Oracle APEX (Oracle Application Express) is a low-code application development platform developed by Oracle Corporation. APEX is used for developing and deploying cloud, mobile and desktop applications. It has a web-based integrated development environment (IDE) that includes tools such as wizards, drag-and-drop layout builders, and property ...
Remote Function Call (RFC) is the standard SAP interface for communication between SAP systems. The RFC calls a function to be executed in a remote system. [ 1 ] Remote function calls may be associated with SAP software and ABAP programming and provide a way for an external program (written in languages such as PHP , ASP , Java , C , or C++ ...
The SQL standard defines embedding of SQL as embedded SQL and the language in which SQL queries are embedded is referred to as the host language. A popular host language is C. Host language C and embedded SQL, for example, is called Pro*C in Oracle and Sybase database management systems, ESQL/C in Informix , and ECPG in the PostgreSQL database ...
In computing, the Oracle Call Interface (OCI) consists of a set of C-language software APIs which provide an interface to the Oracle database. OCI offers a procedural API for not only performing certain database administration tasks (such as system startup and shutdown), but also for using PL/SQL or SQL to query, access, and manipulate data.
Query by Example (QBE) is a database query language for relational databases. It was devised by Moshé M. Zloof at IBM Research during the mid-1970s, in parallel to the development of SQL . [ 1 ] It is the first graphical query language, using visual tables where the user would enter commands, example elements and conditions.
Also note that of the above competitors, including Essbase, all use heterogenous relational (Microsoft SQL Server, Oracle, IBM DB/2, TeraData, Access, etc.) or non-relational data sourcing (Excel, text Files, CSV Files, etc.) to feed the cubes (facts and dimensional data), except for Oracle OLAP which may only use Oracle relational sourcing.
SQLite: A VIEW named "dual" that works the same as the Oracle "dual" table can be created as follows: CREATE VIEW dual AS SELECT 'x' AS dummy; SAP HANA has a table called DUMMY that works the same as the Oracle "dual" table. Teradata database does not require a dummy table. Queries like 'select 1 + 1' can be run without a "from" clause/table name.
A transaction code is used to access functions or running programs (including executing ABAP code) [2] in the SAP application more rapidly. By entering a t-code instead of using the menu, navigation and execution are combined into a single step, much like shortcuts in the Windows OS. SAP transaction codes can be entered into the Transaction ...
