Subject:RE: Advice on multilingual databases?
View as plain text  
Here is my suggestion, but like every other thing I post here I urge you to
take it with a grain of salt. Set up the following tables (described in
rough terms, not in SQL):

	topic_id autonumber
	... Whatever else you need to keep track of that identifies a topic

	topic_id long integer primary index
	topic_language indexed (perhaps)
	parent_topic_id indexed
	topic_language_text (utf-8, collate utf8_unicode_ci)
	... Whatever else you need that is specific to this language / topic

Now, whenever you add a topic you make an entry for a new topic, you make a
record in topic_index that identifies the topic uniquely. Make corresponding
entries in topic_detail using the topic_id that was just assigned to
topic_index's topic_id: there will be one such record for each language.

Now you can locate the topic itself in the topic_index table and quickly
pull all of the corresponding records for the different languages from
topic_detail. You can also easily find all topics that have entries in a
particular language, or that do not have entries in a particular language,
