First Level Cache

What is cache?

The cache is a type of memory that stores data temporarily in it. This data helps websites, browsers, or apps load or start faster. Whether it is a computer, laptop, or mobile, you will find a variety of cache in it. Because of cache, the data retrieval gets faster, and the speed of apps, websites, or browsers increases. The cache is stored in fast-access hardware, e.g., RAM.

First Level Cache

Hibernate has two types of cache: the first is the first level, and another one is the second level. The first level cache is the session-level associated with a session object. The first level cache is used to decrease the interaction of the database by storing the state of the object. It does not constantly update the object after every modification, and it only updates the object at the end of the transaction. This level cache is enabled by default.

Advantages of Cache memory

  1. Cache is faster than main memory.
  2. You can access data faster than main memory.
  3. As the speed of data access increased, CPU speed increased.
  4. Store data for temporary use 
  5. Increase the output speed and throughput 

Future Scope of Hibernate

Hibernate is a java based framework used for mapping object-oriented domain models to relational databases. This framework provides various features that make it popular; multiple companies hire hibernate-based developers. You can learn the Hibernate framework and java language available on various online platforms.
