about =
The about tables contain database meta data.
lookup
The lookup tables contain hard-coded reference data.
A lookup table must contain a 'a_{name}_enum' column which identifies a row. The 'a_{name}_enum' column is usually be a DBT_UINT8.
If an optional 'a_{name}_char' column exists it must be of type DBT_ASCII_CHAR_BIN. The PHPBOM library will use lowercase char codes and applications can use uppercase char codes.
If you're extending a PHPBOM lookup table you should code from the max enum down.
