Record type
A record type is a classification describing the structure, kind, and semantic role of records within a data format or system.
Building User-Friendly DSLs
A construct representing a named record with a collection of attributes in the domain-specific language.
- How it is used
- Defines named domain data shapes that business rules reference and the Runtime can represent.
- How deep it goes
- Explains record type properties and AST projection, then extends the concept with editable business rules.
- Examples
- Uses a Rental record type with attributes and renders it through HTML, CSS, and JSX Projection code.
- What you can do after
- Build it from scratch by modeling record type settings, projecting attributes, and adding a business-rules collection.
Data-Oriented Programming: Reduce software complexity
A record type is a classification identifying the kind of entity represented by a record, such as a member or librarian.
- How it is used
- Uses record types to decide whether library data represents a member or librarian.
- How deep it goes
- Explains index-based classification and member-specific fields, rather than formal runtime type machinery.
- Examples
- Demonstrates a library UserManagement record, librarian lookup, VIP membership, and member feature fields.
- What you can do after
- Apply via map lookups and field checks to classify users without requiring an explicit type field.
