This clause retrieves dimension's information: PROPERTIES, DIMENSION_ATTRIBUTES, LEVELS, HIERARCHIES, DIMENSION_ROLES, SEQUENCE, DIMENSION_KEY, COLUMN, SURROGATE_KEY, PARENT_KEY, BUSINESS_KEYS, IMPLEMENTED_OBJECTS.
This clause gets the details of levels: PROPERTIES, LEVEL_ATTRIBUTES, IMPLEMENTED_OBJECT.
Basic properties for DIMENSION, DIMENSION_ATTRIBUTE, LEVEL, LEVEL_ATTRIBUTE and HIERARCHY: Basic properties for DIMENSION : Name: BUSINESS_NAME Type: STRING(200) Valid Values: Any valid character string in supported character set. Default: Empty string Business name of the Dimension Name: DESCRIPTION Type: STRING(4000) Valid Values: Any valid character string in supported character set. Default: Empty string Description of the Dimension Name: SCD_TYPE Type: INTEGER Valid Values: 1, 2, 3 Default: 1 Slowly changing policy to be applied on the dimension. Give Interger values 1, 2, 3 for Slowly changing type one, two and three Name: LOAD_POLICY_FOR_NULL_KEY Type: STRING Valid Values: 'NO_MAINTENANCE', 'NO_MAINTENANCE_WITH_ERROR_TABLE', 'REJECT', 'DEFAULT_PARENT' Default: 'NO_MAINTENANCE' Data policy for loading dimension where OWB mapping code relies on database constraints to detect the orphans (null parent references). 'NO_MAINTENANCE', OWB does not actively enforce the parentage integrity rule that requires every child record to have a parent. 'NO_MAINTENANCE_WITH_ERROR_TABLE', Same as NO_MAINTENANCE, and additionally an error table will be deployed, thus orphan management can be switched on at the map level. 'REJECT', the policy for loading dimension where OWB mapping code will actively detect the orphans (level records without parent) and reject them. 'DEFAULT_PARENT', the policy for loading dimension where OWB mapping code will actively detect the orphans (level records without parent) and assign them under default parent. Name: LOAD_POLICY_FOR_INVALID_KEY Type: STRING Valid Values: 'NO_MAINTENANCE', 'NO_MAINTENANCE_WITH_ERROR_TABLE', 'REJECT', 'DEFAULT_PARENT' Default: 'NO_MAINTENANCE' Data policy for loading dimension where OWB mapping code relies on database constraints to detect the orphans (could contain a value that is not actually found in the parent). 'NO_MAINTENANCE', OWB does not actively enforce the parentage integrity rule that requires every child record to have a parent. 'NO_MAINTENANCE_WITH_ERROR_TABLE', Same as NO_MAINTENANCE, and additionally an error table will be deployed, thus orphan management can be switched on at the map level. 'REJECT', the policy for loading dimension where OWB mapping code will actively detect the orphans (level records without parent) and reject them. 'DEFAULT_PARENT', the policy for loading dimension where OWB mapping code will actively detect the orphans (level records without parent) and assign them under default parent. Name: REMOVE_POLICY Type: STRING Valid Values: 'NO_MAINTENANCE', 'REJECT' Default: 'NO_MAINTENANCE' Data policy for remove dimension data where OWB relies on database constraints to detect removal of parent records who still have child records. 'NO_MAINTENANCE', does not actively enforce the parentage integrity rule that requires every child record to have a parent. 'NO_MAINTENANCE_WITH_ERROR_TABLE', Same as NO_MAINTENANCE, and additionally an error table will be deployed, thus orphan management can be switched on at the map level. 'REJECT', data policy for loading dimension where OWB mapping code will actively reject the removal of parent records who still have child records. #'CASCADE', data policy for removing dimension data where OWB mapping code will #actively detect the removal of parent records who still have child records, #and remove all of the descendents.
