Algebraic data type — In computer programming, particularly functional programming and type theory, an algebraic data type (sometimes also called a variant type[1]) is a datatype each of whose values is data from other datatypes wrapped in one of the constructors of… … Wikipedia
Abstract data type — In computing, an abstract data type (ADT) is a 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 it is independent of various concrete implementations. The… … Wikipedia
Generalized Algebraic Data Type — Generalized Algebraic Data Types are generalizations of the algebraic data types of Haskell and ML, applying to parametric types.With this extension, the parameters of the return type of a data constructor can be freely chosen when declaring the… … Wikipedia
Real data type — A real data type is a data type used in a computer program to represent an approximation of a real number.Because the real numbers are not countable, computers cannot represent them exactly using a finite amount of information.Most often, a… … Wikipedia
Ordinal data type — In computer programming, an ordinal data type is a data type with the property that its values can be counted. That is, the values can be put in a one to one correspondence with the positive integers. For example, characters are ordinal because… … Wikipedia

Data structure alignment — is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding. When a modern computer reads from or writes to a memory address, it will do this in word sized … Wikipedia
Type inference — Type inference, or implicit typing, refers to the ability to deduce automatically the type of a value in a programming language. It is a feature present in some strongly statically typed languages. It is often characteristic of but not limited to … Wikipedia
Data profiling — is the process of examining the data available in an existing data source (e.g. a database or a file) and collecting statistics and information about that data. The purpose of these statistics may be to: Find out whether existing data can easily… … Wikipedia
