Final answer:
Retrieving data from tables in a relational model involves using the SQL language and the SELECT statement.
Step-by-step explanation:
Retrieving data from tables in a relational model involves using the SQL language. One way to retrieve data is through the use of the SELECT statement. This statement allows you to specify which columns you want to retrieve from a table and can also be used to filter the data based on certain conditions.
For example, if you have a table called 'Students' with columns for 'Name', 'Age', and 'Grade', you can retrieve all the names of students who are in the 10th grade by using the following SQL statement:
SELECT Name FROM Students WHERE Grade = '10th'
This statement will return the names of all the students in the 10th grade. You can also retrieve data from multiple tables by using JOIN statements to combine the data from different tables based on specified criteria.
