SOA, Multi-Tier Architectures and Logic in the Database
Programmers, webmasters, Web services developers and database administrators (DBAs) are not strangers to the "Can we have it tomorrow?" request. That's why software and web developers have embraced a continuous stream of silver bullet technologies that promised to accelerate development. The developer community has experienced "web time", object-oriented programming (OOP), rapid application development (RAD), "extreme programming" and "agile development". Accelerated development schedules put a premium on understanding architecture and knowing how to match the tools to the job. That means understanding today's model of applications as services and what role a database can play. If you understand SQL technology, for example, you can adapt databases to application and service requirements by embedding logic in a database.
