This proposal uses Formula, a model finding and design space exploration tool that is based on Algebraic Data Types (ADT) and Constraint Logic Programming (CLP). The main contributions of this paper are twofold: (1) providing a more complete set of patterns for defining commonly occurring types...
The goal of this article is to show that, in the context of XML data processing, information conveyed by schema or XML types is a powerful component to deploy optimization methods. We focus on the one hand on recent work developed -for optimizing query and update evaluation for main-memory ...
Simulink data types with unspecifiedMinandMaxcorrespond to AUTOSAR application data types with full-range constraints. For example: On import, if thePhysConstrvalues on an application data type match the full lower and upper limits in theInternalConstrfor the associated implementation data type, the ...

functions andoperatorsmust be explicitly defined because they will not automatically acquire the functions and operators of the source data type. In contrast, weakly typed UDTs operate in the same way as the underlying source data type. That said, users can define certain constraints on the values...

User-defined integrity.These are additional rules and constraints that are implemented in accordance with the organization's specific needs and aren't otherwise covered by the first three integrity types. Physical and logical integrity are defined separately but can often be related. For example, a ...
Constraints on CSS and Elasticsearch CDM supports automatic creation of indexes and field types. The index and field type names can contain only lowercase letters. You cannot modify the field type under an index after it is created, but only create another field. ...
