Master Microservices with Spring Boot and Spring Cloud - Step 2 – World Before JPA – JDBC, Spring JDBC, and myBatis

The video tutorial introduces pre-JPA approaches like JDBC, Spring JDBC, and MyBatis, explaining how each handles database queries and parameters. JDBC requires manual query handling, while Spring JDBC simplifies this with a JDBC template. MyBatis uses XML and annotations for mapping. The video highlights the challenges of maintaining complex queries, setting the stage for JPA's introduction in the next video.

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

• JDBC, Spring JDBC, and MyBatis

• Hibernate, JPA, and MyBatis

• JDBC, Hibernate, and JPA

• Spring JDBC, Hibernate, and JPA

In JDBC, what is required after writing a query?

• Creating a statement and setting parameters

• Directly executing the query

• Using annotations for mapping

• Utilizing a JDBC template

What does Spring JDBC provide to simplify the process?

• Automatic query generation

• Direct database access

• A JDBC template

• Complex query handling

How does Spring JDBC make parameter mapping easier?

• By automating exception handling

• By using direct database connections

• By eliminating the need for queries

• By using a JDBC template

What is a common misconception about MyBatis?

• It eliminates the need for queries

• It is an ORM framework

• It uses XML for configuration

• It simplifies query writing

What is a key challenge with maintaining complex queries?

• Limited query languages

• Insufficient query tools

• Lack of database knowledge

• Changes in table relationships

What does MyBatis use for mapping?

• Database triggers

• Java code only

• Direct SQL queries

• XML or annotations
