In this episode, we continue the series of overview discussions. This time around we will cover a databases overview. We looked at SDLC in the prior installment of this series and will discuss databases in a two-parter. This first part includes definitions and high-level summaries of database engines, types, and terms.
Databases Overview – The Engines
To the untrained observer, a database is a place to store data. This definition works well if you do not need to go any deeper. Unfortunately, we do, and one of the critical distinctions among databases is how they store that data. This fact is not easier to learn by the abbreviations used in talking about them. One of the more significant parts of this episode covers RDBMS, OODBMS, ISAM, and other major engines as well as what makes them different. This is an essential first step in getting us comfortable with the world of data storage.
