<ul><li>OData (Open Data Protocol) is a protocol for querying and manipulating data over RESTful APIs, developed by Microsoft.</li><li>Key features of OData include querying data, CRUD operations, batch requests, metadata information, and pagination.</li><li>To enable OData in an ASP.NET Core Web API, install the OData package and configure it in Program.cs.</li><li>IEdmModel in OData defines the data model structure and is essential for OData route configuration in ASP.NET Core.</li><li>OData queries can be performed using $filter, $orderby, $select, $expand, etc., once IEdmModel is configured.</li><li>Pagination in OData is supported using $top and $skip to limit the number of records returned.</li><li>$expand in OData is used to fetch related data, similar to JOINs in SQL.</li><li>Batch requests in OData allow multiple API calls in a single HTTP request, reducing network overhead.</li><li>OData offers advantages over standard REST APIs in terms of querying data, pagination, metadata, and batch requests.</li><li>Security in OData APIs can be implemented using authentication, authorization, rate limiting, and restricting unused query options.</li></ul>
