What is oracle, sap, c++, sap?
ratheesh k gave a very thorough explanation but I'll throw in one clarification.





Oracle, the company, has many products. The database is the flagship but it also has other lines of products including middleware like web application and integration server production as well as ERP software of its own.


Peoplesoft was mentioned among ERP products but it should be worth mentioning that Oracle owns and supports Peoplesoft Enterprise and the JD Edwards EnterpriseOne ERP systems as well. JDE was bought by PeopleSoft. PeopleSoft was bought by Oracle.
Reply:ORACLE:


The relational database management system (RDBMS) officially called Oracle Database (and commonly referred to as Oracle RDBMS or simply as Oracle) has become a major presence in database computing. Oracle Corporation produces and markets this software.


Larry Ellison and his friends and former co-workers Bob Miner and Ed Oates started the consultancy Software Development Laboratories (SDL) in 1977. SDL developed the original version of the Oracle software. The name Oracle comes from the code-name of a CIA-funded project Ellison had worked on while previously employed by Ampex.





C++:


C++ (pronounced /ˌsiːˌplʌsˈplʌs/) is a general-purpose programming language. C++ is regarded as a mid-level language, as it comprises a combination of both high-level and low-level language features.[1] It is a statically typed, free-form, multi-paradigm, usually compiled language supporting procedural programming, data abstraction, object-oriented programming, and generic programming.


Bjarne Stroustrup developed C++ in 1979 at Bell Labs as an enhancement to the C programming language and named it "C with Classes". In 1983 it was renamed to C++. Enhancements started with the addition of classes, followed by, among other features, virtual functions, operator overloading, multiple inheritance, templates, and exception handling. The C++ programming language standard was ratified in 1998 as ISO/IEC 14882:1998, the current version of which is the 2003 version, ISO/IEC 14882:2003. A new version of the standard (known informally as C++0x) is being developed.





SAP:


Systems, Applications, Products in data processing or SAP was originally introduced in the 1980’s as SAP R/2, which was a system that provided users with a soft-real-time business application that could be used with multiple currencies and languages. As Client-servers began to be introduced SAP brought out a server based version of their software called SAP R/3, henceforth referred to as SAP, which was launched in 1992. SAP also developed a graphical user interface, or GUI, to make the system more user friendly and to move away from the mainframe style user interface.





For the next 10 years SAP dominated the large business applications market. It was successful primarily because it was extremely flexible. Because SAP was a modular system (meaning that the various functions provided by it could be purchased piecemeal) it was an extremely versatile system. A company could simply purchase modules that they wanted and customize the processes to match the company’s business model. SAP’s flexibility, while one of its greatest strengths is also one of its greatest weaknesses that lead to the SAP audit.





There are three main enterprise resource planning (ERP) systems used in today’s larger businesses: SAP, Oracle, and PeopleSoft. ERP's are specifically designed to help with the accounting function and the control over various other aspects of the companies business such as sales, delivery, production, human resources, and inventory management. Despite the benefits of ERP’s, there are also many potential pitfalls that companies who turn to ERP’s occasionally fall into.
