Chhattisgarh Online Information for Citizen Empowerment (CHOiCE) is a E-Governance project to empower Government to citizen services. The primary purpose of CHOiCE is to develop and maintain a community information network, which provides open access to online information for Raipur and Chhattisgarh State. The Hallmark of this community information network is the ability of the general public to obtain information that may not have been previously or easily accessible to them. Like most community networks, CHOiCE offers a variety of information and communication resources that are relevant to the local community. The creation of CHOiCE allows citizens to access government information and services. Among its many features, the system has the capability to allow citizens to send message, query database, request application, and check the status of communication made to government departments. However, it should be noted that the use of the community network would largely depend on the information being relevant, current, well indexed, useful and of interest to the target users. CHOiCE supports the placement of public- access terminal (KIOSK) in public places.Responsibility : • Preparation of Business Process Re-engineering• Preparation of SRS• Preparation of System Design Document using Case Tool(power Designer)• Development of Web Application software.• Testing • Preparation of User manual and training• Implementation• Modification• 3 tier Architecture (Web Technology)
