In the context of SAP HANA Deployment Infrastructure (HDI), anHDI Containeris a dedicated, isolated schema in the SAP HANA database that stores and manages database objects such as tables, views, procedures, and other artifacts. HDI Containers are used tosupport multi-target applications (MTAs) and enable developers to manage database objects in a structured and modular way.
HDB Module (B):AnHDB moduleis a development object within the SAP Web IDE for SAP HANA or SAP Business Application Studio. It contains the database design-time artifacts (e.g.,.hdbtable,.hdbview,.hdbsynonym) that define the structure and logic of the database objects. When you build an HDB module, it triggers the creation of an HDI Container if one does not already exist. The HDI Container is then populated with the runtime objects generated from the design-time artifacts defined in the HDB module.
Key Points:
The HDB module is part of a Multi-Target Application (MTA) project.
It uses the HDI Deployer service to deploy the design-time artifacts into the HDI Container.
The HDI Container ensures isolation and versioning of database objects, making it suitable for modern application development practices.
Why Not the Other Options?
Space (A):Aspaceis a concept in Cloud Foundry environments where applications and services are deployed. While spaces are used to organize and isolate resources, they are not directly related to generating an HDI Container. Spaces host applications and services but do not define the database objects required for an HDI Container.
Package (C):In SAP HANA, apackageis a folder-like structure used to organize development objects in the SAP HANA repository. However, packages alone do not generate HDI Containers. They are used in the classic repository-based development model (XSA or XS Classic), whereas HDI Containers are associated with the newer HDI-based development model.
SQL Script Procedure (D):ASQL script procedureis a database artifact used to define procedural logic in SQL. While SQL script procedures can be deployed into an HDI Container, they are not responsible for generating the container itself. The container must already exist before deploying such artifacts.
Development Object Required to Generate an HDI Container:
SAP Data Engineer - Data Fabric Context:In theSAP Data Engineer - Data Fabriclandscape, HDI Containers play a crucial role in enabling modular and scalable data management. They allow developers to create isolated environments for different applications or tenants, ensuring data security and consistency. By leveraging HDB modules, developers can define and deploy database objects in a structured manner, aligning with modern DevOps practices.

SAP HANA Developer Guide for SAP HANA XS Advanced: Explains the role of HDB modules and HDI Containers in application development.
SAP Business Application Studio Documentation: Provides guidance on creating and building HDB modules in the context of MTAs.
SAP Learning Hub: Offers training on SAP HANA development, including HDI and MTA concepts.
By selectingB (HDB module), you ensure that the correct development object is identified for generating an HDI Container, enabling efficient database development and deployment.
