Database Systems Supported

• MySQL
• Oracle

Nutrient Databases Included

• Health Canada, 2015. Canadian Nutrient File www.healthcanada.gc.ca/cnf
• US Department of Agriculture, Agricultural Research Service, Nutrient Data Laboratory. USDA National Nutrient Database for Standard Reference, Release 28. Version Current: September 2015. Internet: https://www.ars.usda.gov/Services/docs.htm?docid=8964 (Full and Abbreviated versions.)

Where Are the SQL Files?

The SQL files are located in the "dist" directory of each nutrient database, e.g. "usda_nndsr/dist".

Project Description

Nutriana takes the food composition data released by various official sources in the world and converts it into formats specific to the database systems mentioned above. (A good list of nutrient databases in the world is available here: http://www.langual.org/langual_linkcategory.asp?CategoryID=4&Category=Food+Composition)

How it Works

A human being is needed to extract the description and constraints of a given nutrient database into a file that can be programmatically processed. The JSON format was chosen for readability and portability reasons. Nutriana prefers not to modify the nutrient database's official data files, but to ensure successful database creation and data import, some changes may be necessary. All modifications are fully disclosed in the */MODIFICATIONS files, and typically involve correcting field size or key constraint definition, using date format instead of string, removing trailing whitespace and/or replacing "no value" indicators with "null".

If Your Preferred Database is Not Supported

It should be easy to add support for other databases by copying one of the Perl module files (*.pm) and editing it as needed to output the format for your database system. (If you find it's not, let me know by creating an issue.) Run the build.sh file to (re)generate the database vendor files. The script will automatically detect the new .pm file and attempt to output SQL for it. To alter the database name or user credentials, edit the "generate_sql.pl" file.
