Identify database security options and list candidate configurations. Archival requirements Security requirements Step 4 Description Catalog a reusable data structure for each unique data element in the databases, each data structure sharing the same global data type with its database data element. Activity 8.2 Establish Production Environment ensures that backup and recovery procedures are complete and ready for production. For some kinds of systems, this level of testing should be done to evaluate the quality of CS architecture designs. Incremental planning may lead to rework in subsequent increments.
Time is required up front to create a stable initial data model.
Increment planning and multiple physical design steps seems inappropriate. Data model can't change much once increments have been planned. GUI can change. This means that a large design requires great care in planning as well as execution. Appropriate meta-data facilitates change in subsequent increments.
