public DataStore createDataStore(Map params) throws IOException
DataAccessFactory
You can think of this class as setting up a connection to the back end data source. The required parameters are described by the getParameterInfo() method.
Magic Params: the following params are magic and are honoured by convention by the GeoServer and uDig application.

params
- The full set of information needed to construct a live
data store. Typical key values for the map include: url -
location of a resource, used by file reading datasources. dbtype
- the type of the database to connect to, e.g. postgis, mysql
IOException
- if there were any problems setting up (creating or
connecting) the datasource.public DataStore createNewDataStore(Map params) throws IOException

Interpretation of FeatureDescriptor values:
This should be the same as:
Object params = factory.getParameters();
BeanInfo info = getBeanInfo( params );
return info.getPropertyDescriptors();
