What is OData?
OData stands for Open Data Protocol. It defines best
practices for building and consuming RESTful APIs and standard ways to access
resources.
OData is a REST based protocol for updating and querying
the data.
OData is ‘SQL for Web’
Why OData?
By using OData, you can focus on building business logic
while developing REST APIs without worrying about the approaches to define
request and response headers, status codes, HTTP methods, URL conventions,
media types, payload formats and query options etc.
What can you do with
OData?
a.
Metadata: a machine-readable description of
the data model exposed by a particular service.
b.
Data: sets of data entities and the
relationships between them.
c.
Querying: requesting that the service perform
a set of filtering and other transformations to its data, then return the
results.
d.
Editing: creating, updating, and deleting data.
e.
Operations: invoking custom logic
f.
Vocabularies: attaching custom semantics
