CMM Capability Maturity Model (Capability Maturity Model)
CMM is used to evaluate a set of standards for software development capabilities, businesses can by using this method to improve software quality and improve software productivity. CMM allow enterprises to be able to reach a product development process and the budget request, to achieve Time-to-market, Cost saving and High Quality goals.
CMM is a software development process standard for software development can be said to be kinds of quality assurance, as ISO is the same organization and management of quality assurance. Under subdivision, CMM /CMMI. Is divided into five, from the first level (Level 1) to the fifth level (Level 5), respectively, process management software company marked the competitiveness of the degree of an application can be included as long as eliminate the need for review, but by fourth grade To do quality control, 5th grade was the best, then it can prevent defects.
CMM is the Carnegie Mellon University's Software Engineering Institute (SEI) in 1986, have developed, is the world's most popular and practical software development and design of the recognized standards and software process maturity level certification standards, and Software production has become an indispensable tool is necessary to enter the international market permits.
CMMI Capability Maturity Model Integration (Capability Maturity Model Integrated)
CMMI was developed by the U.S. Software Engineering Institute's software development capability evaluation, formerly known as the Capability Maturity Model (CMM; Capability Maturity Model).
In 1986, Carnegie Mellon University's Software Engineering Institute (SEI; Software Engineering Institute) to accept the U.S. Department of Defense commissioned the development of a set used for evaluating the organization, department or team level software project development capability evaluation model, while rigorous software development process to provide a comprehensive framework and description of this model is a world-renowned model CMM
After 20 years of evolution, SEI extension of CMM in recent years, meaning and applicability, development can be used for systems engineering, software engineering, hardware and software systems integration, product development and process integration, vendor management applications on top of new model-CMMI, The CMMI covers not only the original CMM model, will be engineering standards EIA731, the international quality assurance standard definition of rolled ISO mode.
CMMI not only require companies to follow standards into systems engineering and software project to improve the development process in order to improve software productivity and quality, but also to provide a complete evaluation framework. At this stage in the international software market, the majority of companies have been evaluating whether the adoption of CMMI, as OEM software can undertake an important condition for the project. CMMI for systems development and management processes to build calendar strict specifications, while the ability of a team, divided into five maturity levels, up to fifth grade (Level 5). Currently there are around more than 700 units through the CMMI certification, through the fifth grade certification is still a minority, mostly concentrated in the United States, India, China and Russia.
COBOL Common Business Oriented Language
COBOL is a structured high-level programming language, its characteristics are stable and well suited as a development of business logic and processing large amounts of data use.
U.S. Department of Defense in late 1950, in CODASYL (COnference on DAta SYstem Language, Information System Language Conference) to prepare a COBOL language. This programming language is a programming language in the American business closest to the standard one, while the American National Standards Institute in 1968, will standardize COBOL, and in 1974 announced a revised version known as ANSI-COBOL.
Birth has a 43-year history, COBOL has been in line with industry standards, such as were made in recent years, the standard ANSI and ISO certification. With the changes in the environment, COBOL faced with the challenge of rising star, but also constantly adding new features, the biggest change is to be consistent with object-oriented (object-oriented) programming language concepts.
Born in the mainframe era of the original programming language COBOL, in recent years, will be gradually into the Web Services area, in companies in the Micro Focus launched. NET Server operating system on the implementation of the compiler will be followed in Visual Studio. NET Common Language Runtime Environment Library (Common Language Runtime, CLR) in the development of the program.
Collocation Hosting
Personal or business web site hosting on the ISP, or network traffic assembly point hosted by hand, in addition to the bandwidth of large pages to download and solve the problem of slow data transmission, the host who can provide professional web hosting engineering team can monitor the maintenance of client's website.
Often have to provide hosted backbone network, such as T1 or T3 lines, can be quickly connected client hosts at home and abroad the Internet. |
