Answer to Question 1

TRUE

Answer to Question 2

Data safeguards protect databases and other organizational data. Two organizational
units are responsible for data safeguardsdata administration and database administration. Data
administration refers to an organization-wide function that is in charge of developing data
policies and enforcing data standards. Database administration refers to a function that pertains
to a particular database. ERP, CRM, and MRP databases each have a database administration
function. Database administration develops procedures and practices to ensure efficient and
orderly multiuser processing of the database, to control changes to the database structure, and to
protect the database. Both data and database administration are involved in establishing data
safeguards. First, data administration should define data policies. Then, data administration and
database administrations work together to specify user data rights and responsibilities. Third,
those rights are enforced by user accounts that are authenticated at least by passwords.
