Years have passed dealing with Oracle products. The first days were database days for us, as in those days Oracle was mostly a database company, or maybe it is better to say, Oracle applications were not so widely used in our environment. But, later a new era came to our DBA world, as Oracle increased the importance of the application stack massively and developed and purchased business applications to deliver best-in-class business solutions, which covered almost every aspect of technology from application to disk.
In the initial stages, people who managed and maintained databases were called DBAs, and the job role of DBA became a globally recognized role in the IT industry. Database administrators have always played a critical role in organizations.
Although some might consider the database to be a component in the application layer, we have always considered Oracle Database as a system—a relational database management system that is tightly integrated with the application tier above it and the operating system beneath it. While Oracle is tightly integrated
with the application and operating system technologies, this tight integration has turned Oracle Database into sophisticated software that needs additional skills at the operating system and application layers for proper administration. So, it was expected that expert DBAs know the operating system and the application technology as well.
Once Oracle started growing and moving toward the development of business applications, new roles in the IT industry started to emerge. That is, we started learning how to manage, maintain, and administer these applications.
We actually started working with Oracle E-Business Suite 11i and continued with R12 and the administration of these application suites with the job title of Oracle Apps DBA.
