-- Version 0.5.5.1 Removed character length restrictions as the docs for POSTGRESQL recommend not specifying a limit.
|
|
-- Version 0.6.0.0 Changed the numeric values to integers as Golang doesn't have a native decimal type.
|
|
-- Version 0.6.2.0 Added the first draft for cost of ownership. Added quantity to the item table.
|
|
-- Version 0.6.5.0 Added a documents table along with the tables to reference them as either an expense or as a document for an item.
