In Zoho Analytics you can join tables to create reports using one of the following two methods.
When you want to create reports using data spanning across multiple tables, Zoho Analytics provides you with a special feature called Auto-Join. This feature automatically joins tables when creating reports, if the tables are connected using a Lookup column. For this feature to work, you need to specify that two tables are related using the Lookup column. To define a lookup relationship between two tables, it is essential that the tables have at least one column which is common between them. Lets look at this further with an example.
Here's an example to illustrate how to define lookup columns and how Auto-Join combines tables while creating reports, based on lookup relationship
"Store Sales Database" Model:
In the Store Sales Database model given above, the Sales and Sales Person tables have a common column called Sales Person Id. In the 'Sales' table every sale is associated to the Sales Person Id, who did the sale. In the 'Sales Person' table each sales person is identified by a unique id specified in the column Sales Person Id. Similarly Sales and Product Details tables have a common column called Product_ID. In the 'Sales' table each sale is associated with a product identified by the column Product_ID. In the Product table each product is identified by a unique id specified in the column Product_ID.
Given these related columns we can define lookup relationship between Sales and Sales Person table through the column Sales Person Id. Similarly between Sales and Product Details tables a lookup relationship can be established based on the common column Product_ID. Once the lookup column relationship is defined Zoho Analytics will automatically join data from these tables using the Auto-join feature, when you start creating reports based on these tables.
You can define lookup form your existing table or while importing. You can also define a lookup from the report editor. The following section explains how to define lookup between tables.
This section explains how the lookup relationship is defined from tables.
Let's assumed that we have a Store Sales Workspace with the tables as described in the above section. Let's start defining lookup between Sales and Sales Person tables through the common column Sales Person ID.
You can also create a lookup column by following the below steps:
Now, a relationship between Sales and Sales Person tables is established through the lookup column Sales Person ID. Here we call the Sales table as the child table to Sales Persons table, since the Sales table is looking up a column from Sales Person table which is termed as the parent.
Similarly, we can define the lookup relationship between Sales and Product Details table using the Product ID column. Here the lookup column is defined for the Sales table (child table), with Product Details table which is the parent.
Zoho Analytics auto identifies similar columns and provides suggestions for lookup while importing data. The following section explains how this works.
Zoho Analytics allows you to join tables from the report editor when you need to include data from another table. Let's say you want to create a report on Sales by Sales Person. Your Sales table data might just have the Sales Person ID. You can add the Sales Person Name from Sales Person table. The following section explains how this works.
Once tables are related with each other using lookup columns, you can create the reports by selecting any of table with lookup relationship. Zoho Analytics will automatically join the data from these tables and generate the report, when you drag and drop columns from across tables.
Here's how the Sales by each Sales Person chart is created using Auto-Join feature:
The Auto-join feature will automatically join the data from both the Sales and Sales Person table using the Lookup column Product ID and provide the report.
Also, columns from the related tables can be used to filter the report. Continuing the above example, Product Name column from Product Details table can be used to filter the chart data and display Sales made by the Sales Person for the selected Products as shown below.
By default Zoho Analytics will join tables using Left Join. Possible join types are:
Left Join - Report will be computed with all the rows from the child table (left) and only the matching rows from the parent table (right). Matching is done based on lookup columns defined between child & parent tables. This will be the default join type. In this case the Sales table is the child and Sales Person table is the parent.
Right Join - Report will be computed with all the rows from the parent table (right) and only the matching rows from the child table (left). Matching is done based on lookup columns defined between parent & child tables. Here the child will be Sales Person table and parent will be Sales table.
You can choose to change the join type. To do so,
You can link multiple tables using various Lookup columns in your workspace. When creating a report, Zoho Analytics will use the appropriate Lookup columns (Lookup path) created between them and generate the report using the auto join capability.
However, in some cases, this might not suit your specific need. To address this, Zoho Analytics allows you to choose the Lookup path between tables to be used for report creation using the Configure Lookup Path option.
Let's take an example of a Bug tracking Workspace model. Here the Bugs and the Users table are directly joined using two lookup columns i.e., Assignee ID and Reporter ID. The Bugs table also has a lookup to the Projects table using the Projects ID. The Projects and the Users table are joined using the lookup between Owner ID and User ID. This creates an indirect connection between the Bugs and the Users table through the Projects table.
In the above-given model, let's see an example of creating the report Bugs Identified by User. By default, when you plot a report for Bugs identified by each user, Zoho Analytics could use the Assignee ID lookup to Users table, which is not correct as it will provide the Bugs assigned to each user.
In this case, you can change this by selecting Reporter ID as the Lookup column to be used. The following illustration shows how to change the Lookup Column for join.
Now the Bugs identified by Users report, shown below, is generated.
You can also select multiple lookup columns between each pair of tables in a path. This allows you to create reports over data that meet multiple conditions. Let's say you want to create reports on bugs where both the assignee and the reporter are same users. You can do this by selecting both Assignee ID and Reporter ID as lookup columns. The following illustration shows how to select both lookup columns for joining.
Zoho Analytics also allows you to change the lookup path that joins the tables.
Let's say, you need a report on Bugs raised on Projects categorized by owners. Since Bugs and Users are directly joined tables, Zoho Analytics will generate the report as Bugs assigned for Users categorized by Projects. It will ignore the Projects table in-between while generating reports.
To achieve your requirement, you can join the Bugs and the Users tables through the Projects table. The following illustration shows how to change the Lookup Path to join tables.
Now, the Bugs table is linked to the Users table through the Projects table, and retrieves the data for Bugs raised across projects categorized by project owners (User).
Note: You could only configure a single path to connect two tables. You cannot configure different paths for two columns from the same table in the report. However, you can configure different paths for columns from the different tables.
If the generated reports by using Auto-Join feature does not meet your specific needs, you could always create a query table to join the tables and use the same to create reports over it . A query table can be created using a SQL Select Join query to join separate tables using a common column and retrieve data you want from both the tables.
For example, a query to combine the Sales and Sales Person tables and to retrieve Sales made by each Sales Person data can be created as shown below.
The example query above joins the Sales & Sales Person tables. Once you create query table joining the necessary tables, then Zoho Analytics allows you to create any type of reports for analysis and visualization over the same. Click here to learn more about query tables.
