This is a collection of small and focused instances - each covering a single and well defined approach in the area of the java application development grouped by modules. Each module is supposed to provide a separate simple instance. In this project each module presents a small simple instance of the database layer realization of a RESTful service. A strong focus of these is, of course, the different ORM Pattern realizations.

This project includes the follows modules:

• active-jdbc - is a simple realization of the Active Records Pattern via ActiveJDBC implementation in the spring-boot application;
• hibernate-jpa - is a simple realization of the Data Mappting Pattern via Spring Data JPA and Hibernate implementation in the spring-boot application.
• hibernate-jdbc-template - is a simple realization of the Data Mappting Pattern via JdbcTemplate and Hibernate implementation in the spring-boot application.

• The simple examples of the different ORM Pattern realizations.

• For more information on a releases, a features and a changes, please read the changelog notes.

These instructions allow to get a copy of this project and run it on a local machine.

Before using it, make sure that follows software are installed on the local machine:

• Oracle JDK 8+ - java development kit;
• Maven 3+ - dependency management;
• Docker Compose - tool for defining and running multi-container Docker applications.

If any of the listed software is not installed, then it can be installed by instruction as described below.

1. Oracle JDK 8+

   • Install Oracle JDK 8+ according to instructions from an official instruction.

2. Maven 3+

   • Install Maven 3+ according to instructions from an official source.

3. Docker Compose

   • Install PostgreSQL 9+ according to instructions from an official source.

In order to install it is quite simple to clone or download this repository.

For the cloning this repository to a local machine, just use the follows link:

https://github.com/ololx/orm-patterns-instances

To use it is necessary to: 1 - Build the project. 2 - Launch the instances. 3 - Instrument if (for the active-jdbc module).

To do the full build, execute maven goal install in the root directory by the following command:

mvn clean install

To do the full build, execute maven goal install in the module directory by the following command:

mvn clean install

To do the run examples, execute maven goal spring-boot:run in the module directory by the following command:

mvn spring-boot:run

This is a multi-module project. Each model is supposed to provide a separate example. That's why when you're working with an individual module, there's no need to import all of them (or build all of them) - you can simply import that particular module in either Eclipse, NetBeanse or IntelliJ IDEA and run each example in IDE.

The module active-jdbc must be instrumented before launching via maven instrumentation plugin

• Oracle JDK - java development kit;
• Maven - dependency management;
• PostgreSQL 9+ - database management system;
• Docker Compose - tool for defining and running multi-container Docker applications.
