Welcome to Oracle Page.
Ellison took inspiration 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." 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). In 1982, RSI renamed itself Oracle Systems 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.

If you want to store a collection of data from a cursor into a table, the “BULK COLLECT INTO, FORALL INSERT” in Oracle is a friend. Instead of iterating row-by-row through the cursor, BULK processes data in a batch mode at the background. The syntax is a bit different in Oracle 10g and 11g. In the examples below, we will insert all the data from cursor into a table
In database computing, Oracle Real Application Clusters (RAC) — an option for the Oracle Database software produced by Oracle Corporation and introduced in 2001 with Oracle9i — provides software for clustering and high availability in Oracle database environments. Oracle Corporation includes RAC with the Standard Edition of Oracle Database (aka Baby RAC), but makes it an extra-charge option for the Enterprise Edition. Oracle RAC allows multiple computers to run Oracle RDBMS software simultaneously while accessing a single database, thus providing a clustered database.
SQL*Loader is a bulk loader utility used for moving data from external files into the Oracle database. Its syntax is similar to that of the DB2 load utility, but comes with more options. SQL*Loader supports various load formats, selective loading, and multi-table loads. SQL*Loader (sqlldr) is the utility to use for high performance data loads. The data can be loaded from any text file and inserted into the database.
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 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 ....
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 ....
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.
