Database management systems are important for organizing data in computerized information systems and allowing accurate and reliable data to be used for decision making. Examples of databases include those used by banks, hotels, airlines, and railways to manage transactions like deposits, withdrawals, and reservations. Macros can automate repetitive tasks by recording actions and allowing them to be replayed with a single click, saving time. It is important to consider security when using macros to avoid accidentally deleting data.

1. In computerized information system data are the basic
resource of the organization. So, proper organization and
management for data is required for organization to run
smoothly. Database management system deals the
knowledge of how data stored and managed on a
computerized information system. In any organization, it
requires accurate and reliable data for better decision

efficiently.
The examples include deposit and/or withdrawal from a
bank, hotel, airline or railway reservation, purchase items
from supermarkets in all cases, a database is accessed.

2. The idea of MACROS

Function and Module

10. RUNNING A MACRO
• Here we will discuss how to Execute, Play
Back, etc.
