ContracERP does not store anything on the local desktop machine. The entire data is stored on the central server using the MS-SQL Server database application. To access a database, users must have a database user id and password. The database user account is not the same as the one used by operators when they login. Therefore, nobody in the organization (except database administrators) are aware of the access codes. Moreover, system tracks all changes to the database using a comprehensive audit trial procedure. This document can be used to determine accurately, who changed what and when.
