Database vendors focused on warehousing have invested considerable energy in optimizing their DBMS products to maximize query performance. As a result, warehousing performance has improved dramatically over the last several years. The growth in the size and complexity of warehouses has prevented some of this performance gain from actually being translated into perceived end-user benefit. Several different techniques have evolved to maximize the performance of business analysis queries in a warehouse, including: I Specialized indexing schemes. Typical business analysis queries involve a subset of the data in the warehouse, selected on the basis of dimension values. For example, a comparison of this month s and last month s results involves only two of the 36 months of data in the example warehouse. Specialized indexing schemes have been developed to allow very rapid selection of the appropriate rows from the fact table and joining to the dimension tables. Several of these involve bitmap techniques, where the individual possible values for a dimension (or a combination of dimensions) are each assigned a single bit in an index value. Rows meeting a selection criteria can be very rapidly identified by bitwise logical operations, which a computer system can perform more rapidly than value comparisons. I Parallel processing techniques. Business analysis queries can often be broken up into parts that can be carried out in parallel, to reduce the overall time required to produce the final results. In a query joining four warehouse tables, for example, the DBMS might take advantage of a two-processor system by joining two of the tables in one process and two others in another. The results of these intermediate joins are then combined. Alternatively, the workload of processing a single table in the query might be split and carried out in parallel for example, assigning rows for specific month ranges to specific processes. The use of multiprocessor systems in these cases is quite different than for OLTP databases. For OLTP, the focus of multiprocessor operations is to increase overall throughput. For warehousing, the focus is usually the improvement in overall execution time in response to a single complex query. I Specialized optimizations. When faced with a complex database query involving selection criteria and joins, the DBMS has many different sequences in which it can carry out the query. The optimizer for an OLTP database tends to benefit from the assumption that foreign key/primary key relationships should be exercised early in its processing, since they tend to cut down dramatically on the number of rows of intermediate results. The optimizer for a warehousing database may make a quite different decision, based on information accumulated during the load process about the distribution of data values within the database.

Data warehousing is a rapidly growing part of the market for SQL-based relational databases and is one with a set of specialized requirements: I Warehouse databases are optimized for the workload of typical business analysis queries, which is quite different from OLTP workloads. I Specialized utility programs provide high-performance loading of the warehouse and analysis tools for taking advantage of warehoused data. I Specialized database schema structures, such as the star schema, are typically used in warehouse applications to support typical business analysis queries and optimize performance. I SQL extensions are frequently used to support typical business analysis queries involving time series and trend analysis, rank orderings, and time-based comparisons. I Careful design of a large warehouse is required to provide the correct balance between load-time performance and runtime performance.
