An exception that provides information on a database access warning or other warnings.
Package com.sas.storage.olap Description
Provides a set of interfaces for accessing OLAP data.
This is a Java OLAP API which can be used to execute data queries, primarily
MDX, and read the results of these queries. It can also be used to request
and read metadata from OLAP data sources, known as Cubes. In addition to
this API, this package also includes some utility classes for common operations
and performance tuning.
OLAPDataSetInterface -- primary interface for OLAP Data Access
ResultSetInterface -- retrieving the results of a query
ResultSetMetadataInterface -- provides information about the structure of
a ResultSetInterface object
AxisInterface -- provides information about each Axis of a
ResultSetMetadataInterface object. An Axis is a set of tuples.
TupleInterface -- provides information about each Tuple of a AxisInterface
object. A Tuple is an ordered collection of TupleElements from different
TupleElementInterface -- provides information about each TupleElement of a
MetadataInterface -- primary interface for OLAP Metadata Access
SchemaInterface -- provides information about an OLAP Schema, including
the Cubes contained in that OLAP Schema
CubeInterface -- provides information about a Cube, including the Measures
and Dimensions contained in that Cube. A Cube is a logical set of data that
is organized and structured in a hierarchical, multidimensional arrangement.
A cube includes measures, and it can have numerous dimensions and levels of
MeasureInterface -- provides information about a Measure. A Measure is a
special dimension member that usually represents numeric data values that
DimensionInterface -- provides information about a Dimension, including
the Hierarchies and Members contained in that Dimension. A Dimension is a
group of closely related hierarchies. Hierarchies within a dimension
typically represent different groupings of information that pertains to a
single concept. For example, a Time dimension might consist of two
hierarchies: (1) Year, Month, Date, and (2) Year, Week, Day.
HierarchyInterface -- provides information about a Hierarchy, including
the Levels and Members contained in that Hierarchy. A Hierarchy is an
arrangement of members of a dimension into levels that are based on
parent-child relationships. Members of a hierarchy are arranged from more
general to more specific. For example, in a Time dimension, a hierarchy
might consist of the members Year, Quarter, Month, and Day. In a Geography
dimension, a hierarchy might consist of the members Country, State or
Province, and City. More than one hierarchy can be defined for a dimension.
Each hierarchy provides a navigational path that enables users to drill down
to increasing levels of detail.
LevelInterface -- provides information about a Level, including the
Members contained in that Level. A Level is an element of a dimension
hierarchy. Levels describe the dimension from the highest (most summarized)
level to the lowest (most detailed) level. For example, possible levels for
a Geography dimension are Country, Region, State or Province, and City.
MemberInterface -- provides information about a Member. A Member is a name
that represents a particular data element within a dimension. For example,
September 1996 might be a member of the Time dimension. A member can be
either unique or non-unique. For example, 1997 and 1998 represent unique
members in the Year level of a Time dimension. January represents non-unique
members in the Month level, because there can be more than one January in
the Time dimension if the Time dimension contains data for more than one
OLAPException -- thrown by most methods when there is a problem accessing
data and by some methods for other reasons
OLAPWarning -- thrown to indicate a warning
A couple of implementations of this API that are readily available as part of
the sas.storage.jar are the "sasmdx" implementation and the
"embedded" implementation. The "sasmdx" implementation
provides live access to the SAS OLAP Server. The "embedded"
implementation supports the building an maintaining of an in-memory
multidimensional result set. This implementation includes the APIs for Data
Access, but not those that are used for Metadata Access. See package
documentation for more details on these two implementations.
