Learn SAP® CAPM (Cloud Application Programming Model)

Overview

• Learn and Understand the NodeJS based CAPM Model from SAP® for Cloud App Development With CDS End-to-End in SAP® BTP/Cloud Foundry

• Start with Basic End-to-End CAPM App Development and Gradually Understanding Complex Scenarios and Features

• This section starts slowly with basics and progressively advances on crucial concepts required to work with CAPM. In the consecutive Levels of CAPM, we will see the depth of DB, Service, CDS, Annotations, and Tools at our disposal. This week should give you an end-to-end spectrum and strong foundation to start your Journey with New SAP® CAPM.

Details of What You Will Learn in this Course:

In Section 1:

In this section, we have covered Level 1 where we will see a Basic End-to-End CAPM App from Scratch.

• First, we will start with a short theory to understand what to expect

• Then we will set our Development environment for CAPM dev and install NPM Repo to use CDS Command from npm sap registry

• Then we will get starting with creating some Hello World Service App and testing in local env

• After that, we will take our usecase of the LMS system and create a simple Student entity and create CSV sample data

• We will then create a simple Service to read all the Student data. In this case, we will use sqlite3 DB to test results locally

• After that, we will add Annotation to our Student entity so, in Fiori® Preview we can see Data in App

• Once we have developed our services, we will go and separate UI part of the code and create a UI5 App that contains information about routes, uses data model from the service and adds UI annotations to the service

• After that we will test the end-to-end scenario locally

• Now, it is time to launch our app in SAP® Cloud Foundry. We will create an HDI container and this time with the DB artifacts we will see our structure get created and also data get added.

• We will push the final application into the cloud and test the final Fiori® Launchpad and App.

This section starts slowly with basics and progressively advances on crucial concepts required to work with CAPM. In the consecutive Levels of CAPM, we will see the depth of DB, Service, CDS, Annotations, and Tools at our disposal. This week should give you an end-to-end spectrum and a strong foundation to start your Journey with New CAPM.

In Section 2:

In this section of Level 2, we will see NodeJS CRUDQ Service in CAPM, Async Functions and Debugging.

• How to implement CDS based service with CDS QL

• How to work with an event like on, before and after in service and usage

• Learn Async Code with Promise and with Async & Await

• Learn how to use CDS transactions to execute single or multiple queries

• How to handle the Promise of CDS transaction with reject and resolve status

• Implement Update, Delete, Select, Query and Insert with debugging

• Testing in postman, in the browser, in the console and on debugging screen using VS code

• How to extend already implemented service and add more functionality like changing URL pattern, or changing return structure with CDS code.

This week will give you a firm foundation on basic NodeJS code which is essential to master when you work with SAP® CAPM based project development.

In Section 3:

In this Week of Learn SAP® Cloud Platform, we have covered Level 3 of CAPM(SAP® Cloud Application Programming Model). Where you will find:

• Data Modeling with CDS(Core Data Service)

• How to Model Data with Association using our LMS(Learning Management System) Example

• How to use UI Annotations to represent Data in UI5 App Out of box Navigation in APIs

• Using Navigation and Routes in CAPM UI5 App

• Using UI Annotation to showcase Navigation Data
