Data APIs & Data Formats
Learning resources and tools.
A lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is
completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++,
- Representational state transfer (REST)
Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web
services. Web services that conform to the REST architectural style, called RESTful Web services, provide interoperability between
computer systems on the Internet. RESTful Web services allow the requesting systems to access and manipulate textual representations of
Web resources by using a uniform and predefined set of stateless operations.
- Create, read, update and delete (CRUD)
In computer programming, create, read, update, and delete (CRUD) are the four basic functions of persistent storage. Alternate words are
sometimes used when defining the four basic functions of CRUD, such as retrieve instead of read, modify instead of update, or destroy
instead of delete. CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing
information; often using computer-based forms and reports.
GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and
understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it
easier to evolve APIs over time, and enables powerful developer tools.
