+<section id="GUID-10CCFE47-6AC1-4756-BB03-FE07F589DE1F"><title>Description</title> <p>The
+API has two key concepts: database incremental operations, and DML statement
+incremental execution. </p> <p><b>Database incremental operations</b> </p> <p>This
+allows long-running database operations—table alteration and discard, database
+compaction and recovery, index creation and discard, DDL (SQL schema update)
+statement execution—to be performed in incremental steps.</p> <p>While an
+incremental operation is in progress, the database cannot be used for any
+other operations such as opening tables or preparing views. Beginning an incremental
+operation also requires that no rowsets are open on the database, and that
+no data manipulation transactions are pending a commit. </p> <p>If no explicit
+transaction has been started by the database, an automatic transaction is
+begun when any incremental operation is started and is committed when complete,
+or rolled back if the operation fails or is abandoned prior to completion.</p> <p>Database
+incremental operations are provided by <xref href="GUID-B07C2FDC-357E-31F8-B67E-0A252EEF2187.dita"><apiname>RDbIncremental</apiname></xref>.</p> <p><b>DML
+statement incremental execution</b> </p> <p>A class is provided, similar to <xref href="GUID-B07C2FDC-357E-31F8-B67E-0A252EEF2187.dita"><apiname>RDbIncremental</apiname></xref>,
+for performing DML (SQL data update) statements incrementally. This is <xref href="GUID-B9D43EA2-F1F1-3830-A16A-F73F06C2BB3D.dita"><apiname>RDbUpdate</apiname></xref>.</p> </section>
