Schemagebunden

Schemagebunden is a term used in information technology to describe data objects or software artifacts that are bound to a predefined schema. In Swedish IT literature, it often refers to structures whose existence or behavior is constrained by the rules and definitions of a schema, such as a database schema, an XML schema, or a JSON schema. When an object is schemagebunden, its shape, types, and allowed relations are enforced by the schema, providing consistency and interoperability across systems.

Etymology and usage context: the word is formed from schema, borrowed from Latin and used in many technical languages, and bunden, meaning bound or tied. The concept is particularly prominent in database design, data interchange, and model-driven development, where schemas act as contracts that objects must adhere to. In practice, the term is often encountered in Swedish discussions of SQL Server and similar platforms, where binding an object to a schema may affect how it can be modified or extended.

In relational databases, schemagebunden objects may include views, functions, or procedures defined with a binding to the underlying schema. A schemagebunden view, for example, restricts changes to the referenced tables that would invalidate the view, and may offer performance or integrity benefits by enabling certain optimizations. However, it can also limit maintenance operations, making schema evolution more complex.

Beyond databases, schema binding is used in data exchange and validation, where documents or messages are required to conform to a defined schema, ensuring consistency and reducing integration issues.
