Why you don’t want to become an Oracle SOA developer

My answer on Quora to a Java developer looking to become an Oracle SOA developer:

You don’t want to become an Oracle SOA developer, for two reasons: SOA and Oracle.

First, Service-Oriented Architecture has over-promised and under-delivered for a decade. The only reason SOA is still around is that many big enterprises has invested millions of dollars and are unwilling to admit that SOA was a mistake. It takes skilled architects, care and attention to realize the benefits SOA promised, and most organizations didn’t have that.

Second, Oracle is focusing on their cloud products, and the future of on-premise SOA is uncertain. All new features are rolled out in cloud services first and then, maybe, eventually, in the on-premise products.

Instead, learn micro service architecture and the associated technologies. Modern application landscapes are too complex for centralized SOA architectures, but micro services can be rolled out and integrated with the speed modern organizations need.

If you want to stay close to the old Oracle SOA world, look at Integration Cloud Service and Process Cloud Service. That’s where exciting development is happening in the Oracle world.

How does MariaDB compare to Oracle?

My answer on Quora to “How does MariaDB compare to Oracle?”

Nobody uses MariaDB, don’t go there. You should compare MySQL to Oracle instead.

MariaDB is a fork of MySQL created by the original MySQL developers. They had cashed out and sold MySQL but hated the idea that Oracle bought their baby. According to DB-Engines Ranking, MariaDB is at place 20 with a popularity score of 45. MySQL is in second spot with a 1380 score, only a whisker behind Oracle at 1404.

Comparing Oracle and MySQL:

  • Oracle has every feature you can dream of, including a powerful proprietary programming language, and scales up to ridiculous sizes and speeds. If you need some of that, it’s worth the high cost
  • MySQL has every feature a normal developer needs in a database, and even the free community edition will meet most needs.

Which is the best career path: Oracle ADF or Java?

My answer on Quora to “Which is the best career path to choose, Oracle ADF, or Java?”

Concentrate on Oracle ADF. ADF skills are in high demand and pay better than pure Java skills.

Because Oracle ADF is a Java-based framework, you will need to learn some basic Java as you build you ADF skills. Once you land an ADF job, you will learn more Java as you work with ADF. This allows you to continue to pure Java or other frameworks if you are not happy with ADF.

Who should create Oracle ADF skins?

My answer on Quora to “Who should create Oracle ADF skins: Developers or designers”

If you are on the latest ADF version (12.2.1.x.x), you have access to the web-based Theme Editor. In this case, your designer should use this user-friendly tool to create the skin. It has some limitations, but the designer is best placed to work around these.

In earlier ADF versions, a CSS developer is needed to develop the skin, and the designer just produces a graphic in photoshop or similar. If you don’t have a specialized CSS developer, somebody will have to learn CSS, because ADF skinning uses all normal and some uncommon CSS features.

Who should override and apply Oracle ADF skin into pages developer or designer?
