Regardless of the type of data (text documents, scanned images, audio, video, forms any binary object), it lets you store data on distributed servers and access it through a single point without knowing about the whereabouts of the data on the network. ), it lets you store data on distributed servers and access it through a single point without knowing about the whereabouts of the data on the network. 3. This is ideal, where large amounts of data of heterogeneous nature is required to be accessed through a single client application where the data could actually be located across various servers.
Make the audit trail component independent Moves audit trail implementation away from applications Not compromising security to the application developers and reduces complexity of applications ( Transparency for the app developer ) Audit based on application transactions ( “actions” ) rather than database operations Provides consistency of Audit Trail for the entire system in terms of Audit Trail Format Access to Audit Trail Audit Trail Policy Format Database components need not be concerned about Audit Trailing resulting ease of design of data schemas
Will be helpful as for developing eGov apps over Content Manger and adding new layers

An audit trail is a series of records of computer events, about an operating system, an application, or user activities.
Purpose of Audit Trail
Individual Accountability : track individual actions to facilitate audit.
Reconstructing Events : reconstruct events as and when required.
Problem Monitoring : online tools to help monitor problems
Intrusion Detection : identifying attempts to penetrate a system and gain unauthorized access.
