-===== Omnidex SQL Engine ===== 
- 
-The Omnidex product is built around a powerful SQL engine that can process statements and take advantage of the Omnidex indexing technology. ​ This SQL engine can process traditional SQL statements, such as SELECT, INSERT, DELETE and UPDATE, and can also process a wide variety of statements to maintain the database and directly access the Omnidex indexes. ​ The Omnidex SQL Engine is based around [[dev:​sql:​home|Omnidex SQL]], a language that is based on ANSI-standard SQL and includes a number of Omnidex-specific extensions. 
- 
-The Omnidex SQL Engine automatically optimizes statements so that they use the Omnidex indexes as fully as possible. ​ As is true with most relational databases, developers do not need to refer to the indexing strategy in their statements. ​ They simply submit standard SQL statements that reference the tables and columns in the database. ​ This makes it easy to write new applications,​ and it also means existing applications that call ANSI-standard SQL will quickly receive the benefit of optimization.  ​ 
- 
-The major relational databases, such as Oracle, SQL Server and MySQL, support their own proprietary extensions to the SQL language that only work in their respective databases. ​ Omnidex supports a limited number of these proprietary extensions, such as support for some Oracle functions. ​ Generally, though, applications that use these extensions must be changed to submit ANSI-standard SQL or Omnidex extensions to be processed by Omnidex. Similarly, applications that take advantage of Omnidex extensions will only work against the Omnidex SQL Engine. 
- 
-The Omnidex SQL Engine is available through standard [[dev:​odbc:​home|ODBC]] and [[dev:​jdbc:​home|JDBC]] interfaces. ​ It can also be accessed interactively in the Omnidex Administrator and in the console program, OdxSQL.  ​
