Course Description

A database management system (DBMS) is a software package

designed to define, manipulate, retrieve and manage data in a

database. A DBMS generally manipulates the data itself, the data

format, field names, record structure and file structure. It also defines

rules to validate and manipulate this data.

Database management systems are set up on specific data handling

concepts, as the practice of administrating a database evolves. The

earliest databases only handled individual single pieces of specially

formatted data. Today’s more evolved systems can handle different

kinds of less formatted data and tie them together in more ways that

are elaborate.

Course objectives

The student should develop skills and understanding in:

The design methodology for databases and verifying their structural

correctness

Implementing databases and applications software primarily in the

relational model

Using querying languages, primarily SQL, and other database supporting

software

Applying the theory behind various database models and query

languages

Implementing security and integrity policies relating to databases

The basic principles behind data warehousing and preparation for data

analytics

Working in group settings to design and implementing database

projects

Student's obligation

Students who meet classroom obligations contribute to a positive learning environment The media often focuses on a teacher’s role in making sure that students obtain a quality education. While teachers do have a strong impact on the learning process, students also have obligations to their teachers, their classmates and themselves. By fulfilling their fundamental duties, students can contribute to a positive learning experience for everyone in the classroom.

Questions Example Design Q #1) What is DBMS used for? Answer: DBMS, commonly known as Database Management System, is an application system whose main purpose revolves around the data. This is a system that allows its user to store the data, define it, retrieve it and update the information about the data inside the database. Q #2) Why is the use of DBMS recommended? Explain by listing some of its major advantages. Answer: Some of the major advantages of DBMS are as follows:


Controlled Redundancy: DBMS supports a mechanism to control the redundancy of data inside the database by integrating all the data into a single database and as data is stored at only one place, the duplicity of data does not happen. Data Sharing: Sharing of data among multiple users simultaneously can also be done in DBMS as the same database will be shared among all the users and by different application programs. Backup and Recovery Facility: DBMS minimizes the pain of creating the backup of data again and again by providing a feature of ‘backup and recovery’ which automatically creates the data backup and restores the data whenever required. Enforcement of Integrity Constraints: Integrity Constraints are very important to be enforced on the data so that the refined data after putting some constraints are stored in the database and this is followed by DBMS. Independence of data: It simply means that you can change the structure of the data without affecting the structure of any of the application programs. Q #3) What are the different types of languages that are available in the DBMS? Answer: Basically, there are 3 types of languages in the DBMS as mentioned below: DDL: DDL is Data Definition Language which is used to define the database and schema structure by using some set of SQL Queries like CREATE, ALTER, TRUNCATE, DROP and RENAME. DCL: DCL is Data Control Language which is used to control the access of the users inside the database by using some set of SQL Queries like GRANT and REVOKE. DML: DML is Data Manipulation Language which is used to do some manipulations in the database like Insertion, Deletion, etc. by using some set of SQL Queries like SELECT, INSERT, DELETE and UPDATE. What is the purpose of SQL? Answer: SQL stands for Structured Query Language whose main purpose is to interact with the relational databases in the form of inserting and updating/modifying the data in the database. Q #4) Explain the concepts of a Primary key and Foreign Key.


Answer: Primary Key is used to uniquely identify the records in a database table while Foreign Key is mainly used to link two or more tables together, as this is a particular field(s) in one of the database tables which are the primary key of some other table. Example: There are 2 tables – Employee and Department. Both have one common field/column as ‘ID’ where ID is the primary key of the Employee table while this is the foreign key for the Department table. Q#5) What is the main difference between UNION and UNION ALL? Answer: UNION and UNION ALL are used to join the data from 2 or more tables but UNION removes duplicate rows and picks the rows which are distinct after combining the data from the tables whereas UNION ALL does not remove the duplicate rows, it just picks all the data from the tables.

Extra notes:

I have been reviewed this course book, its perfect and feet for this subject

in the level of institute student, so I have no suggestion.
