DM
This is the simplest type of DataMeasure. It uses a SqlDef provided in the TLV definition. Platform executes the query, fetch the results and display the aggregated values in appropriate buckets.
<DM bucketization="DAILY">	<Name>RequestQuantity</Name>	<DisplayName>Request Quantity</DisplayName>	<SqlDefName>DummySql</SqlDefName>	<SqlQuantityField levelType="Undefined">		<FieldName>quantity</FieldName>	</SqlQuantityField>	<SqlDateField levelType="Undefined">		<FieldName>the_date</FieldName>	</SqlDateField></DM>- SqlDefName: One of SqlDefName or SqlDefRef must be provided. SqlDefName is the name of a query from the SqlDefs section of this TLV definition. 
- SqlDefRef: Often we define a single query to be used across multiple TLV definitions. To re-use the same SqlDef across multiple TLVs, SqlDefRef is used. This takes GroupName and SqlName for the SqlDef defined in a *.sqls file in a module (your module or a module you depend on). 
- SqlQuantityField: quantity field from the query result set for displaying values in the buckets. 
- SqlDateField: Date field from the query which determines which date each quantity corresponds to.
