Answer to Question 1

TRUE

Answer to Question 2

A database is considered self-describing because it contains a description of its own structure within the database itself. This description is called the metadata, and it is stored in specialized tables in relational databases. The advantage is that the database is self-documenting, and that a knowledgeable user or a database designer can easily access the metadata. All DBMS vendors provide tools to access the metadata within their products.
