storage speeds

[rain_gloom]

If I need to store data for long periods of time and frequent access and in 2D matrices(!) what would be the best techology in terms of...

• 
  debug
  speed
  memory usage

?

I'm currently using lua tables as matrices but if I want to make back-ups or an externally editable conversion, what would be the best?

-SQL, mySQL

-XML

-or is there a method to store in raw list format that can be read by lua?

Not sure about the first question, but defiantly don't use XML to store the data.

XML maybe for client data, but not for server data.

As far as i know i suggest you to use SQL or MySql because it is the best for me .

Agree with IIYAMA .

+ SQL is better in my opinion .
