A sysadmin might specialise in various jobs. Hence we have a database sysadmin or a website sysadmin. But recently, there has been the rise of a blog sysadmin. It combines to some extent duties of the other two sysadmins. This book shows that if you want to run a blog site, and choose Movable Type, then you are basically running a database. The book offers three types. All free and open source. MySQL. PostgreSQL and SQLite. The book chooses to use MySQL when demonstrating examples. But much of these seems easily portable to the other SQLs. So if MySQL is not your game, don't let that put you off the book. The book skims quickly over the theory of relational databases, and how these are implemented in MySQL. At a higher level than the database, you access Movable Type via several APIs. Of these, the Perl API might be the most attractive, given Perl's popularity. But of all the chapters, you might want to devote the most attention to that on plug-ins. Many third parties [you?] can and have written over 100 of these. Even if you do not intend to write one, it's worth perusing what's out there on the net, just in case one fits your situation.
