| <div class="block">Interaction with SystemDS using the JMLC (Java Machine Learning Connector) API is initiated with |
| a <a href="../../../../../org/apache/sysds/api/jmlc/Connection.html" title="class in org.apache.sysds.api.jmlc"><code>Connection</code></a> object. The JMLC API is designed after JDBC. A DML script is precompiled by calling |
| the <a href="../../../../../org/apache/sysds/api/jmlc/Connection.html#prepareScript-java.lang.String-java.lang.String:A-java.lang.String:A-"><code>prepareScript(String, String[], String[])</code></a> |

| method on the <a href="../../../../../org/apache/sysds/api/jmlc/Connection.html" title="class in org.apache.sysds.api.jmlc"><code>Connection</code></a> object, which returns a |
| <a href="../../../../../org/apache/sysds/api/jmlc/PreparedScript.html" title="class in org.apache.sysds.api.jmlc"><code>PreparedScript</code></a> object. Note that this is similar to calling |
| a <code>prepareStatement</code> method on a JDBC <code>Connection</code> object. |
| |
| <p> |
| Following this, input variable data is passed to the script by calling the |
| <code>setFrame</code>, <code>setMatrix</code>, and <code>setScalar</code> methods of the <a href="../../../../../org/apache/sysds/api/jmlc/PreparedScript.html" title="class in org.apache.sysds.api.jmlc"><code>PreparedScript</code></a> |
| object. The script is executed via <a href="../../../../../org/apache/sysds/api/jmlc/PreparedScript.html" title="class in org.apache.sysds.api.jmlc"><code>PreparedScript</code></a>'s |
| <a href="../../../../../org/apache/sysds/api/jmlc/PreparedScript.html#executeScript--"><code>executeScript</code></a> method, |
| which returns a <a href="../../../../../org/apache/sysds/api/jmlc/ResultVariables.html" title="class in org.apache.sysds.api.jmlc"><code>ResultVariables</code></a> object, which is similar to a JDBC |
| <code>ResultSet</code>. Data can be read from a <a href="../../../../../org/apache/sysds/api/jmlc/ResultVariables.html" title="class in org.apache.sysds.api.jmlc"><code>ResultVariables</code></a> object by calling |
| its <a href="../../../../../org/apache/sysds/api/jmlc/ResultVariables.html#getFrame-java.lang.String-"><code>getFrame</code></a> and |
