Relationship
Overview
A Relationship in Recurve defines how different Cubes are connected, enabling seamless data integration and enhancing analytical capabilities. Establishing relationships between Cubes ensures consistency, improves query performance, and facilitates the creation of meaningful Views.
Concept of Relationship
A Relationship represents the logical connection between two or more Cubes based on common keys. These relationships allow data from multiple Cubes to be combined, enabling cross-referencing and enriched analysis.
Types of Relationships:
One-to-One (1-1): Each record in one Cube corresponds to exactly one record in another Cube.
One-to-Many (1-n) or Many to One(n-1): A single record in one Cube is associated with multiple records in another Cube.
Why Setup a Relationship?
For View Creation
Relationships allow Views to aggregate and display data from multiple Cubes seamlessly.
Enables pre-joined datasets that improve performance in BI tools.
For Data Consistency and Integrity
Ensures correct data linkage across different datasets.
Reduces redundancy and improves maintainability.
For Enhanced Query Performance
Predefined relationships optimize query execution by reducing the need for complex joins at runtime.
Improves efficiency by leveraging indexed relationships for faster data retrieval.
Define Relationships
To define the relationship between cube, follow these steps:
Click on the Edit Relationship button, the relationship modal will be shown
Click on Add Relationship to start add a new row of the relationship between cube.
Select the Relationship Type, From and To fields in the list and click on Add button.
Once the relationships have been defined, click on the Save button to save all the relationships created.
