The following example shows the Department-wise Employee count Pivot Table created over the Employee and Department tables using Auto-Join feature. Click here to know more about joining tables. You can drag and drop the required columns from the list into the respective shelves to create the reports. While creating reports, Zoho Analytics will list all the tables that have a lookup relationship in the Column list panel of the Report designer. Zoho Analytics allows you to define a lookup relationship from the import wizard, the table or from the report editor. In Zoho Analytics, tables with lookup relationships can be joined in the following two ways: Lookup columns can be used to join tables where you need to retrieve data from two or more tables in a Workspace. Note: When you manually create a lookup relationship, Zoho Analytics does not check the data columns if the data values adhere to the mentioned cardinality type. In a Many-to-One relationship, the parent table will have unique values and the child table will contain duplicate values. ![]() Each element in the "1" attribute corresponds to one or more elements in the "N" attribute, and each "N" attribute corresponds to one and only one element in the "1" attribute. In a One-to-Many relationship, the parent table will have unique values and the child table will have duplicate values. One-to-Many/Many-to-One Relationship: This is the most common type of relationship.Each element in the "M" attribute (Parent Table) can have multiple matching rows in the "N" attribute (Child Table) and each element in the "N" attribute (Child Table) can have multiple matching rows in the "M" attribute (Parent Table). Many-to-Many Relationship: Many-to-Many Relationship or M-N relationship is where both the columns used to create a relationship have multiple values.This type of relationship is not widespread. One-to-One Relationship: In a one-to-one relationship, the tables that we are trying to connect will have distant values and only one possible relationship can be formed between the two tables.Any two tables can be related using either of the following relationships: When we join two tables in Zoho Analytics, a Parent-Child relationship will be created between the two tables.Ĭardinality refers to the type of lookup relationship that can be created between two tables. In Zoho Analytics, the related columns from multiple tables are joined using a Lookup column relationship using cardinality functions. In a relational database, the related columns from multiple tables are joined using a Foreign key. Once you relate two tables using lookup columns, Zoho Analytics will use this information to enable you create reports by combining columns from these tables, seamlessly without no additional effort. Define familiar models like Star Schema & Snowflake Schema which are optimized for reporting and analysis.Segregate as measures (numeric data columns which you could aggregate) and facts/dimensions (data columns which you use for grouping in reports).Organize your data in a normalized model avoiding duplication of information across tables. ![]() With a feature like Lookup Columns you can, You need to join the tables using a lookup relationship to perform cross-functional analytics. When these tables are imported as separate entities into a workspace, you cannot create reports and dashboards using data from these tables. You would want to import these related tables into Zoho Analytics and create reports and dashboards combining data from these tables. ![]() You might have a database consisting of multiple data tables related to each other.
