Limitations of Apex?

Oracle Database Tips by Donald BurlesonAugust 23,  2015

Question:  My question relates to limitations of APEX.  What technical advantages do Java, JDeveloper and .NET development environments have over APEX? Can APEX use used for systems that have thousands of concurrent users and thousands of screens?  Are there secrets to using APEX for VLDB applications?

Answer:  The experts at BC have deployed Apex for very large online systems with many hundreds of screens, and Apex scales well, but there are many perils and gotchas.  As to the scalability of APEX, with the proper management of data concurrency you can easily have thousands of concurrent sessions and maintain security and data privacy.

Apex can accept embedded Java and C, so there are virtually no limitations to the power of Apex, and you can even create sophisticated screens with AJAX using Apex.  You can think of Apex as just another 4GL development platform, and it does have some distinct advantages over the lower-level tools such as JDeveloper:

  • Less up-front training - Very fast to learn
  • Easy deployment of PL/SQL
  • Not related to Microsoft

BC experts wrote the book on Apex and their book is a good place to start to see how Apex can scale for very large systems.  See the book "Easy Oracle Apex" for details.

For specific details on deploying Apex for very large applications, we have Apex experts who can advise you about all of the technical and internals details.
