Assimilation › Considerations

Considerations

There are some considerations associated with assimilation. Resulting from the way CA 2E implements a data model, considerations involve

• i OS field names and field naming in CA 2E
• Inconsistent implicit data model
• Date formats

Whether these considerations will prove restrictive depends on

• The extent to which you wish to preserve the existing database
• Names used in the existing database
• The extent of the "correctness" of the model as implied by the assimilated set of i OS files

In making this implied model explicit, assimilation tends to highlight any inconsistencies such as missing keys, redundancy, conflicting field lengths, or the association of an attribute with the wrong entity.
