Release in the context of WhereScape RED
A release comprises work results (artefacts) to be issued. In the area of data warehouses, an artefact can comprise a new version of an entire data warehouse or a single object, or a specific subset of a data warehouse.
It is advisable to use a delta procedure when rolling out WhereScape RED deployments. A release is then the sum of all modified and newly created objects. This minimizes the scope of deployment, besides securing further advantages:
- Fast installation
- No recompilation of unmodified objects, thus excluding a potential source of error
- Minimization of log files, as well as consequent minimization and better management of the time required to control and check deployment
Full deployment and subset deployment can be considered as alternatives. However, these options offer no apparent added value compared to delta deployment. Of course, this always also depends on the conditions of the data warehouse and organizational structures. However, minimizing the scope of a release generally reduces the complexity of the deployment process. Dependencies become more traceable, errors are detected more quickly, and deployment is shortened to a minimum. This achieves transparency, speed and maintainability.
