This video, presented by Cris Ippolite, makes a comparison between flat files and relational databases made with FileMaker Pro 10. It starts by showing that programs like Microsoft Excel uses, what in the databases circles, are called flat files. This flat files have a big disadvantage: it cannot communicate with other files even those have related data. So, instead of using those, if you want to ease your job, you should use relational databases. With databases, the tables communicate between them. Once you stored one entry in a table, you can use it in all other tables without the need to store it again there. This way the relational databases eliminate redundant data entry. All these things can be done with FileMaker Pro 10! Good luck!
