Summarization Process Flow

This diagram shows the Project Data Compression process, which consists of six steps.

Project Data Compression process

The data compression and restoration process flow that the system performs is:

  1. Copy the detailed transaction rows based on the compression template and run control options from the Project Transaction table (PROJ_RESOURCE) to the Project Transaction History table (PROJ_RES_ARCH).

  2. Summarize detailed transaction rows in the Project Transaction History table and copy them to the Project Summary History table (PROJ_SUM_ARCH).

  3. Delete the original transactions from the Project Transaction table.

  4. Copy summarized transactions in the Project Summary History table to the Project Transaction table.

  5. Restore rows from the Project Transaction History table to the Project Transaction table as detailed rows.

  6. Delete compressed rows in the Project Transaction table.
