Home page for Oracle's Analytical SQL capabilities accessible in SQL. Oracle continues to expand its set of statistical functions available in Oracle 12c Database for use far beyond basic querying, supporting a wide range of features and functions: rank
Window functions, which are now a key analytical feature in the analysis of big data, were first introduced in Oracle 8i (1999) and many developers use them to manage complex big data requirements. Oracle 10g (2003) introduced the SQL Model clause, which provides a spreadsheet-like what-if ...

Window function是OLAP的查询中比较常见的SQL construct,提供了“引用临近区域元组”的语义,这种语义使得一些分析型query的编写更加简单,可以避免不必要的相关子查询结构。此外,很多系统(Oracle/PolarDB) 内部也实现了用window function做subquery unnesting,避免相关子查询的低效执行,因此window算子本身的高效实现意义就更大...

One of the proof points that I often make for using analytical SQL over more sophisticated SQL-based methods is that we have included specific optimizations within the database engine to support our analytical functions. In this blog post I am going to b
1.3.5OLAP and Data Mining Functionality Are Embedded in the Oracle Database OLAP was first defined by Dr. E. F. Codd, the father of relational databases. He stated that relational databases were not originally intended to provide data synthesis, analysis, and consolidation—functions being defined...
It describes the major differences between using scoring functions and theSAS Embedded Process publish methods to publish a model. The paper also explains how to perform in- database processing of a published model by using SAS applications as well as SQL code outside ofSAS. In addition to ...
In addition, Plugger BI seamlessly integrates with databases such as Oracle, SQL Server, MySQL, Firebird, Postgres, and Progress, as well as text files, Excel spreadsheets, and others. Thanks to the performance, high availability, and scalability of OCI, Intelecti...
Multidimensional expressions (MDX)Aside from additional MDX functions in this version of Analysis Services, the new MDX Builder utility is available for building MDX statements using drag-and-drop techniques. With the increased use of Analysis Services and the complexities of MDX syntax, the MDX Buil...