Name: TYPE Type: STRING Valid Values: NONE, TIME Default: NONE 'NONE' it does not recognize it as any specific type of dimension. 'TIME' dimension is a time dimension Name: OLAP_TYPE Type: STRING Valid Values: NONE, TIME Default: NONE Dimension type for OLAP, set regular dimension 'NONE' and for OLAP Time Dimension 'TIME' Name: OLAP_USER_VISIBLE Type: STRING Valid Values: true, false Default: true The dimension is visible to OLAP end user Name: UNIQUE_KEY_CONSTRAINT Type: STRING Valid Values: true, false Default: false set the Unique Key constraint on the Business Key Name: STORAGE Type: STRING Valid Values: RELATIONAL, AW Default: RELATIONAL The storage of a dimension can be AW or relational Name: AW_NAME Type: STRING(32) Valid Values: Any valid character string in supported character set. Default: Empty string Set the analytical workspace name where the dimension is implemented Name: AW_DIMENSION_NAME Type: STRING(32) Valid Values: Any valid character string in supported character set. Default: Empty string Set the Analytical Workspace dimension physical object name Name: USE_BUSINESS_KEYS Type: STRING Valid Values: true, false Default: false get the flag of Analytical Workspace dimension to use Business Keys as data source
Basic properties for DIMENSION_ATTRIBUTE: Name: BUSINESS_NAME Type: STRING(200) Valid Values: Any valid character string in supported character set. Default: Empty string Business name of the Dimension_Attribute Name: DESCRIPTION Type: STRING(4000) Valid Values: Any valid character string in supported character set. Default: Empty string Description of the Dimension_Attribute Name: DATATYPE Type: STRING Valid Values: BINARY_DOUBLE, BINARY_FLOAT, BLOB, CHAR, CLOB, DATE, FLOAT, INTEGER, INTERVAL DAY TO SECOND, INTERVAL YEAR TO MONTH, NCHAR, NCLOB, NUMBER, NVARCHAR2, RAW, TIMESTAMP, TIMESTAMP WITH TIME ZONE, TIMESTAMP WITH LOCAL TIME ZONE, VARCHAR, VARCHAR2 Default: NUMBER Sets the datatype of a Dimension_Attribute Name: SCALE Type: NUMBER Valid Values: -85 - 125 Default: 1 The scale of a number. Name: LENGTH Type: NUMBER Valid Values: Default: 1 The length of a number Name: PRECISION Type: NUMBER Valid Values: 0 - 39 Default: 1 The precision of a number. Name: DESCRIPTOR Type: STRING Valid Values: 'NONE', 'SHORT_DESCRIPTION', 'LONG_DESCRIPTION', 'END_DATE', 'TIME_SPAN', 'PRIOR_PERIOD', 'YEAR_AGO_PERIOD' Default: 'NONE' The following properties are set on dimension attribute so that it is recognized by OLAP service 'NONE' it is not specially recognized type by OLAP service 'SHORT_DESCRIPTION' sets as a short description 'LONG_DESCRIPTION' sets as a long description 'END_DATE' sets as a last date of a period. 'TIME_SPAN' sets as a number of days in a period. 'PRIOR_PERIOD' sets as the prior period number. 'YEAR_AGO_PERIOD' sets as the time period a year before this period
Name: OLAP_USER_VISIBLE Type: STRING Valid Values: 'true', 'false' Default: 'true' The dimension attribute is visible to OLAP end user Name: TYPE Type: STRING Valid Values: 'NONE', 'START_DATE', 'END_DATE', 'TIME_SPAN' Default: 'NONE' 'NONE' dimension attribute so OWB does not recognize it as any specific type. 'START_DATE' dimension attribute of time dimension as the start date of a period 'END_DATE' dimension attribute of time dimension as the end date of a period 'TIME_SPAN' dimension attribute of time dimension as the time span Name: AW_ATTRIBUTE_NAME Type: STRING(32) Valid Values: Any valid character string in supported character set. Default: Empty string set the AW object name implementing the dimension attribute Basic properties for Level : Name: BUSINESS_NAME Type: STRING(200) Valid Values: Any valid character string in supported character set. Default: Empty string Business name of the Level Name: DESCRIPTION Type: STRING(4000) Valid Values: Any valid character string in supported character set.

For Relational Time Dimension use other values. Name: OLAP_TYPE Type: STRING Valid Values: NONE,DAY,MONTH,QUARTER,YEAR,TOTAL Default: NONE Level has an olap-type for OLAP-based levels, use 'NONE' for regular levels, and other values for OLAP Time Dimension. Name: OLAP_USER_VISIBLE Type: STRING Valid Values: true, false Default: true The level is visible to OLAP end user
