[QGIS-Developer] Factorizing a dbf

[Luiz Motta]

Hi Paolo,

A possible insight can be this:
- Create a table with two columns:  'string from SHP' and 'respective
number code'.
- In SHP create the Union with the table above.
- Use Calculator for populate the new field in SHP with value of code.

Good lucky.
