Introduction

When producing a multimedia map you have data (geometric and thematic data) that has to be stored and structured in an optimal way. There exist several possibilities how to store the needed data for a project. You can store it in separate files broken down by topic or just store everything in one database, etc. If you store the data in separate files they do not even have to be of the same file types. You are as well able to store parts of the data in text files and parts of it in databases.
