In Summary
The mnemonic dictionary is of particular value to the analyst community. The mnemonic dictionary is a natural starting point to finding data that is stored on spreadsheets.
In many ways, the mnemonic dictionary is a natural extension of the corporate data dictionary. The corporate data dictionary applies to all sorts of data in the corporation, while the mnemonic dictionary applies only to spreadsheet data. Nevertheless, the mnemonic dictionary plays a complementary role to the corporate data dictionary.
The mnemonic dictionary holds metadata as does the corporate data dictionary. The difference is that the metadata found in the mnemonic dictionary comes from spreadsheets, whereas the metadata found in the corporate data dictionary comes from sources other than spreadsheets. However, both the mnemonic dictionary and the corporate data dictionary hold metadata.
