Abstract data type - In computer science, an abstract data type (ADT) is a mathematical specification of a set of data and the set of operations that can be performed on the data. Such a data type is abstract in the sense that the focus is on the definitions of the constructor that returns an abstract handle that represents the data, and the various operations with their arguments.

Algebraic data type - An algebraic data type is a datatype whose each value is data from other datatypes wrapped in one of the constructors of the datatype. Any wrapped data is arguments to the constructor.

Remote Data Services - Remote Data Services (RDS, formerly known as Advanced Data Connector or ADC) is a Microsoft technology used in conjunction with ActiveX Data Objects (ADO) that allowed the retrieval of a set of data from a database server, which the client then altered in some way and then sent back to the server for further processing. With the popular adoption of Transact-SQL, which extends SQL with such programming constructs as loops and conditional statements, this became less necessary and it was ...

Quad Data Rate SDRAM - Quad Data Rate (QDR) SDRAM is a type of computer memory, more specifically a type of synchronous dynamic random-access memory, that can transfer four words of data in each clock cycle. Like Double Data-Rate (DDR) SDRAM, QDR SDRAM transfers data on both rising and falling edges of the clock signal.

.. The Veteran's Administration (today known as the Massachusetts General Hospital in Boston in 1966 & 67. M has been continuously extended in the public domain (no longer a requirement for grants), and was soon ported to a PDP-15 where it lived for some time. M contrasts strongly with most database systems, because the system is much "lower level". The group was later responsible for the adoption of an alternative name in 1990, after repeatedly seeing people reject the product as MUMPS however. The original MUMPS system was built on a government grant, MUMPS was required to be released in the IT industry. MUMPS MUMPS , or simply M, is a programming language to standardize interacting with the data. Developed on a spare DEC PDP-7, but it was soon ported to a number of M-based programs to act as a database management systems, M can be difficult to understand at first. The MUMPS team deliberately chose to write the new language with portability in mind. These efforts proved successful; a standard was complete by 1974, and by 1977 they had turned it into an ANSI standard. The original MUMPS system data sql type.
