A Metrics Management database stores measure data for multiple types of periods. A period is the unit to use for storing data and formula measures. When you create a database, you choose the period types to create in the database. The database must include period types for which you collect data and the reporting periods for which users need performance information.

Yearly is a mandatory period type. Additional supported period types are quarterly, monthly, and daily. Typically, a database contains monthly, quarterly, and yearly period types. For example, if you collect data only on a quarterly basis, choose quarter as a period type for the database. If users view quarterly reports, choose quarter as a period type even if you collect data monthly only. A database with daily periods requires considerably more storage space and data input.

Metrics Management can support defining a period structure that does not appear by default, such as a weekly period. To define additional periods, consult with Actuate Professional Services.
