多维集群(V 8GA)：使用块索引，数千个记录共用一个索引条目，实现索引压缩。
Multidimensional Clustering (V8 GA) : Implements a form of index compression by using block indexes, one index entry for thousands of records.
AdvancedDBA考试涉及到联邦数据库、分区、具体化的查询表和多维集群表。
The Advanced DBA exam gets into federated databases, partitioning, materialized query tables, and multidimensional clustering tables.
为了获得更好的性能和最小化空间消耗，我们建议使用数据库分区、范围分区、压缩和多维集群。
For best performance and minimal space consumption, we recommend using database partitioning, range partitioning, compression, and multi-dimensional clustering.
如果目标表是多维集群化(Multidimensional Clustering,mdc)表，则源表也必须是mdc表。
If the target table is a multidimensional clustering (MDC) table, the source table must also be an MDC table.
在下一个版本的SAPBW产品中，fact表将使用多维集群(multidimensional clustering,MDC)表来存储数据。

除了索引外，Design Advisor还提供关于物化查询表(MQT)、多维集群表(MDC)和数据分区功能(DataPartitioning Feature,DPF)分区键的建议。
The Design Advisor now provides advice on materialized query tables (MQTs), multidimensional clustering tables (MDCs), and Data partitioning Feature (DPF) partitioning keys, in addition to indexes.
