Data modeling in Haskell

Headline

Basic data modeling techniques in Haskell

Description

Basic concepts of data modeling in Haskell are covered. One important aspect of data modeling is the choice between structural versus nominal typing. This distinction gives rise to Haskell's type synonyms, algebraic data types, and record types. These options are conveniently illustrated with different data models for the system:Company. Another important aspect is the choice between different modeling options for recursive data structures, specifically the use of data composition and data variation. These options map to certain idioms of using algebraic data types in Haskell. These options are conveniently illustrated with different data models for the system:Company, when departmental nesting is taken into account. Related to data modeling, there is the potential requirement of information hiding such as in the context of abstract data types. Haskell's module system supports one approach to information hiding. This is illustrated with stacks in all detail.
