+# Mifos I/O Core data-jpa
+
+[](https://gitter.im/mifos-initiative/mifos.io?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+Data JPA provides easy access to tenant databases.
+
+## Abstract
+Mifos I/O is an application framework for digital financial services, a system to support nationwide and cross-national financial transactions and help to level and speed the creation of an inclusive, interconnected digital economy for every nation in the world.
+
+## Prerequisites
+### Runtime
+Install Java 8 as described at https://docs.oracle.com/javase/8/docs/technotes/guides/install/install_overview.html.
+
+### Installation
+#### MariaDB
+Install MariaDB as described at https://mariadb.com/kb/en/mariadb/binary-packages/.
+
+After installation you need to create the meta database:
+
+ mysql -u root -pmysql
+ CREATE DATABASE IF NOT EXISTS system_console;
+
+## Multi-tenancy
+Multi-tenancy is reached by providing separate data storage on a per tenant basis.
+
+For every tenant a new database instance is created internally. A tenant aware component provides transparent access to these resources.
+
+## Versioning
+The version numbers follow the [Semantic Versioning](http://semver.org/) scheme.
+
+In addition to MAJOR.MINOR.PATCH the following postfixes are used to indicate the development state.
+
+* BUILD-SNAPSHOT - A release currently in development.
+* RELEASE - _General availability_ indicates that this release is the best available version and is recommended for all usage.
+
+The versioning layout is {MAJOR}.{MINOR}.{PATCH}-{INDICATOR}[.{PATCH}]. Only milestones and release candidates can have patch versions. Some examples:
+
+1.2.3-BUILD-SNAPSHOT
+1.3.5-RELEASE
+
+## License
+See [LICENSE](LICENSE) file.
