- Why do they call it a relational database? Relational database are usually consisted of different tables which are related to other table by foreign key. And Foreign key in one table is the primary key of a record in another table. We can easily make a query base on different criteria on different table by joining the table.
2.What is SQL? SQL stands for Structured Query Language. It is a Domain Specific Language for managing data in RDBMS
There are two predominant views into a relational database. What are they, and how are they different? They are the data and schema views. Data view displays like a spreadsheet. A schema view descripts the column names and the value type of each column.
In a table, what do we call the column that serves as the main identifier for a row of data? We're looking for the general database term, not the column name.
