The document presents a proposal for developing a web-based National Data Center for Bangladesh to store and retrieve citizen information. The proposed system would reduce manual work and save time compared to the existing system. It would have three main functional components: common facilities, a module for super administrators, and a module for regular administrators. The presentation describes the system's use case diagram, entity-relationship diagram, database schema, activity diagram, data flow diagrams, state diagram, and architecture diagram. It also details a search methodology using a phonetic algorithm to allow for misspelled searches. Tools for implementation include Dreamweaver, PHP, MySQL, and testing screenshots are provided. Future plans include online public access, integration with other government organizations, and national

16. Search MethodologySearch Methodology
Objective:Objective:
High Speedy Searching from huge amount of data
To show result(s) although misspelling occurs
For these purposes we’ve used Double Metaphone
Algorithm, a phonetic search algorithm

Concept & Implementation:Concept & Implementation:
Making index of each searchable keywords by the algorithm
The Searchable words are divided in several groups identified
by unique code.

Future Plan:
Online Public Access
Linked up with other Govt. Organizations
Provide National ID card
Search by Image
If this system will be implemented, then the government of
Bangladesh would have a big savings.
