Files, Templates, Locations and Projects are related to the import/export of the PO files. Snapshots and Diffs are used to export/extract the suggestions . Projects and Categories can be used to limit the scope of the search (and other operations).
A project contains the translations of a certain application (software). A project can have several template (POT) files. A template file can have several PO files (one for each different language). Each of these PO files has many PO entries, which are stored in the table Locations.
The table Locations stores only the comments, line references, flags, previous strings, etc. of each PO entry.
The msgid (and msgctxt) of the entry is stored on the table Strings. A string can be connected to several locations, since the same string can be used on different projects.
Each string can have several translations (or suggestions) in each language. Each translation can have many votes. Each vote is given by a certain user.
