A tedious analysis process then begins, usually with a debug set somewhere in the org.springframework packages. Something that should keep working under certain conditions, just ceases to work at some point. Spring Proxy and blessings of Spring sometimes become our curse. The code presented in the examples was simplified as much as possible in order to improve readability. This piece is only an introduction to a number of issues that come with the relational database in enterprise-class applications in subsequent publications I’ll present new topics or go deeper into those already presented. It also gets interesting when we want to ditch an application server that usually greatly facilitates transaction management. Sometimes things just don’t save, or save in excess, other times we lock things down or can’t see data that should be in the database. However, during the implementation of the CCB project, as well as others, I noticed that problems related to data access are still a big part of programmers' struggle. It would seem that the topics covered here should already be well known, not causing too many problems – after all, the issues we will be dealing with (such as JPA, JTA, Hibernate, Spring transaction management) are not new. After all, the first association we have in terms of technical transactions are payment transactions in banking systems, along with the need to maintain the correct system status – both when these transactions are being executed, and after that. It’s a powerful platform for streamlining all banking operations, which makes it an excellent example in terms of discussing data consistency. One of the biggest projects I had a chance to participate in during my long-term programming adventure is called Comarch Corporate Banking (CCB). The experience shows that the bigger the project, the more interesting problems we encounter on our way.
