cBioPortal Database Versioning

We follow the following logic when deciding how/when to increment the version of cBioPortal database. It's a complete modification of semantic versioning (MAJOR.MINOR.PATCH) more suitable for our purposes:

MAJOR : A non-backward compatible significant change in the database. Which requires the maintainer to reload and re-import all studies in the database entirely.

MINOR : Triggered by any of the following changes:

• Deleting a table
• Dropping a column
• Adding a constraint
• Dropping a constraint
• Renaming a table
• Renaming a column

PATCH : Changes that don't change existing database schemes but add new tables or columns, manipulating data.

• Creating a new table
• Adding a new column
• Removing all data from a table (truncate)
• Deleting rows from a table
• Updating data in a table
• Inserting rows into a table
