The Space Analyzer makes use of the standard database update and summarization facilities of CA MICS to maintain its data in the online and offline databases. Data is supplied to CA MICS in the DAY090 step of the DAILY database update job. The daily update step: o Reads and formats the raw data o Maintains data integrity by eliminating duplicate data o Adds new cycles to the DETAIL timespan o Summarizes activity by hour for DAYS timespan o Adds new cycles to the DAYS timespan o Updates the month-to-date cycles Figure 9-1 shows an overview of the daily update process. A more detailed description of DAY090 processing is presented in Section 9.2. Weekly processing is performed by the WEEK090 and WEEK300 steps. The WEEK090 step splits the week-to-date files into a new week-to-date and a new weekly '01' cycle. The WEEK300 step creates the weekly offline database files. Monthly processing is performed by the MONTH090 and MONTH300 steps. The MONTH090 step splits the month-to-date files into a new month-to-date and a new monthly '01' cycle, and also updates the year-to-date cycles. The MONTH300 step creates the monthly offline database files. Yearly processing is performed by the YEAR090 step. The YEAR090 step splits the year-to-date files into a new year- to-date and a new yearly '01' cycle.
