<h2>Description</h2>
<div class="description">
<p>Interface used for database preparation where we first have to register all data types (and memory output locations) before extracting data, i.e. extract works as two-pase extract: first we call prepare once, then extract n-times. Only some database connectors will need to implement this interface. Note that the values in the interface serve only the purpose of type distinction. </p>
