How to Explore the SAP HANA Modeler Perspective in Eclipse

Eclipse is a popular integrated development environment (IDE) that supports various programming languages and technologies. SAP HANA Modeler Perspective is a feature of Eclipse that allows you to create, edit and manage SAP HANA views and procedures. These views and procedures can be used as sources or targets for data flows and queries in SAP HANA or SAP BW/4HANA.

In this blog post, we will explain how to explore the SAP HANA Modeler Perspective in Eclipse, which are the main components and functions of the perspective. We will also show some examples of creating and using SAP HANA views and procedures in Eclipse.

What is the SAP HANA Modeler Perspective?

The SAP HANA Modeler Perspective is a way to work with SAP HANA objects within the Eclipse environment. It consists of an editor area, where the SAP HANA object editors are placed, and the following views:

Project Explorer: It shows the projects and folders that contain the SAP HANA objects. You can create, import, export, delete and rename projects and folders here.
Properties: It shows the properties and settings of the selected SAP HANA object. You can edit the properties and settings here.
Problems: It shows the errors and warnings that occur during the validation or activation of the SAP HANA objects. You can fix the errors and warnings here.
History: It shows the history of changes made to the selected SAP HANA object. You can compare, revert or delete versions here.
SQL Console: It allows you to execute SQL statements against the connected SAP HANA system. You can view the results, messages and execution plans here.
Data Preview: It allows you to preview the data of the selected SAP HANA object. You can filter, sort, aggregate and export data here.

The SAP HANA Modeler Perspective enables you to create and edit different types of SAP HANA objects, such as:

Attribute Views: They are views that provide attributes or master data for analytical purposes. They can join multiple tables or other attribute views based on common attributes.
Analytic Views: They are views that provide measures or facts for analytical purposes. They can join one fact table with multiple attribute views based on common attributes.
Calculation Views: They are views that provide complex calculations or transformations for analytical purposes. They can combine multiple tables, attribute views, analytic views or other calculation views using graphical or SQL script logic.
Procedures: They are executable units of SQL script code that can perform complex operations on data. They can have input and output parameters, local variables, control structures and SQL statements.

The SAP HANA Modeler Perspective also allows you to manage the security and performance of the SAP HANA objects, such as:

Roles: They are collections of privileges that grant access rights to users or other roles. They can have object privileges, system privileges, analytic privileges or package privileges.
Analytic Privileges: They are special types of privileges that restrict access to data based on filters or conditions. They can be applied to attribute views, analytic views or calculation views.
Indexes: They are structures that improve the performance of data access by creating sorted copies of data columns. They can be primary indexes, secondary indexes or full-text indexes.
Partitions: They are techniques that improve the performance of data management by dividing large tables into smaller pieces based on ranges or hashes. They can be single-level partitions or multi-level partitions.

How to Explore the SAP HANA Modeler Perspective in Eclipse?

To explore the SAP HANA Modeler Perspective in Eclipse, you need to follow these steps:

Install the SAP HANA Tools for Eclipse from https://tools.hana.ondemand.com/#hanatools
Launch Eclipse and click on the Workbench icon on the top right of the screen. This will open the default perspective, which is usually the Java perspective.
Click on the Open Perspective icon on the top right of the screen and choose SAP HANA Modeler from the list. This will open the SAP HANA Modeler perspective.
In the Project Explorer view, right-click on an existing project or folder or use the context menu or toolbar to create a new project or folder for your SAP HANA objects.
In the Project Explorer view, right-click on an existing project or folder or use the context menu or toolbar to create a new SAP HANA object of your choice, such as an attribute view, an analytic view, a calculation view or a procedure.
In the editor area, double-click on your newly created SAP HANA object or use the context menu or toolbar to open the SAP HANA object editor. Here you can define the structure, logic and settings of your SAP HANA object using graphical or SQL script tools.
In the editor area, save and activate your SAP HANA object along with its contained elements and dependencies.
In the Project Explorer view, right-click on your SAP HANA object or use the context menu or toolbar to perform various actions on your SAP HANA object, such as previewing data, generating documentation, assigning roles or analytic privileges, creating indexes or partitions, and so on.
