Welcome to Oracle Page.


Ellison took inspiration[7] from the 1970 paper written by Edgar F. Codd on relational database management systems (RDBMS) named "A Relational Model of Data for Large Shared Data Banks."[8] He had heard about the IBM System R database from an article in the IBM Research Journal provided by Ed Oates (a future co-founder of Oracle Corporation). System R also derived from Codd's theories, and Ellison wanted to make Oracle's product compatible with System R, but IBM stopped this by keeping the error codes for their DBMS secret. Ellison co-founded Oracle Corporation in 1977 with Bob Miner and Ed Oates under the name Software Development Laboratories (SDL). In 1979 SDL changed its name to Relational Software, Inc. (RSI).[9] In 1982, RSI renamed itself Oracle Systems[10] to align itself more closely with its flagship product Oracle Database. At this stage Bob Miner served as the company's senior programmer. In 1995, Oracle Systems Corporation changed its name to Oracle Corporation.[11]

Use Microsoft Query Designer to visually design queries.

Grid Computing

Grid computing enables groups of networked computers to be pooled and provisioned on demand to meet the changing needs of business. Instead of dedicated servers and storage for each application, grid computing enables multiple applications to share computing infrastructure, resulting in much greater flexibility, cost, power efficiency, performance, scalability and availability, all at the same time.

Java

Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. More ....

Exadata

With Oracle OLAP, you no longer have to replicate data into a stand-alone, proprietary OLAP server because all of your multi-dimensional data is stored directly into the Oracle Database relational engine. Decision makers benefit from much faster access to higher quality information. More ....

Oracle Streams

Using Oracle Streams, you control what information is put into a stream, how the stream flows or is routed from database to database, what happens to messages in the stream as they flow into each database, and how the stream terminates. By configuring specific capabilities of Streams, you can address specific requirements. Based on your specifications, Streams can capture, stage, and manage messages in the database automatically, including, but not limited to, data manipulation language (DML) changes and data definition language (DDL) changes. You can also put user-defined messages into a stream, and Streams can propagate the information to other databases or applications automatically. When messages reach a destination, Streams can consume them based on your specifications.
