USAS (application)
USAS is software suite for mainframe computers, mainly intended for use in the airline, transportation, and hospitality industries. It is made up of a series of diverse and relatively complex applications written for the Unisys 1100-series, 2200-series, and Clearpath IX environments. All Nippon Airways became the first company to adopt the system in the late 1970s. Its name was originally an acronym for Univac Standard Airline Systems, but the product line is now referred to simply as "USAS". With advancements in computing, USAS is slowly being replaced in the airline industry with other software, with Unisys also developing AirCore to replace its USAS offering. Applications in the suite USAS was mainly developed for use by airlines. Check-in, reservations, and cargo operations are therefore among its main components. The original USAS applications such as USAS*RES (Reservation System), USAS*CGO (Cargo Application) were written in the early 70s and have been adapted in different ...

Business Software
Business software (or a business application) is any software or set of computer programs used by business users to perform various business functions. These business applications are used to increase productivity, measure productivity, and perform other business functions accurately. Overview Much business software is developed to meet the needs of a specific business, and therefore is not easily transferable to a different business environment, unless its nature and operation are identical. Due to the unique requirements of each business, Off-the-shelf software, off-the-shelf software is unlikely to completely address a company's needs. However, where an on-the-shelf solution is necessary, due to time or monetary considerations, some level of customization is likely to be required. Exceptions do exist, depending on the business in question, and thorough research is always required before committing to bespoke or off-the-shelf solutions. Some business applications are interact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LINC 4GL
LINC ("Logic and Information Network Compiler") is a fourth-generation programming language, used mostly on Unisys computer systems. Background LINC was originally developed as a short-cut (or template) by two programmers to reproduce and automate the production of computer applications for different companies, that had similar requirements and specifications. The requirements were similar, because the companies followed a common, generic, business model. That is, these businesses dealt with "commodities", or "parts", or "suppliers", or "customers" (named "components" in LINC terminology). These were "manufactured", or "assembled", or "purchased", or "sold" (actions termed "events" in LINC terminology). These components and events were the "interface specifications" or "ispecs" and contained the database definitions, screen designs, and business rules of the application system. LIRC (Logic and Information Report Compiler) was part of LINC and was developed to allow the programme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MASM
Microsoft Macro Assembler (MASM) is an x86 assembler that uses the Intel syntax for MS-DOS and Microsoft Windows. Beginning with MASM 8.0, there are two versions of the assembler: One for 16-bit & 32-bit assembly sources, and another (ML64) for 64-bit sources only. MASM is maintained by Microsoft, but since version 6.12 it has not been sold as a separate product. It is instead supplied with various Microsoft SDKs and C compilers. Recent versions of MASM are included with Microsoft Visual Studio. Notable applications compiled using MASM are RollerCoaster Tycoon which was 99% written in assembly language and built with MASM. History The earliest versions of MASM date back to 1981. The IBM PC Macro Assembler was released in December 1981. They were sold either as the generic "Microsoft Macro Assembler" for all x86 machines or as the OEM version specifically for IBM PCs. By Version 4.0, the IBM release was dropped. Up to Version 3.0, MASM was also bundled with a smaller companio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assembly Language
In computing, assembly language (alternatively assembler language or symbolic machine code), often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Assembly language usually has one statement per machine instruction (1:1), but constants, comments, assembler directives, symbolic labels of, e.g., memory locations, registers, and macros are generally also supported. The first assembly code in which a language is used to represent machine code instructions is found in Kathleen and Andrew Donald Booth's 1947 work, ''Coding for A.R.C.''. Assembly code is converted into executable machine code by a utility program referred to as an '' assembler''. The term "assembler" is generally attributed to Wilkes, Wheeler and Gill in their 1951 book '' The Preparation of Programs for an Electronic Dig ...

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] |
Transaction Processing
In computer science, transaction processing is information processing that is divided into individual, indivisible operations called ''transactions''. Each transaction must succeed or fail as a complete unit; it can never be only partially complete. For example, when you purchase a book from an online bookstore, you exchange money (in the form of credit) for a book. If your credit is good, a series of related operations ensures that you get the book and the bookstore gets your money. However, if a single operation in the series fails during the exchange, the entire exchange fails. You do not get the book and the bookstore does not get your money. The technology responsible for making the exchange balanced and predictable is called ''transaction processing''. Transactions ensure that data-oriented resources are not permanently updated unless all operations within the transactional unit complete successfully. By combining a set of related operations into a unit that either com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainframe Computers
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less ...

Airline Reservations System
Airline reservation systems (ARS) are systems that allow an airline to sell their inventory (seats). It contains information on schedules and fares and contains a database of reservations (or passenger name records) and of tickets issued (if applicable). ARSs are part of passenger service systems (PSS), which are applications supporting the direct contact with the passenger. ARS eventually evolved into the computer reservations system (CRS). A computer reservation system is used for the reservations of a particular airline and interfaces with a global distribution system (GDS) which supports travel agencies and other distribution channels in making reservations for most major airlines in a single system. Overview Airline reservation systems incorporate airline schedules, fare tariffs, passenger reservations and ticket records. An airline's direct distribution works within their own reservation system, as well as pushing out information to the GDS. The second type of direct dist ...

UNISYS
Unisys Corporation is a global technology solutions company founded in 1986 and headquartered in Blue Bell, Pennsylvania. The company provides cloud, AI, digital workplace, logistics, and enterprise computing services. History Founding Unisys’ history dates back to 1873 with E. Remington & Sons and the introduction of the first commercially viable typewriter to use the QWERTY keyboard layout. Over a hundred years later, the company became known as Unisys in 1986 through the merger of Mainframe computer, mainframe corporations Sperry Corporation, Sperry and Burroughs Corporation, Burroughs, with Burroughs buying Sperry for $4.8 billion. The new company's name was chosen from over 31,000 submissions in an internal competition when Christian Machen submitted the word "Unisys", which was composed of parts of the words "united", "information", and "systems". The merger was the largest in the computer industry at the time and made Unisys the second-largest computer company wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
