Type system is the implementation of objects or models (types) in a model-driven architecture . Types represent a data model of the object and its properties, and can be extended or mixed with other type definitions to create more complex data structures. Canonical schemas define the data structure and relationships of each type, and canonical transforms define the steps required to load data from the source system into the canonical schema (type). Using a type system allows for a standard data model that is consistent and uniform across all applications, abstracting the complexity of the underlying data and processes. If application logic is designed and written against the type system, then individual data sources and services can be connected to the type system without requiring changes to the applications built on top. This abstraction layer simplifies the overall implementation process and reduces the complexity of connecting all the different data sources and use cases.

A programming language consists of a system of allowed sequences of symbols (constructs) together with rules that define how each construct is interpreted. For example, a language might allow expressions representing various types of data, expressions that provide structuring rules for data, expressions representing various operations on data, and constructs that provide sequencing rules for the order in which to perform operations.

A simple type system for a programming language is a set of rules that associates a data type (for example, integer, floating point, string) with each term (data-valued expression) in a computer program. In more ambitious type systems, a variety of constructs, such as variables, expressions, functions, and modules, may be assigned types.
