Question 7
(a) What is the need for DBMS Softwares?
(b) What are the different functions of the DBMS Softwares?
(a) Database Management Systems (DBMS) are software systems used to store, retrieve, and run queries on data. A DBMS serves as an interface between an end-user and a database, allowing users to create, read, update, and delete data in the database.

(b) Functions of a DBMS

So, what does a DBMS really do? It organizes your files to give you more control over your data.
A DBMS makes it possible for users to create, edit and update data in database files. Once created, the DBMS makes it possible to store and retrieve data from those database files.
More specifically, a DBMS provides the following functions:

• 
  Concurrency: concurrent access (meaning 'at the same time') to the same database by multiple users
  
• 
  Security: security rules to determine access rights of users
  
• 
  Backup and recovery: processes to back-up the data regularly and recover data if a problem occurs
  
• 
  Integrity: database structure and rules improve the integrity of the data
  
• 
  Data descriptions: a data dictionary provides a description of the data
  

Within an organization, the development of the database is typically controlled by database administrators (DBAs) and other specialists. This ensures the database structure is efficient and reliable.
The functions of a DBMS include concurrency, security, backup and recovery, integrity and data descriptions. Database management systems provide a number of key benefits but can be costly and time-consuming to implement.

Question 8
(a)What are ERP Softwares?
(b) Explain how ERP Sofwares help in Corporates.

(a) Enterprise resource planning (ERP) is the integrated management of main business processes, often in real time and mediated by software and technology. ERP is usually referred to as a category of business management software—typically a suite of integrated applications—that an organization can use to collect, store, manage and interpret data from many business activities. ERP systems can be local based or cloud-based. Cloud-based applications have grown in recent years due to information being readily available from any location with Internet access. Traditional on-premise ERP systems are now considered legacy technology.
(b) ERPs allow businesses to quickly access needed information for clients, vendors, and business partners. This contributes to improved customer and employee satisfaction, quicker response rates, and increased accuracy rates. In addition, associated costs often decrease as the company operates more efficiently.
