 as front-end because it has added some desired languages features and even more powerful database feature. The second reason, it is powerful tool for developing windows based application and it can provide ability to create true executables and even the ability to make our own control.
In support of RDBMS approach, we can select SQL as back-end as because it can reliable to manage a large amount of data in multi-user environment so that many users can concurrently access the same data. Another reason is that it can support client-server approach in distributed environment processing. It can used to achieve high transaction processing and large database & space management. It can prevent unauthorized access & provide efficient solution for failure recovery.
SCOPE OF THE PROJECT
To monitor physical and financial progress of projects under RGGVY implementation, REC has requested NIC to design, develop & implement a Web Based Management Information System. The major objectives of the desired system are:
Design and development of a Web Based System to facilitate Data entry from remote locations, generation of the desired queries/reports for monitoring purpose, depending on various milestones related criteria. Provision of an Administration module to control user authorization and role based user access to the system.
Implementation & Training to users of various categories at different locations.
SYSTEMS LIFE CYCLE
The sequencing of various activities required for developing and maintaining systems in an ordered form is referred as Systems Life Cycle. It helps in establishing a system project plan as it gives overall list of process and sub-processes required for developing any system. Here, the systems life cycle will be discussed with reference to the development of Web Based MIS for RGGVY.
STUDY OF EXISTING SYSTEM
In order to analyze the new system, it was necessary to study the existing procedures and steps being followed for monitoring RGGVY program at REC. This study included:
Discussions with REC officials at various levels
Study of on going manual system
Study of existing manuals & documents
SYSTEM REQUIREMENT SPECIFICATION
Shared, complete and accurate information requirements are essential in building computerized system. To determine the information requirements of each user is difficult task, especially in a system, which is to be implemented in major areas.
System requirement specification activity comes after the entire analysis is complete. In this phase the requirement must be specified in the Requirement Specification Document (RSD) or System requirement specification (SRS). The Requirement document must specify all functional and performance Requirements, inputs and outputs and design constraints exist due to economic Environment and security. All the factors that affect the design and proper functioning of the system should be specified in the RSD.
DATA FLOW DIAGRAMS
This section describes in detail the data flow diagramming technique. It is intended to serve as a handbook to guide the reader in developing data flow diagramming skills.
Definition:
Data Flow Diagramming is a means of representing a system at any level of detail with a graphic network of symbols showing data flows, data stores, data processes, and data sources/destinations.
