Tables, records, and fields can be added or removed without changing any existing data. This is of great benefit in systems that change or grow rapidly. These custom areas are maintained even when a new version of the application is delivered. We do not know the existence of any other system that allows developed applications to be enhanced in this way. Only the data that is actually entered uses space.
All textual data can be any length.
There is no need to define a length for any field except to retain compatibility with traditional databases. This feature is very important for medical records or other transactional type data where extensive amounts of various types of data needs to retrieved, copied, and transmitted as a unit. We created a test suite that compared Oracle and DB2 indexes. We have filed preliminary patent papers for this unique index because it is definitely superior to anything that we have seen. Data is stored in binary format which allows for compressed data as well as encrypted data.
