PRESERVING DEPRECATED DATABASE COLUMNS

摘要

A method of preserving deprecated database columns across application upgrades may include maintaining a database communicatively coupled to an application. The application may include a first schema. The first schema may indicate a first column for the database. The method may also include receiving an update for the application. The update may include a second schema that removes the first column from the database. The method may additionally include renaming the first column by appending a prefix to a name of the first column. The prefix may indicate that the first column is deprecated. The method may further include maintaining the first column in the database.
