SAP OData & Gateway Masterclass - Build Enterprise Services

Explore the entity data model as a blueprint that structures data into meaningful objects, enabling a common server–client language via the schema, container, entity sets, function imports, and metadata document.

Entity types are blueprints for objects, detailing fields, data types, and a unique key; entity sets are logical containers tied to a type that store records.

Examine the properties and their data types to enable backend to frontend communication. Define unique keys, including composite keys, and complex types like address to build a robust data model.

Define associations and navigation properties to link entity types, establish cardinality, and enable single, efficient requests for related data across enterprise datasets.

Explore function imports to trigger custom logic via simple web endpoints, bridging standard data models with customized operations. Learn how get and post variants return data and handle input parameters.

Master the service development workflow—from the project creation phase through modeling and implementation. Define entity types, properties, and relationships, then register and activate the gateway service.

Understand how the service metadata document acts as the contract for your data service, detailing entity sets, properties, relationships, and data types in a machine-readable format that updates automatically.

Register your service to the gateway, assign a system alias, and activate it to enable external access. Verify via a metadata check that the gateway can talk to the backend.

Master the model provider to define entities and metadata, and the data provider to implement backend data access, with extension classes enabling custom logic and metadata-based gateway validation.

Identify and manage services with the service maintenance tool, activating, grouping, testing, and monitoring their lifecycle while ensuring governance, security, and reliable routing to back-end systems.

Define create, read, update, delete, and query (QoV) operations and map them to the data provider class to enable data discovery and secure, efficient enterprise OData services.

Master data retrieval by using $filter to refine results on the server and $select to return only needed fields, reducing payload and boosting performance in enterprise services.

Master how $expand bundles related entities into a single response to boost performance in enterprise services, while $value returns only the raw content of a property for efficient data access.

Master the $top, $skip, and $orderby parameters to control data volume and sequence, enabling paging, sorting, and targeted slices for high-performance enterprise apps.

Compare client-side and server-side paging to keep apps fast with large data. Learn how server-side paging fetches only needed records, reduces network traffic, and enhances scalability.

Master deep inserts to package a parent and its children in a single atomic request, ensuring data integrity and fewer network calls, while handling media link entries for binary content.

Harness batch processing with the $batch endpoint to group updates, creates, and deletes into a single multi-part mixed request, using change sets to ensure all operations succeed or fail together.

Learn how the lost update problem arises when multiple users edit the same record. Explore how ETag and the if-match header enable optimistic concurrency checks to prevent overwrites.

Learn how gateway authentication verifies users, enforces role-based authorization, and uses user mapping and tokens to protect data in transit with TLS.

Learn to boost OData and gateway service performance by minimizing data transfer, using selective properties and filters, optimizing backend queries with caching and indexing, and applying server-side paging and batching.
