Persistence - Attributes are permanently stored on a hard-drive or other fast, reliable medium until explicitly removed or changed.
Query Ability - Querying is the process of requesting attribute information from various perspectives and combinations of factors.
Concurrency - Many people may want to change and read the same attributes at the same time.
Backup and Replication - Often copies of attributes need to be made in case primary disks or other equipment fails.
Rule Enforcement - Often one wants to apply rules to attributes so that the attributes are clean and reliable.
Security - Often it is desirable to limit who can see or change which attributes or groups of attributes.
Computation - There are common computations requested on attributes such as counting, summing, averaging, sorting, grouping, cross-referencing, etc.
Change and Access Logging - Often times one wants to know who accessed what attributes, what was changed, and when it was changed.
Automated optimization - If there are frequently occurring usage patterns or requests, some Database Software can adjust themselves to improve the speed of those interactions.
Meta-data Repository - Meta-data is information about information.
Modeling Tool - A Database Software can also act as a modeling tool.
