True all relational tables satisfy the 1NF requirements requirements.

The requirements of the 1NF are met by all relational tables. A table in 1NF that has a single-attribute primary key is automatically in 2NF since a partial dependency can only exist if the primary key is made up of several attributes.

The requirements of the 1NF are met by all relational tables. If a table is in 1NF and contains no partial dependencies, it is in 2NF. One or more attributes may be functionally reliant on non-key attributes in a table in 2NF, which is known as transitive dependency.

The correct answer is B. linker.

A linker is a program that combines the object program (the output of the compiler) with the programs from libraries to create a single, executable program.

The linker resolves external references (references to functions or variables defined in other object files or libraries) and combines the object files into a single program that can be run on a computer. The linker is usually invoked by the compiler, although it can also be run independently.

Other programs that are commonly used in the software development process include assemblers (which convert assembly language code into machine code), compilers (which translate source code into object code), and decoders (which convert encoded data into a usable form).

The tables and data that the view is built on are deleted when the DROP VIEW command is used. A view that incorporates calculations can have additional rows. The FULL privilege is included in the GRANT command, which shows that a user has full privileges. Any row in any table can have an index built and maintained for it. Column names that differ from those in the base table cannot be assigned when creating a view. A view is a table that has been descended from. Use the DEFINE VIEW command to define a view.
