I've seen it done several ways. I can't say which is best because I've never implemented a database for a company that needed multiple language descriptions.

(1) Create a separate table for each table that has globalized column and define its primary key to include all of the columns of the original table's primary key and a language identifier. Of course, this requires joins for every query that includes a globalized column.

(2) Embed the primary descriptions within your tables to speed up access, and create a separate table to contain alternate translations. "Primary" refers to the language that is most often requested and serves as the default, for example COALESCE(translated_column, primary_column) with a LEFT OUTER JOIN. This solution can improve overall performance, but that requires alternate code when translation is not needed.

(3) Create a separate table that includes all descriptive text and includes as its key the table id, column id, surrogate key value, and language id. In Microsoft SQL Server 2000, this table can be pinned in memory to boost performance. I don't know if mysql has that feature. I've seen this done once, but I personally don't think it's a good design.
