createAutoMedSchema

public Schema createAutoMedSchema(AutoMedWrapper wrapper,
                                  java.lang.String schemaName)
                           throws IntegrityException,
                                  NotFoundException

Create a new AutoMed-oriented schema for the cache by summarising the BAV rules of all distinct schema objects used in the materialised views

Overrides:

createAutoMedSchema in class SQLWrapperFactory

Parameters:

wrapper - A wrapper containing the source oriented Schema from which the AutoMed oriented Schema should be produced.

schemaName - name of the new AutoMed construct oriented schema that is to be created from the source oriented schema. This schema must not yet exist.

Throws:

IntegrityException - if schemaName already exists.

NotFoundException - if you have not previously wrapped the datasource as a source oriented schema, using either #AutoMedWrapper.getSchema(String) or #AutoMedWrapper.selectNewAutoMedWrapper

newAutoMedWrapper

protected AutoMedWrapper newAutoMedWrapper()

Return a new instance of the QueryCacheWrapper

Overrides:

newAutoMedWrapper in class SQLWrapperFactory
