What is Database?

A database is an organized collection of data that has been saved to facilitate easy access, management, and updating. Think of it like a digital filing system where you can store names, phone numbers, or any kind of data in an organized way so you can find and use it whenever you need it. Databases are used everywhere, from websites to apps, to help store and manage data efficiently.

Examples of Database Systems

Examples of databases include a school system that stores student information like names and grades, a bank that keeps track of customer accounts and transactions, or an online store that manages product details, prices, and customer orders. These databases help organize and retrieve information quickly and efficiently.

Uses of Database Management System

DBMS is used in various areas, including railway reservation systems, banking, social media sites, and online shopping, among others. It is essential to the effective management and organization of data across different applications, improving user experiences and guaranteeing seamless functioning.

Railway Reservation System

A railway reservation system is an online tool that allows travelers to book train tickets quickly and easily. It lets users check train schedules, select their seats, make payments, and manage their bookings, such as cancellations or changes. This system streamlines the entire ticketing process, making train travel more convenient for everyone.

Banking

Banking involves managing money and financial transactions through various services like saving, withdrawing, and transferring funds. Modern banking systems use technology to securely store customer information, process transactions, and offer online services, making it easy for people to handle their finances anytime and anywhere. This convenience helps customers manage their money effectively and stay informed about their accounts.

Online Shopping

Online shopping allows people to buy products and services over the internet from the comfort of their homes. Shoppers can browse through various items, read reviews, compare prices, and make secure payments easily. This convenient way of shopping saves time and offers a wide range of choices, making it popular among consumers.

Social media sites are online platforms where people can connect, share, and communicate with others. In addition to posting updates, sharing images and videos, and interacting with friends and family through likes, comments, and messages, users can also establish profiles. These sites help people stay connected and share their lives with a larger community.

Credit Card Exchange

Credit card exchanges refer to the process of transferring money or making payments using a credit card. This allows consumers to buy goods and services without needing cash upfront. When a purchase is made, the credit card company pays the seller, and the cardholder agrees to pay back the amount later, often with added interest.

FAQS – Data Base Management System Notes

What are the benefits of DBMS?

The benefits of DBMS include:

Better data management.
Improved data security.
Easy access to information.
Data integrity (keeping data accurate and consistent).
Support for multiple users.
The ability to back up data quickly.

It also helps reduce data redundancy, avoiding having the same data stored in multiple places.

What are the ACID Properties in DBMS?

ACID properties in DBMS ensure reliable transactions. They stand for:

Atomicity: Each transaction is all or nothing; it either completes fully or not at all.
Consistency: Transactions must exit the database adhering to all regulations and restrictions in a legal state.
Isolation: As a result, transactions are executed independently of one another without interfering with one another.
Durability: Once a transaction is committed, it remains in the database even if there is a system failure.

What are Different Languages Present in DBMS?

In DBMS, there are several languages used, including:

Data Definition Language (DDL): Database structures (such as making tables) are defined and managed using the Data Definition Language (DDL).
Data Manipulation Language (DML): Used to change, add, or remove records from databases.
Data Control Language (DCL): Used to manage permissions (e.g., granting or rescinding access to data).
Transaction Control Language (TCL): Database transactions are managed using Transaction Control Language (TCL).

What is the Full Form of DBMS?

The full form of DBMS is Database Management System.

What is a Database View?

A database view is a virtual table showing data from one or more tables but not storing it. It allows users to see specific information without affecting the actual data in the database.
