Get the original essay The history of ERP began with the first attempts at calculating machines in the 1940s. Enterprise Resource Planning (ERP) emerged from a joint effort in the early 1960s between JI Case, the manufacturer of tractors and other construction equipment, and its partner IBM. Material requirements planning or MRP is the initial effort. This application software serves as a material planning and scheduling method for complex manufactured products. 1970s: Early MRP solutions are bulky, clunky and expensive. They require significant technical staff to support the mainframe computers on which they run. 1972: Five engineers in Mannheim, Germany, create the company SAP (Systemanalyse und Programmentwicklung). The purpose of creating SAP is to produce and market standard software for integrated business solutions. 1975 Richard Lawson, Bill Lawson and business partner John Cerullo launch Lawson Software. The founders see the need for pre-packaged enterprise technology solutions as an alternative to custom enterprise software applications. 1976 In the manufacturing industry, MRP (Material Requirements Planning) becomes the fundamental concept used in production management and control. 1977: Jack Thompson, Dan Gregory and Ed McVaney form JD Edwards. Each founder uses part of their name to create the company's nickname. Larry Ellison creates Oracle Corporation. 1978: Jan Baan establishes The Baan Corporation to provide financial and administrative consulting services. 1979: Oracle offers the first commercial SQL relational database management system. 1980: JD Edwards begins to focus on IBM System/38 in the early 1980s. MRP (Manufacturing Resources Planning) evolves into MRP-II as a more accessible extension to shop floor and distribution management activities. 1981: Baan begins using Unix as its primary operating system. 1982: Baan delivers its first software product. JD Edwards focuses on the IBM/38 system. 1983: Oracle offers both a VAX mode database as well as a database entirely written in C (for portability). 1984: Baan shifts the focus of its development to manufacturing.1985: JD Edwards is recognized as a leading provider of application software for the successful IBM AS/400 computer, a direct descendant of the System/38.1987: PeopleSoft is founded by Dave Duffield and Ken Morris in 1987.1988: The System Human Resources Management System (HRMS) from PeopleSoft is developed. 1990: Baan software is deployed in 35 countries via indirect sales channels. The term ERP (Enterprise Resource Planning) was coined in the early 1990s when MRP-II was expanded to cover areas such as engineering, finance, human resources and project management. 1991: PeopleSoft opens offices in Canada. This paves the way for their presence in Europe, Asia, Africa, Central and South America and the Pacific region. 1995: Baan has more than 1,800 customers worldwide and more than 1,000 employees. 1999: JD Edwards has more than 4,700 customers with locations. in more than 100 countries. Oracle has 41,000 customers worldwide (16,000 in the United States). PeopleSoft software is used by more than 50 percent of the human resources market. SAP is the world's largest business-to-business software company and the world's fourth-largest independent software vendor. SAP employs more than 20,500 people in more than 50 countries. To date, more than 2,800Baan's enterprise systems have been implemented in approximately 4,800 locations worldwide. 2001 – September 11: Occurs, leading to a drop in demand for new ERP systems. 2002: Most ERP systems upgrade their products to become “Internet-enabled”. » so that customers around the world can have direct access to the supplier's ERP system. 2004: Service-oriented architecture (SOA) becomes a standard that ERP vendors are working toward. This software architecture allows different systems to communicate with each other. 2003-2005: Industry consolidation occurs: Oracle - E-Business Suite, JD Edwards, Peoplesoft and Seibel Microsoft - Navision, Axapta, Great Plains and SolomonInfor - Baan, Mapics and a host of other productsSage - Best software is acquired CURRENT WORKConsolidations continue and key players (SAP, Oracle, Infor and Microsoft) continue to develop their products. The next phase of ERP systems will be merged products, including Oracle Fusion. Additionally, a new entry in ERP history will be made as vendors move to cloud computing. For a list of many major ERP solutions, please see our ERP software directory. PROPOSED WORKSaaS (Software-as-a-service) is a web-based software services model. This software model can provide underlying and corresponding infrastructure support for a variety of applications, including completing the initialization of the corresponding service, maintaining the operating environment, such as data backup. Companies therefore do not need to recruit IT staff, build a computer room and purchase hardware and software. They only have to pay the rent and, thanks to the Internet, they can use their own applications, such as sales management systems, video conferencing systems, messaging systems. In this way, through the Internet, users will be able to benefit from appropriate hardware, software and maintenance services, and will be entitled to benefit from increasing services. In short, if businesses adopt SaaS, they can reduce the costs of IT products, technologies and maintenance operations, especially for small and medium-sized businesses, which is an important way to quickly build applications. At the same time, the way of collecting rent for software and service providers is also beneficial. They can predict their revenues and more accurately formulate their own development strategies and new product development. SaaS allows companies not to spend too much funds on information construction, even not full business deployment and analysis before information implementation, which can significantly reduce costs. The cost of enterprise information construction and the application of the threshold can therefore encourage more enterprises to enjoy the benefits of lower risk to achieve information management. Precisely, SaaS can solve the problem that most of our companies cannot obtain information quickly due to lack of funds, limited capacity taking risks. The design of the ERP system is based on the use of the popular Django framework and the MVC pattern. The use of this framework is designed to realize an ERP system based on SOA. Selecting the appropriate development framework and platform in the system implementation process is a very important part. The Django framework is a common platform in building SOA. The multi-level architecture model and the..
