JDBC and Hibernate


JDBC and Hibernate

The acronym JDBC stands for Java database connectivity. It's what connects your program to the database and handles transactions, and it's a Java API that's open source.

Hibernate is also used to connect your application to a database and perform database-related activities, but it does so in a slightly different way. It has an object relationship library that translates the database tables and columns to java objects. It enables object-oriented database programming. Hibernate makes it possible to access database data using HQL.

  • Database connectivity technology is known as JDBC. Hibernate, on the other hand, is a framework.
  • JDBC does not support lazy loading. Hibernate supports lazy loading.
  • In JDBC, we must explicitly maintain the database connection and transaction. All transactions are managed using Hibernate.
  • To achieve caching in JDBC, we must write code. Hibernate supports two types of caching: First-level cache and second-level cache; first-level cache does not require any additional code.
  • JDBC is a slow database. Hibernate is a high-performance database.

Advantages of JDBC

The following are some of the advantages of using:

  • It can read any database. The only condition for it is that all drivers be appropriately installed.
  • It extracts data from the database and converts it to XML format.
  • It does not necessitate the conversion of the content.
  • It fully supports queries and stored procedures.
  • Both synchronous and asynchronous processing is supported.
  • Modules are supported.

Disadvantages of JDBC

It, like the majority of APIs, has several drawbacks. Here are some drawbacks listed below:

  • When it comes to the driver, it is delicate. As a result, installing and deploying the necessary drivers for each type of database is critical to use it. This is a time-consuming and, at times, difficult task.
  • It is impossible to update or insert several tables using a single sequence.
