Low Code, No Code - Data Engineering Solutions 

OData (Open Data Protocol) is an  ISO/IEC approved,  OASIS standard that defines a set of best practices for building and consuming RESTful APIs. OData helps you focus on your business logic while building RESTful APIs without having to worry about the various approaches to define request and response headers, status codes, HTTP methods, URL conventions, media types, payload formats, query options, etc. OData also provides guidance for tracking changes, defining functions/actions for reusable procedures, and sending asynchronous/batch requests.

Representational state transfer is a software architectural style that was created to guide the design and development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of an Internet-scale distributed hypermedia system, such as the Web, should behave.

Low-code application development describes creating application software using visual tools and model-driven processes – instead of traditional code-based programming. It reduces the amount of hard coding needed, enabling democratized access to development and an accelerated delivery of apps. A low-code platform can range from a simplistic, free software you can use online to a sophisticated, enterprise-grade application development engine that serves the most complex and highly governed processes.

Entity Data Model (EDM): the abstract data model that is used to describe the data exposed by an OData service. An OData Metadata Document is a representation of a service’s data model exposed for client consumption.

The central concepts in the EDM are entities, relationships, entity sets, actions, and functions
