Editor's Notes
- #6 The SDK contains all the libraries that you needed to compile web applications. It also includes the local server for testing and console client for deployment and server operations.
- #7 SAP HANA Cloud Platform Tools package enables you to:Develop and deploy Web applicationsConfigure connectivity destinationsView and configure logs and log filesManage user roles and groupsProfile Web applications locallyBuild and adapt Web applications using SAPUI5
- #8 SAP HANA Cloud Platform console client enables development, deployment and configuration of an application outside the Eclipse IDE as well as continuous integration and automation tasks.
- #9 by default, SAP HANA Cloud Platform is configured to use SAP ID service as identity provider (IdP), as specified in SAML 2.0. You can configure trust to your custom IdP, to provide access to the cloud using your own user database.
- #10 platform’s official UI framework. This is now open-source at sap.github.io/openui5/
- #11 provide relational persistence with JPA and JDBC
- #12 use it to connect Web applications to Internet, make on-demand to on-premise connections to Java and ABAP on-premise systems and configure destinations to send and fetch e-mail.
- #13 use the service to store unstructured or semistructured data in your application. It follows the OASIS Content Management Interoperability Services standards @ www.oasis-open.org
- #14 implement a logging API if you want to have logs produced at runtime
- #15 use system environment variables that identify the runtime environment of the application. Some of thevariables that you can get are hostname, region, landscape and account name.
