Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

Batch Processing
Computerized batch processing is a method of running software programs called jobs in batches automatically. While users are required to submit the jobs, no other interaction by the user is required to process the batch. Batches may automatically be run at scheduled times as well as being run contingent on the availability of computer resources. History The term "batch processing" originates in the traditional classification of methods of production as job production (one-off production), batch production (production of a "batch" of multiple items at once, one stage at a time), and flow production (mass production, all stages in process at once). Early history Early computers were capable of running only one program at a time. Each user had sole control of the machine for a scheduled period of time. They would arrive at the computer with program and data, often on punched paper cards and magnetic or paper tape, and would load their program, run and debug it, and carry off thei ...

Installation (computer Programs)
Installation (or setup) of a computer program (including device drivers and plugins), is the act of making the program ready for execution. Installation refers to the particular configuration of software or hardware with a view to making it usable with the computer. A soft or digital copy of the piece of software (program) is needed to install it. There are different processes of installing a piece of software (program). Because the process varies for each program and each computer, programs (including operating systems) often come with an ''installer'', a specialised program responsible for doing whatever is needed (see below) for the installation. Installation may be part of a larger software deployment process. Installation typically involves files containing program code and data being copied/generated from the installation to new files on the local computer for easier access by the operating system, creating necessary directories, registering environment variables, providi ...

Cullinet Software
Cullinet was a software company whose products included the database management system IDMS and the integrated software package Goldengate. In 1989, the company was bought by Computer Associates. Cullinet was founded in Arlington, Massachusetts and later headquartered at 400 Blue Hill Drive in Westwood, Massachusetts. History Early years The company was started by John Cullinane and Larry English in 1968 as Cullinane Corporation. Their idea was to sell pre-packaged software to mainframe users, which was at that time a new concept in an era when enterprises only used internally developed applications or the software that came bundled with the hardware. Rather than write its own products, Cullinane approached IT (information technology) departments (at that time called Data Processing departments) of major enterprises, particularly banks, to identify internally developed applications that he felt had potential to be productized and licensed to others. However, it proved difficult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McCormack & Dodge
Dun & Bradstreet Software Services, often shortened to D&B Software, was formed by the merger of the Management Science America and McCormack & Dodge companies in June 1990, under the ownership of the Dun & Bradstreet corporation. In 1982, ''McCormack & Dodge'' was described by ''The New York Times'' as "one of the nation's top three financial software concerns." Overview After the merger, the separate company headquarters, located in Massachusetts and Atlanta, were retained with videoconferencing used for communication. Originally, the merged company was a supplier of financial packages that ran on mainframe computers. In 1991, they released the client-server middleware application suite named SmartStream that ran on HP-UX. ''Smartstream'' 3.0 was introduced in early 1995. Geac In 1996, D&B Software was acquired for US$150 million by the Canadian client-server application firm Geac Computer Corporation Geac Computer Corporation, Ltd ( and ) was a producer of enterprise res ...

Venture Capital
Venture capital (VC) is a form of private equity financing provided by firms or funds to start-up company, startup, early-stage, and emerging companies, that have been deemed to have high growth potential or that have demonstrated high growth in terms of number of employees, annual revenue, scale of operations, etc. Venture capital firms or funds invest in these early-stage companies in exchange for Equity (finance), equity, or an ownership stake. Venture capitalists take on the risk of financing start-ups in the hopes that some of the companies they support will become successful. Because Startup company, startups face high uncertainty, VC investments have high rates of failure. Start-ups are usually based on an innovation, innovative technology or business model and often come from high technology industries such as information technology (IT) or biotechnology. Pre-seed and seed money, seed rounds are the initial stages of funding for a startup company, typically occurring earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 370 Assembly Language
The IBM Basic assembly language and successors is a series of assembly languages and assemblers made for the IBM System/360 mainframe system and its successors through the IBM Z. The first of these, the Basic Assembly Language (BAL), is an extremely restricted assembly language, introduced in 1964 and used on 360 systems with only 8 KB of main memory, and only a card reader, a card punch, and a printer for input/output, as part of IBM Basic Programming Support (BPS/360). The Basic Assembler for BAL was also available as part of Basic Operating System/360 (BOS/360). Subsequently, an assembly language appeared for the System/360 that had more powerful features and usability, such as support for macros. This language, and the line of assemblers that implemented it, continued to evolve for the System/370 and the architectures that followed, inheriting and extending its syntax. Some in the computer industry referred to these under the generic term "Basic Assembly Language" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COBOL
COBOL (; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. Many large financial institutions were developing new systems in the language as late as 2006, but most programming in COBOL today is purely to maintain existing applications. Programs are being moved to new platforms, rewritten in modern languages, or replaced with other software. COBOL was designed in 1959 by CODASYL and was partly based on the programming language FLOW-MATIC, designed by Grace Hopper. It was created as part of a U.S. Department of Defense effort to create a portable programming language for data pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SSX/VSE
Disk Operating System/360, also DOS/360, or simply DOS, is the discontinued first member of a sequence of operating systems for IBM System/360, System/370 and later mainframes. It was announced by IBM on the last day of 1964, and it was first delivered in June 1966. In its time, DOS/360 was the most widely used operating system in the world. DOS versions BOS/360 The Basic Operating System (BOS) was an early version of DOS and TOS which could provide usable functionality on a system with as little as 8 KB of main storage and one 2311 disk drive. TOS/360 TOS/360 (Tape Operating System/360, not a DOS as such and not so called) was an IBM operating system for the System/360, used in the early days around 1965 to support the System/360 Model 30 and similar platforms. TOS, as per the "Tape" in the name, required a tape drive. It shared most of the code base and some manuals with IBM's DOS/360. TOS went through 14 releases, and was discontinued when disks such as the IBM 2311 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DL/1
Data Language One (Data Language/I, DL/I, Data Language/One, Data Language/One) is the language system used to access IBM's IMS databases and its data communication system. It is implemented from many languages by making calls to a software stub, DFSLI000. This stub has entry points to handle a variety of programming languages, e.g., calling CBLTDLI from a COBOL program. This stub is linked to the calling program, passes on the request to the IMS system, and returns the results and a status code. In any full-function IMS database, the smallest element that can be retrieved is a ''segment''. Each segment is made up of ''fields'', one of which, typically, will be a key field. The segments are arranged hierarchically in the database, the highest-level segment type being a root segment. 255 different segment types, on up to 15 levels, are allowed in any database. A database ''record'' consists of a specific root segment and all its dependent child segments there is no limit to the numbe ...

VM/CMS
VM (often: VM/CMS) is a family of IBM virtual machine operating systems used on IBM mainframes System/370, System/390, zSeries, System z and compatible systems, including the Hercules emulator for personal computers. Design The heart of the VM architecture is the ''Control Program'' or hypervisor abbreviated CP, VM-CP and sometimes, ambiguously, VM. It runs on the physical hardware, and creates the virtual machine environment. VM-CP provides full virtualization of the physical machine – including all I/O and other privileged operations. It performs the system's resource-sharing, including device management, dispatching, virtual storage management, and other traditional operating system tasks. Each VM user is provided with a separate virtual machine having its own address space, virtual devices, etc., and which is capable of running any software that could be run on a stand-alone machine. A given VM mainframe typically runs hundreds or thousands of virtual machine inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
