Integration Process

  1. Purpose of Integration Process:
    • The integration process is a crucial step in data mapping.
    • It integrates data from the source or loading tables into the target datastore.
    • A temporary integration table is used during this process.
  2. Integration Strategy:
    • An integration strategy defines the steps involved in the integration process.
  3. Examples of Integration Strategies:
    • Append:
      • Optionally deletes all records in the target datastore.
      • Inserts all the flow into the target.
    • Control Append:
      • Optionally deletes all records in the target datastore.
      • Inserts all the flow into the target.
      • Includes an optional flow control to manage the process.
    • Incremental Update:
      • Optionally deletes all records in the target datastore.
      • Identifies new and existing records by comparing the flow with the target.
      • Inserts new records and updates existing records in the target.
      • Includes an optional flow control for better management.
    • Slowly Changing Dimension (SCD):
      • Implements a Type 2 Slowly Changing Dimension (SCD).
      • Identifies fields that require simple updates in the target record.
      • Histories the previous record state when necessary for change management.
  4. Server Configuration:
    • The integration process may involve:
      • A single server if the staging area and target are located in the same data server.
      • Two servers if the staging area and target are on different servers.
