So, there are two basic types of databases I may have to work with in VDP production: simple, single table databases or relational database?
That’s right. Relational databases are used to collect a myriad of information about something. You could put all of the fields in a single table, but that could become quite complex and overwhelming when the number of fields in a record counted into the hundreds. A technique used to keep the tables simplified (as well as to provide productivity for the computer program, which isn’t required to sort through every field when you are interested in only a few) is to break them into smaller tables with relational links. You can quickly get to the data you need without having to process every bit of information. The science devoted to this is called database management.
