php[architect] magazine has released their March 2015 edition of their magazine - DB Migration:
Because databases store the data our applications, they need proper care and feeding too. In “DB Migrations”, David Berube shares what he’s learned to properly design your databases, Harrie Verveer looks at “Database Versioning with Liquibase”, and Patrick Schwisow shows you how to consolidate Doctrine Migrations that have gotten unwieldly.
Other topics included in this month's edition include a "deep dive" into PHP extensions, object oriented Javascript, bitwise math and much more. You can pick up your own copy - either virtual (PDF) or in print - from the php[architect] website.
