# Ebean ORM for Java & Kotlin
**Multiple abstraction levels**: Ebean provides multiple levels of query abstraction [ORM Queries, mixed with SQL](https://ebean.io/docs/intro/queries/orm-query), [DTO Queries](https://ebean.io/docs/intro/queries/dto-query), [SqlQuery and JDBC](https://ebean.io/docs/intro/queries/sql-query).
Work at the highest level of abstraction and drop down levels as needed.
**Database migrations**: Built in [DB migration](https://ebean.io/docs/db-migrations/) generation and running. Support for "rebase" migrations as well as repeatable, init and 'normal' migrations.
**Awesome SQL**: Ebean produces SQL that you would hand craft yourself. Use great SQL, never generate SQL cartesian product, always honor relational limit/offset.
**Automated query tuning**: For ORM queries Ebean can profile the object graph being used and either [automatically tune the query](https://ebean.io/docs/query/background/autotune).
**Docker test containers**: [Docker test containers](https://ebean.io/docs/testing/) for all the supported databases. Get 100% test coverage on all the features of the database we use.
**Type safe queries**: We can build queries using type safe [query beans](https://ebean.io/docs/query/query-beans). IDE auto-complete when writing queries, compile time checking and it's FUN.
**Performance isn't optional**: Optimise queries to only fetch what we need (partial objects). Automatically avoid N+1 via a smart load context.
#### Benefits of ORM
* Automatically avoid N+1
* L2 caching to reduce database load
* Queries mixing database and L2 cache
* Automatically tune ORM queries
* Elasticsearch for search or L3 cache

## Building Ebean from source
- JDK 11 or higher installed
- Maven installed
- `git clone [email protected]:ebean-orm/ebean.git`
- `mvn clean install`
Ebean 13 uses Java modules with module-info. This means that there are stricter compilation
rules in place now than when building with classpath pre version 13.
For Maven Surefire testing we use `false` such
that tests run using classpath and not module-path. We are doing this until all the tooling
(Maven, IDE) improves in the area of testing with module-info.
#### Eclipse IDE
Right now we can't use Eclipse IDE to build Ebean and run its tests due to its poor support
for java modules. See [ebean/issues/2653](https://github.com/ebean-orm/ebean/issues/2653)
The current recommendation is to use IntelliJ IDEA as the IDE to build and hack Ebean.
#### IntelliJ IDEA
We want to get IntelliJ to run tests using classpath similar to Maven Surefire. To do this set:
`JUnit -> modify options -> Do not use module-path option`
To set this option as the global default for IntelliJ use:
`Run - Edit Configurations -> Edit configuration templates -> JUnit -> modify options - Do not use module-path option`
end
