"Relational databases started to get to be a big deal in the 1970's, and they're still a big deal today, which is a little peculiar, because they're a 1960's technology."
"A relational database is a bunch of rectangular tables. Each row of a table is a record about one person or thing; the record contains several pieces of information called fields..."
"Sometimes this is a very silly way to store information. When the information naturally has a tabular structure it's fine. When it doesn't, you have to squeeze it into a table, and some of the techniques for doing that are more successful than others. Nevertheless, tables are simple and are easy to understand, and most of the high-performance database systems you can buy today operate under this 1960's model."
