The CAP Cookbook
Guides and Recipes for Common Tasks
The following figure illustrates a walkthrough of the most prominent tasks within CAP's universe of discourse (aka scope). The guides contained in this section provide details and instructions about each.
- Domain Modeling
- Most projects start with capturing the essential objects of their domain in a respective domain model. Find here an introduction to the basics of domain modeling with CDS, complemented with recommended best practices.
- Providing Services
- This guide introduces how to define and implement services, leveraging generic implementations provided by the CAP runtimes, complemented by domain-specific custom logic.
- Consuming Services
- Learn how to use uniform APIs to consume local or remote services.
- CAP provides intrinsic support for emitting and receiving events. This is complemented by Messaging Services connecting to message brokers to exchange event messages across remote services.
- Learn about CAP's intrinsic querying capabilities, which allows clients to request the exact data they need, and are key enablers for serving requests automatically.
- This guide will help you to learn about defining, providing, implementing, deploying, and publishing services — so it's about _Service Providers_ in general.
- This guide explains how to restrict access to data by adding respective declarations to CDS models, which are then enforced in service implementations.
- Localization, i18n
- Guides you through the steps to internationalize your application to provide localized versions with respect to both Localized Models as well as Localized Data.
- Localized Data
- This guide extends the localization/i18n of static content, such as labels or messages, to serve localized versions of actual application data.
- Temporal Data
- CAP provides out-of-the-box support for declaring and serving date-effective entities with application-controlled validity, in particular to serve as-of-now and time-travel queries.
- Media Data
- CAP provides out-of-the-box support for serving media and other binary data.
- Data Privacy
- CAP helps application projects to comply with data privacy regulations using SAP Business Technology Platform (BTP) services.
- Introducing the fundamental concepts of multitenancy, underpinning SaaS solutions in CAP. It describes how to run and test apps in multitenancy mode with minimized setup and overhead.
- Learn here about instrinsic capabilities to extend your applications in verticalization and customization scenarios.
- Learn here about the essential steps to deploy a CAP application to SAP BTP Cloud Foundry environment, and options to operate them.
