Information Sharing
There is a growing need to share information across organizations. Users need a single logical view of the data relating to the situation that they are dealing with. This view needs to be governed by the security policies of the various organizations that are sharing the information. It must also be possible for organizations to add new types of data and relationships to existing databases, even when the ownership of that data may reside elsewhere.
Intranets and extranets are a partial solution to this problem, but they only apply to textual data. Sharing information across databases raises many other issues, such as:
- Data access protocols
- Data quality assurance
- Data security
- Application change control
- Potential impact on local system performance.
