You’ll see that ORM is the best available solution for many scenarios, after we look at alternative tools and persistence mechanisms. to The best decision when picking a persistence solution for your own project make Our discussion of the advantages & drawbacks of ORM gives you the full background.
Managing persistent data in Java of solution to the problem, Hibernate is an ambitious project that aims to be a complete. The business problem at hand it to concentrate on Leaving the developer free, mediates the application’s interaction with a relational database. A non-intrusive solution is Hibernate. Many Hibernate-specific rules and design patterns when writing your business logic & persistent classes, by this we mean you aren’t required to follow. Thus, Hibernate integrates smoothly with most new & existing applications & doesn’t require disruptive changes to the rest of the application.
Often, these recommendations won’t be specific to Hibernate sometimes they will be our ideas about the best ways when working with persistent data to do things, We’ll cover basic and advanced features & using hibernate to develop new applications describe some recommended ways, Explained in the context of Hibernate. You need to understand the core problems of object persistence and object or relational mapping, however, before we can get started with Hibernate. Why tools like Hibernate are needed explains in this chapter. First, discuss the relationship of SQL, JDBC, and Java and we define persistent the context of object-oriented applications in data management, the underlying technologies & standards that Hibernate is built on.
The generic problems we encounter in object-oriented software development with relational databases & we then discuss the so called object or relational paradigm mismatch. Patterns to minimize the time we have to spend on the persistence-related code of our applications it become apparent that we need tools & as this list of problems grow.
