such as mail merging, but since TEX is designed as a typesetting language, don’t expect this bundle to perform as efficiently as custom
database systems or a dedicated mathematical or scripting language.
This bundle consists of the following packages:
datatool Main package providing database support. Automatically loads
datatool-base.
datatool-base Provides the main library code for numerical and string
functions. Automatically loads datatool-fp or datatool-pgfmath
depending on package options.
databar Package for drawing bar charts. Automatically loads datatool.
datapie Package for drawing pie charts. Automatically loads datatool.
dataplot Package for drawing simple line graphs. Automatically loads
datatool.
databib Package for loading a bibliography into a database.
Automatically loads datatool.
person Package for referencing people by the appropriate gender
