, Database Application - CORRECT ANSWERS-Software that helps business users
interact with database systems.
Database Administrator - CORRECT ANSWERS-Responsible for securing the
database system against unauthorized users. A database administrator enforces
procedures for user access and database system availability.
Authorization - CORRECT ANSWERS-Many database users should have limited
access to specific tables, columns, or rows of a database. Database systems authorize
individual users to access specific data.
Rules - CORRECT ANSWERS-Database systems ensure data is consistent with
structural and business rules.
Query Processor - CORRECT ANSWERS-Interprets queries, creates a plan to modify
the database or retrieve data, and returns query results to the application. Performs
query optimization to ensure the most efficient instructions are executed on the data.
Storage Manager - CORRECT ANSWERS-Translates the query processor instructions
into low-level file-system commands that modify or retrieve data. Database sizes range
from megabytes to many terabytes, so the storage manager uses indexes to quickly
locate data.
Transaction Manager - CORRECT ANSWERS-Ensures transactions are properly
executed. The transaction manager prevents conflicts between concurrent transactions.
The transaction manager also restores the database to a consistent state in the event of
a transaction or system failure.
Metadata - CORRECT ANSWERS-Data about the database, such as column names

Relational Database - CORRECT ANSWERS-Stores data in tables, columns, and rows,
similar to a spreadsheet.
Relational Database - CORRECT ANSWERS-All _________ ________ systems
support the SQL query language.
Relational Database - CORRECT ANSWERS-Relational systems are ideal for
databases that require an accurate record of every transaction, such as banking, airline
reservation systems, and student records.
MongoDB (NoSQL) - CORRECT ANSWERS-The newer non-relational systems are
called NoSQL, for 'not only SQL', and are optimized for big data.
SQL Statements - CORRECT ANSWERS-INSERT inserts rows into a table.
