Let my have you go through the project contents :

Database of 2 GB
10 engineers on field to fill the data in First Stage through intranet
5 Engineers to fill data in Second Stage through intranet
200 users access data to fetch reports in excel format, access format,
graphs (Microsoft Applications)
Data filled by field engineers are to be represented in forms and to be
stored in database on server
Manipulation of data in SQL/MYSQL
Authentication of data during entry
Server to be on a desktop
Each users have different roles hence need to give different rights for
report generation
21 high end users to manipulated any data set records
Now the data is to be filled through intranet
