Moved from the Creative Cloud to the InDesign forum. They will be able to help you here.
Are trying Conditional Text?
I don't have to use a particular solution. I am only looking for the best solution.
I'd suggest that you tell us a lot more about your project if you want the "best solution." At the current level of detail, I'd say "job it out to a translation firm."
InDesign by itself cannot be populated directly by database content. You'd either need to export something from the database that InDesign can handle (XML or CSV or XLS, each with advantages and limitations) or you'd need to expand InDesign's capabilities with a third-party tool like InCatalog. There are many such tools.
Different versions of InDesign have varying degrees of support for non-Latin scripts. Once again, depending on your version of ID and your target languages, you may need to expand InDesign's capabilities in this area with third-party tools like, say, World Tools (my personal favorite).
Lastly - if you have in-house expertise in a scripting language, you may be able to do all of the above with scripting.
