| Apache JDO Documentation Template |
| ================================== |
| This template derived various aspects from Apache Deltaspike template, the Apache ISIS template and the Datanucleus template. |
| This template uses |
| * Bootstrap v3.3.7 (https://getbootstrap.com/) for navbar. |
| * Asciidoctor "foundation" CSS |
| * Bootswatch "cosmo" theme for Bootstrap (https://bootswatch.com/cosmo). |
| * Bootstrap TOC plugin v0.4.1 (https://afeld.github.io/bootstrap-toc/) for the table of contents. |
| * jQuery (necessary for Bootstrap's JavaScript plugins) |
| * Font-Awesome for some icons used by Asciidoctor |
| NOTE: tried using Font-Awesome CSS hosted locally but then fails to work! |

| <div class="paragraph"> |
| <p>Welcome to Apache JDO, a project of the <a href="http://db.apache.org/">Apache DB |
| project</a>. Our goal is a thriving community of users and developers of |
| object persistence technology.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Java Data Objects (JDO) is a standard way to access persistent data in |
| databases, using plain old Java objects (POJO) to represent persistent |
| data. The approach separates data manipulation (done by accessing Java |
| data members in the Java domain objects) from database manipulation |
| (done by calling the JDO interface methods). This separation of concerns |
| leads to a high degree of independence of the Java view of data from the |
| database view of the data.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Interfaces are defined for the user’s view of persistence:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>PersistenceManager: the component responsible for the life cycle of |
| persistent instances, Query factory, and Transaction access</p> |
| </li> |
| <li> |
| <p>Query: the component responsible for querying the datastore and |
| returning persistent instances or values</p> |
| </li> |
| <li> |
| <p>Transaction: the component responsible for initiating and completing |
| transactions</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>JDO is being developed as a Java Specification Request in the Java |
| Community Process. The original JDO 1.0 is |
| <a href="http://www.jcp.org/en/jsr/detail?id=12">JSR-12</a> and the current JDO 3.1 |
| is <a href="http://www.jcp.org/en/jsr/detail?id=243">JSR-243</a>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The Apache JDO project is focused on building the JDO API and the TCK |
| for compatibility testing of JDO implementations. Commercial and open |
| source implementations of JDO are available for relational databases, |
| object databases, and file systems. If you need an implementation for |
| building a JDO application, see <a href="impls.html">Implementations</a>.</p> |
