Descripción
|
|
|---|---|
| The proposed invention allows modifying the structure of a record in a RDBMS table, without the need of reallocating all the records inserted previously in the table, because it allows coexisting transparently different versions of the same record with different number of fields in the same table. The invention proposes a modification of Data Dictionary and record structures, and new methods to insert, delete, modify and read records from a RDBMS. | |
