  To map these database tables and columns to your SDO types and properties, 
you can provide a "Type Name" and "Property Name". In the above example, if we 
specify a Type name of "employee", the DAS will attempt to create !DataObject 
instances of type "employee" from the information in the BANK_EMPLOYEE table. 
  
- It is not necessary to specify any sort of mapping between database column 
data types and your Property data types. If the data types do not match, a 
conversion will be made between the two when the property is set on the SDO 
model. The possible data type conversions are specified in the SDO 
specification. If there is no valid conversion available between the two data 
types, you can specify a Converter (see Converters) that the DAS will use to 
convert the data before setting the value in the !DataObject.
