When I began as a technology coordinator, I took right to databases. I was a sponge and sought everything I could regarding them. Bernhardt was considered the expert in the field of educational databases at the time. I am self-taught. By the time the book arrived, I had surpassed the knowledge presented in this book. Even so, it was good to read something that pertained to what I was trying to do.
This is not a great book, but if someone is coming to educational technology with little knowledge, this book will probably be of some help.
