[RelationalDataBase]s proved very powerful but somewhat hard to use for mortals, leading to their extension. Typical extensions include: |
| |
|
4 |
# Procedural extensions to [SQL]. These lead to the current plathora of SQL variants--everyone extended SQL differently. |
| |
|
5 |
# Extensions to the relation structure to allow for variable sized fields, particularly for string data. These have much less impact than the procedural extensions to [SQL] and are largely implemented by making fields pointers to the data rather than the data itself. |
