Integration Process (Simplified)
- An integration process is always required in a mapping.
- It transfers data from source/loading tables → target datastore using a temporary integration table.
- It follows an integration strategy, which defines how data is loaded and updated.
Common Integration Strategies
1. Append
- (Optional) Delete existing records in the target
- Insert all incoming data into the target
2. Control Append
- Same as Append
- Includes optional flow control
3. Incremental Update
- (Optional) Delete existing records
- Compare incoming data with target:
- Insert new records
- Update existing records
- Includes optional flow control
4. Slowly Changing Dimension (Type 2)
- Update changed fields in the target
- Maintain history of previous records for tracking changes
Server Usage
- Single Server: When staging and target are on the same server
- Two Servers: When staging and target are on different servers
If you want, I can make it even shorter for quick revision.
