Understanding Tabular Editor 2
Tabular Editor 2 dedicates itself as an advanced UI for managing and developing Azure Analysis Services and Power BI models. It has a great external tool integration with Power BI Desktop that provides expanded capabilities for simplifying models, scripting, and other advanced operations.
Working with Tabular Editor 2 to Optimize Data Models
- Refactoring Measures: Tabular Editor makes shifting and refactoring measures quite simple. With a traditional development environment, the process can be quite labor-intensive. With Tabular Editor 2, you can refactor measures through a straightforward drag and drop approach. Here’s an example: after creating a ‘Sales’ table, you discover that some measures belong to a ‘Revenue’ table. You can easily drag & drop them to the appropriate table using Tabular Editor 2.
- Managing Object-Level Security: Managing object-level security is usually a tough nut to crack, primarily when dealing with multiple data roles and tables. Using the Tabular Editor, the process is uncomplicated, increasing productivity. Tabular Editor provides a powerful and user-friendly interface for configuring such security aspects.
- Complex Model Operations: There’s also the benefit of flexibility that comes with Tabular Editor. You can make multiple changes at once, undo and redo actions, and clone objects without worrying about breaking your data model. This makes your data model more adaptable for modification or expansion whenever business needs change.
For example, if you have a product table, and you want to copy all its measures to a new demographics table, it’s just a matter of copying and pasting them. Tabular Editor handles the complexities in the background, and won’t create any confusion like what could happen when managing these aspects manually.
- Best Practice Analyzer (BPA): Tabular Editor’s BPA is another commendable feature. It comes in handy in identifying measures or attributes that don’t conform to best practices. You can customize these rules according to your environment, making it a robust tool for optimizing your data models.
In conclusion, the use of tools like Tabular Editor 2 can significantly improve the performance, security and overall manageability of your Azure Analysis Services and Power BI projects. Whether you are preparing for the DP-500 exam or seeking to optimize your enterprise’s analytics solution, understanding and implementing a tool like Tabular Editor 2 can be a significant asset.
