Some questions to consider --

• How big is the final dataset going to be?
• How many users will be accessing it simlutaneously?
• Is it readonly or read/write?
• What kind of queries would you want to do?
• Will it be stored in the program or externally?

Some choices --

• AoH in the program
• flat text file
• XML
• use DBD::Sprite
• SQLite
