How do traditional databases and multimedia databases differ?
Traditional databases are designed to store and manage structured data like text and numbers, while multimedia databases are specifically tailored to handle multimedia data such as images, videos, and audio.

Do keyfields link data together in a database?
Yes, keyfields are used to link data together in a database.

This linking of data through keyfields enables the database to efficiently retrieve and manage related information.

Analytical databaseThese databases store data and information extracted from selected operational and external databases. They consist of summarized data and information most needed by an organization's management and other end-users. Some people refer to analytical databases as multidimensional databases, management databases, or information databases.Operational databaseThese databases store detailed data needed to support the operations of an entire organization. They are also called subject-area databases (SADB), transaction databases, and production databases. For example:customer databasespersonal databasesinventory databasesDistributed databaseThese are databases of local work-groups and departments at regional offices, branch offices, manufacturing plants and other work sites.
