<hr><a name="_details"></a><h2>Detailed Description</h2>
Abstract <a class="el" href="classGnome_1_1Gda_1_1DataModel.html">DataModel</a> (Base class for all DataModels).
<p>
A <a class="el" href="classGnome_1_1Gda_1_1DataModel.html">DataModel</a> represents an array of values organized in rows and columns. All the data in the same column have the same type, and all the data in each row have the same semantic meaning. The <a class="el" href="classGnome_1_1Gda_1_1DataModel.html">DataModel</a> is actually an interface implemented by other objects to support various kinds of data storage and operations.<p>
Depending on the real implementation, the contents of data models may be modified by the user by using functions provided by the model. The actual operations that a data model permits can be discovered using the <a class="el" href="classGnome_1_1Gda_1_1DataModel.html#c47cfc83c63af2e199b94b3523b6d419">get_access_flags()</a> method.<p>
Again, depending on the real implementation, data retreival can be done either by accessing direct random values located by their row and column, or by using a <a class="el" href="classGnome_1_1Gda_1_1DataModelIter.html">DataModelIter</a> cursor, or both. Use the <a class="el" href="classGnome_1_1Gda_1_1DataModel.html#c47cfc83c63af2e199b94b3523b6d419">get_access_flags()</a> method to discover how the data model can be accessed. Note that a Datamodel which can be accessed in a random way can also be accessed using cursors (and several cusrors may be used at the same time), whereas a data model which can only be accessed using cursors can only have one cursor for iterating.<p>
Random access data models are easier to use since picking a value is very simple by using the <a class="el" href="classGnome_1_1Gda_1_1DataModel.html#bbc4e36df6b0dc18362e56b84d1e40c1">get_value_at()</a>, but they consume more memory since all the accessible values must generally be present in memory even if they are not used. Thus, if a data model must handle large quantities of data, it is generally wiser to use a data model which can be only accessed using a cursor.<p>
As a side note there are also data models which wrap other data models such as:<ul>
<li>The <a class="el" href="classGnome_1_1Gda_1_1DataProxy.html">DataProxy</a> data model which stores temporary modifications and shows only some parts of the wrapped data model.</li><li>The DataAccessWrapper data model which offers memory-efficient random access on top of a wrapped cursor based access data model. </li></ul>
