Final answer:
The tool that can be used to generate, map, and merge rows from two or more data sources is a database query language or SQL. SQL allows you to retrieve, manipulate, and combine data from multiple tables or databases.
Step-by-step explanation:
The tool that can be used to generate, map, and merge rows from two or more data sources is a database query language or SQL (Structured Query Language). SQL allows you to retrieve, manipulate, and combine data from multiple tables or databases.
For example, you can use an SQL JOIN operation to merge rows from two tables based on a common column. This enables you to create meaningful relationships between different datasets and perform operations like filtering, sorting, and aggregating the data.
To illustrate, consider the following SQL query:
SELECT * FROM table1 JOIN table2 ON table1.id = table2.id;
This query would combine the rows from table1 and table2 based on the matching IDs, generating a result set that includes columns from both tables.
