We provide course about High-Performance Java Persistence for businesses. The High-Performance Java Persistence training is aimed to level up your data access skills, covering JDBC, Hibernate, and many database essential topics for Oracle, SQL Server, MySQL or PostgreSQL.
Course goals:
This course is meant to mind the gap between Java developers and database programming. Most often, Java developers are very skilled when it comes to programming languages, design patterns, frameworks and everything that's related to their programming language of choice. However, the database is still uncharted territory, usually treated as a black box that we throw queries at and expect it to respond in no time.
With this workshop, I want to get Java developers to know more about RDBMS so that they can design their application data access layer accordingly. After attending this workshop, you'll know all sorts of tips that you can readily apply to your current enterprise project.
