Video: Oracle SQL: Use Analytical FunctionsDan Hotka
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
Decode the result from row_number over, partition by, order by : ROW_NUMBER « Analytical Functions « Oracle PL / SQL
The key benefits provided by Oracle's in-database analytical functions and features are: Enhanced Developer Productivity- perform complex analyses with much clearer and more concise SQL code. Complex tasks can now be expressed using single SQL statement which is quicker to formulate and maintain, re...

Note: Oracle provides two different modes for the Analytical Engine: In PE mode, the engine is suitable for use with Promotion Effectiveness. In DP mode, the engine is suitable for use in demand planning applications. For each model, this chapter indicates which engine modes that model can be...
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...
Moreover, since both f(t) and r(t) are changing monotonically with t, they are single-valued functions of s: f(s) ≡ f(t(s)) and r(s) ≡ r(t(s)). Using that ddt=f(t(s))dds in (3), we find that (3) is equivalent to...
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
After this year’s OpenWorld I ran a 1-day workshop on analytical SQL for our Data Warehouse and Big Data Global Leaders customers. This was part of the Global Leaders 'Days with Development' programme. We had a pack room at the Oracle Conference Center
