Master Java Web Services and REST API with Spring Boot- Step 2: World before JPA - JDBC, Spring JDBC and myBatis

The video tutorial explores the evolution of database interaction methods before JPA, focusing on JDBC, Spring JDBC, and MyBatis. It highlights the manual handling of queries and parameters in JDBC, the simplification provided by Spring JDBC through templates, and the XML/annotation-based mapping in MyBatis. The tutorial also addresses the challenges of maintaining complex queries, setting the stage for the introduction of JPA in the next video.

What are the three approaches discussed in the video that were used before JPA?

• Spring JDBC, JPA, and Hibernate

• Hibernate, JPA, and MyBatis

• JDBC, Hibernate, and Spring

• JDBC, Spring JDBC, and MyBatis

In JDBC, what is required after writing a query?

• Creating a statement and setting parameters

• Directly executing the query

• Using an ORM tool

• No further steps are needed

How does Spring JDBC simplify the process compared to traditional JDBC?

• By automating exception handling

• By using XML configurations

• By providing a JDBC template

• By eliminating the need for queries

What feature does Spring JDBC introduce to simplify parameter mapping?

• Row Mappers

• XML Configuration

• Annotation-based Mapping

• Automatic Query Generation

What is a common misconception about MyBatis?

• It maps objects to queries

• It simplifies query writing

• It is an ORM framework

• It uses XML for configuration

How does MyBatis handle mapping compared to JDBC?

• Through XML or annotations

• By automating exception handling

• By using a JDBC template

• By eliminating the need for queries

What is a major challenge with using queries in JDBC, Spring JDBC, and MyBatis?

• They become complex and hard to maintain

• They automatically update with database changes

• They require no understanding of databases

• They are too simple to maintain
