Framework
and API overview

JDBC key points
 Provides a call-level API for SQL-
based database access
 Oriented towards relational
databases
 The industry standard for database-
independent connectivity
 Fits well for data centric environment

5. 5
MyBatis key points
 A JDBC Framework
 Couples objects with
stored procedures or SQL
statements
 Provides a mapping engine
that maps SQL parameters
and results to objects in a
declarative way
 It is often a good choice for
legacy or denormalized
databases

6. 6
Hibernate key points
 A framework for mapping an
object-oriented domain
model to a traditional
relational database
 An implementation of the
Java Persistence API
specification
 Provides wide feature range
and advanced configuration
abilities
 Naturally fits object centric
environment

Good to keep in mind
 When JDBC is good to use:
– Environment is data centric
– Performance critical sections
– Complex queries that return simple results
 When MyBatis is good to use:
– Environment is data centric
– Development time is essential
– Entities are unclear/complex/compound
– Logic contained in stored procedures
– SQL queries need to be fine-tuned
 When Hibernate is good to use:
– Environment is object centric
– Domain entities are clear and stable
– Variety of CRUD operations required
– Advanced cache support required
