Answer to Question 1

TRUE

Answer to Question 2

You should look at all the documents that are relevant. Forms are important because they are used to gather the data the database will need. Reports can reveal data that must be included in order to create the summaries that the business requires. Procedures and manuals can help understand how the data is acquired and processed and what rules are applied to it. Even memos and quarterly statements can be useful by providing context for the use and purposes of the data to be stored in the database.
