Caché ObjectScript
Caché ObjectScript is a part of the Caché database system sold by InterSystems. The language is a functional superset of the ANSI-standard MUMPS programming language. Since Caché is at its core a MUMPS implementation, it can run ANSI MUMPS routines with no change. To appeal as a commercial product, Caché implements support for object-oriented programming, a macro preprocessing language, embedded SQL for ANSI-standard SQL access to M's built-in database, procedure and control blocks using C-like brace syntax, procedure-scoped variables, and relaxed whitespace syntax limitations. The language has private and public variables and globals. Global has a different meaning in this language than in most; such variables are global across routines, processes, and sessions. Thus, editing a global variable is making permanent and immediate changes to a system-universal database (which survives reboots, etc.). The scope of a private variable is the local function, the scope of a pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MUMPS
MUMPS ("Massachusetts General Hospital Utility Multi-Programming System"), or M, is an imperative, high-level programming language with an integrated transaction processing key–value database. It was originally developed at Massachusetts General Hospital for managing hospital laboratory information systems. MUMPS technology has since expanded as the predominant database for health information systems and electronic health records in the United States. MUMPS-based information systems run over 40% of the hospitals in the U.S., run across all of the U.S. federal hospitals and clinics, and provide health information services for over 54% of patients across the U.S. A unique feature of the MUMPS technology is its integrated database language, allowing direct, high-speed read-write access to permanent disk storage. This provides tight integration of unlimited applications within a single database, and provides extremely high performance and reliability as an online transaction pro ...

Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs, t ...

InterSystems Caché
InterSystems Caché ( ) is a commercial operational database management system from InterSystems, used to develop software applications for healthcare management, banking and financial services, government, and other sectors. Customer software can use the database with object and SQL code. Caché also allows developers to directly manipulate its underlying data structures: hierarchical arrays known as M technology. Description Internally, Caché stores data in multidimensional arrays capable of carrying hierarchically structured data. These are the same “global” data structures used by the MUMPS programming language, which influenced the design of Caché, and are similar to those used by MultiValue (also known as PICK) systems. In most applications, however, object and/or SQL access methods are used. Caché ObjectScript, Caché Basic or T-SQL can be used to develop application business logic. External interfaces include native object binding for C++, Java, EJB, Activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ANSI
The American National Standards Institute (ANSI ) is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide. ANSI accredits standards that are developed by representatives of other standards organizations, government agencies, consumer groups, companies, and others. These standards ensure that the characteristics and performance of products are consistent, that people use the same definitions and terms, and that products are tested the same way. ANSI also accredits organizations that carry out product or personnel certification in accordance with requirements defined in international standards. The organization's headquarters are in Washington, D.C. ANSI's operations office is located in New York City. The ANSI annual operating b ...

Programming Language
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning), which are usually defined by a formal language. Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. Definitions There are many considerations when defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Object-oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as ''methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with imper ...

Preprocessor
In computer science, a preprocessor (or precompiler) is a program that processes its input data to produce output that is used as input in another program. The output is said to be a preprocessed form of the input data, which is often used by some subsequent programs like compilers. The amount and kind of processing done depends on the nature of the preprocessor; some preprocessors are only capable of performing relatively simple textual substitutions and macro expansions, while others have the power of full-fledged programming languages. A common example from computer programming is the processing performed on source code before the next step of compilation. In some computer languages (e.g., C and PL/I) there is a phase of translation known as ''preprocessing''. It can also include macro processing, file inclusion and language extensions. Lexical preprocessors Lexical preprocessors are the lowest-level of preprocessors as they only require lexical analysis, that is, they oper ...

Embedded SQL
Embedded SQL is a method of combining the computing power of a programming language and the database Data Manipulation Language, manipulation capabilities of SQL. Embedded SQL statement (programming), statements are SQL statements written inline with the program source code, of the host language. The embedded SQL statements are parsing, parsed by an embedded SQL preprocessor and replaced by host-language call site, calls to a code library (computing), library. The output from the preprocessor is then compiled by the host compiler. This allows programmers to embed SQL statements in programs written in any number of languages such as :C programming language family, C/C++, COBOL and Fortran. This differs from SQL-derived programming languages that don't go through discrete preprocessors, such as PL/SQL and Transact-SQL, T-SQL. The SQL standards committee defined the embedded SQL standard in two steps: a formalism called Module Language was defined, then the embedded SQL standard was de ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

"Hello, World!" Program
A "Hello, World!" program is generally a computer program that ignores any input and outputs or displays a message similar to "Hello, World!". A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. "Hello, World!" programs are often the first a student learns to write in a given language, and they can also be used as a sanity check to ensure computer software intended to compile or run source code is correctly installed, and that its operator understands how to use it. History While small test programs have existed since the development of programmable computers, the tradition of using the phrase "Hello, World!" as a test message was influenced by an example program in the 1978 book ''The C Programming Language'', but there is no evidence that it originated there, and it is very likely it was used in BCPL beforehand (as below). The example program in that book prints "", and was inherited from a 1974 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Profile Scripting Language
Profile Scripting Language (PSL) is a superset of the MUMPS programming language that adds object-oriented language features. It is currently developed by Fidelity National Information Services (hereafter FIS). History PSL is a language that implements object orientated concepts such as classes, methods, encapsulation, inheritance, and strong data typing as extensions to the MUMPS language. PSL was initially conceived in December 1998 by Frank Sanchez, then President of Sanchez Computer Associates, as a transformation tool that could reverse engineer a very large and complex banking application (Fidelity National Information Services 'Profile') which was written predominantly in MUMPS. Frank Sanchez developed the original language semantics, syntax, parser, compiler and optimizer, database interface, schema binding, intrinsic classes and methods over the Christmas holiday in 1998 and early 1999. He was assisted in the development of the initial commercial releases (version 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
