This project contains the specialized components used to deal with Openehr RM object and persist them with using a a mixed projection (SQL + NoSQL with jsonb data type in PostgreSQL 9.4)

Please see the READMEs in each module for more details.

Building using Gradle

To build the project, Gradle can be downloaded manually and then installed system wide. An other option is to use the provided gradle wrapper which does not install anything on the system. The following examples use the Gradle wrapper for *NIX. For windows use the gradlew.bat file.

To build and test the project using gradle run:

./gradlew build

To install the JARs into the local maven repository so it can be used by other projects run:

./gradlew install

Some (older) versions of IntelliJ IDEA have difficulties importing Gradle projects. If this is the case, Gradle can create IDEA project files by running:

./gradlew idea

To find out what other tasks are available, run:

./gradlew tasks

Setting up the database

For testing

The gradle build uses flyway to manage the database schemas but before it can manage the schemas, a database must be created.

First, the following Postgresql extentions need to be installed manually:

• uuid-ossp (on Debian this is in the package postgresql-contrib)
• ltree (on Debian this is in the package postgresql-contrib)
• temporal_tables ( http://pgxn.org/dist/temporal_tables/ )
• jsquery ( https://github.com/postgrespro/jsquery )

Then run the script to create a new database and configure the extensions. See the db/createdb.sql for more details :

sudo -u postgresql psql < db/createdb.sql

(only required once)

After this, the Gradle build will take care of creating the database schemas as needed.

To empty the database, run

./gradlew flaywayClean

this will remove all data from the database.

For production

The database schemas and migration scripts can be archived into a single jar and then deployed on the production server using a command line version Flyway.
