Why would one use OData over HTTP and what are the benefits and disadvantages of using it? Also what does OData expose?

 One would use OData over HTTP for several reasons. OData provides a standardized protocol for exposing, accessing, and manipulating data over the web, making it easier to integrate and consume data from various sources. Some benefits of using OData include:

  1. Uniform Interface: OData offers a consistent and uniform way to interact with data, regardless of the underlying data source or technology stack.
  2. Interoperability: OData promotes interoperability between different platforms, applications, and services, enabling seamless data exchange and integration.
  3. Querying and Filtering: OData supports powerful querying and filtering capabilities, allowing clients to retrieve only the necessary data based on specific criteria.
  4. CRUD Operations: OData supports Create, Read, Update, and Delete (CRUD) operations, providing a comprehensive set of actions to manipulate data.

However, there are also some disadvantages to consider:-

  1. Complexity: Implementing and maintaining an OData service can be complex, especially for larger and more complex data models.
  2. Performance Overhead: OData adds an additional layer of abstraction, which can introduce some performance overhead compared to more direct data access methods.

OData exposes resources (such as entities and collections) from a data source, allowing clients to perform operations like querying, filtering, sorting, paging, and modifying the data. It provides a standardized way to expose the structure and capabilities of the data source, making it easier for clients to understand and interact with the data.

 Absolutely, SAP BTP is worth learning in 2025. With businesses moving rapidly toward cloud and intelligent enterprise solutions, BTP is at the center of SAP’s innovation. It allows developers to build, integrate, and extend applications in the cloud while connecting with SAP HANA, Fiori, and other services seamlessly. Learning BTP isn’t just about coding; it’s about understanding how modern SAP solutions work together.

How much coding is needed to learn SAP BTP?

 SAP BTP is designed to support both developers and business users, so the amount of coding depends on the path you choose. If you’re focusing on low-code/no-code tools like SAP Build Apps, Process Automation, or Work Zone, you can get started with minimal coding knowledge. These tools are more about designing workflows and user interfaces visually, which makes them beginner-friendly. However, if you want to dive deeper into extensions, integrations, or advanced app development, some coding is essential. Skills in JavaScript, SAP UI5, Node.js, or even ABAP on BTP can give you an edge. The good thing is that BTP provides flexibility—you can start small with no-code solutions and gradually move into coding-heavy areas as your confidence grows. I attended Anubhav Oberoy’s training on SAP BTP, and it really clarified this balance.  His approach showed when coding is required and when you can rely on BTP’s low-code capabilities. The hands-on examples made it easy to understand ho...
