Question

To modify an existing table - for example, to add a new column - the developer opens the metadata form for that table and adds a new row of metadata.

a-true
b-false

Answer 1

Modifying an existing table to add a new column is commonly achieved using a DBMS interface or SQL commands, not through adding a row of metadata to the table.

Step-by-step explanation:

To modify an existing table, such as to add a new column, a developer typically needs to use a database management system (DBMS) interface or a query language like SQL (Structured Query Language). It is not common to modify table structures through a metadata form, as table metadata is usually handled directly through the DBMS. Adding a new row of metadata would not change the structure of the table but rather add a record to the table if the table stores metadata.

To add a column, a developer would typically execute an ALTER TABLE statement that defines the new column within the appropriate database table. It is important for the developer to understand the implications of modifying table structures, as it can affect data integrity, relationships with other tables, and overall database performance.
