Architecture and Design decisions

When it comes to MariaDB/MySQL Database consulting engagements we often see, that our customers are very confused by many different technologies advertised to them.

Storing BLOBs in the database

oli.sennhauser@fromdual.com (Oli Sennhauser) — Fri, 30 Jun 2017 14:18:07 +0000

Database Architecture & Design

Application logic in the middle tier?

Reduce money spent on software licenses by moving logic to the middle tier. This means moving stored procedures into the application server or web server layer where it is much cheaper to scale out. Reducing or eliminating business logic running in the DB may reduce Database CPU utilisation and hence save support costs for the DB Portability is key! [1]

MySQL pluggable Storage Engines (SE)

oli.sennhauser@fromdual.com (Oli Sennhauser) — Thu, 11 Mar 2010 23:20:51 +0000
