What is a database system?




A database system is a system that stores, organizes, manages, and retrieves data for various purposes. Data is any information that can be represented in a digital form, such as numbers, text, images, audio, video, etc. A database system consists of two main components: a database and a database management system (DBMS).


A database is a collection of data that is organized according to a logical structure or schema. A schema defines the types of data that can be stored in the database, the relationships among them, and the constraints that apply to them. For example, a database for a university might have tables for students, courses, instructors, grades, etc., with attributes such as name, ID, email, title, credit hours, etc., and relationships such as enrollment, teaching, prerequisite, etc.


A DBMS is a software system that provides functions and features for creating, maintaining, manipulating, querying, and accessing databases. A DBMS allows users to define schemas, insert data into tables, update data in tables, delete data from tables, query data from tables using various criteria and operators, join data from multiple tables, aggregate data from tables, perform transactions on tables, ensure data integrity and consistency, control data access and security, optimize data performance and efficiency, backup and restore data, and more.


What are the fundamentals of database systems?




The fundamentals of database systems are the basic concepts and components that underlie any database system. They include data models, database languages, database design, and database management system.


Data models




A data model is a way of representing data in a database system. It defines the types of data that can be stored, the relationships among them, and the operations that can be performed on them. There are different types of data models, such as relational, hierarchical, network, object-oriented, etc. Each type of data model has its own advantages and disadvantages, depending on the nature and complexity of the data and the application requirements.


The most common and widely used data model is the relational data model, which is based on the concept of a table or relation. A table consists of rows or tuples, which represent individual records or entities, and columns or attributes, which represent properties or characteristics of the entities. A table has a primary key, which is a column or a combination of columns that uniquely identifies each row in the table. A table can also have foreign keys, which are columns that refer to the primary keys of other tables, establishing relationships among them.


Database languages




A database language is a way of communicating with a database system. It allows users to define schemas, manipulate data, and query data in a database system. There are different types of database languages, such as SQL, DDL, DML, DCL, etc.


The most common and widely used database language is SQL (Structured Query Language), which is a standard and universal language for relational database systems. SQL consists of several sublanguages, such as DDL (Data Definition Language), DML (Data Manipulation Language), DCL (Data Control Language), etc.


DDL is used to create, alter, and drop tables and other database objects. For example, the following DDL statement creates a table called student with four columns: name, ID, email, and major.


CREATE TABLE student ( name VARCHAR(50), ID INT PRIMARY KEY, email VARCHAR(50), major VARCHAR(50) );


DML is used to insert, update, delete, and query data in tables. For example, the following DML statement inserts a new row into the student table with the values 'Alice', 1234, 'alice@example.com', and 'CS'.


INSERT INTO student (name, ID, email, major) VALUES ('Alice', 1234, 'alice@example.com', 'CS');


DCL is used to grant and revoke permissions and privileges for accessing and modifying data in tables. For example, the following DCL statement grants the SELECT privilege on the student table to a user called Bob.


GRANT SELECT ON student TO Bob;


Database design




Database design is the process of creating a logical and physical structure for a database system. It involves identifying the data requirements, analyzing the data characteristics, choosing a data model, defining schemas, normalizing tables, and implementing indexes and constraints.


One of the most important steps in database design is normalization, which is the process of organizing data in tables to avoid redundancy and inconsistency. Normalization involves applying a series of rules or normal forms to tables, such as 1NF (First Normal Form), 2NF (Second Normal Form), 3NF (Third Normal Form), etc. Each normal form has a specific condition that must be satisfied by a table.


For example, 1NF requires that every column in a table must contain atomic values, meaning that each value cannot be further divided into smaller parts. For example, a column called address that contains both street name and city name violates 1NF, because it can be split into two columns: street and city.


Database management system




A database management system (DBMS) is a software system that provides functions and features for creating, maintaining, manipulating, querying, and accessing databases. A DBMS consists of several components, such as storage manager, query processor, transaction manager, etc.


A storage manager is responsible for storing and retrieving data from disk or memory. It manages the allocation and deallocation of space for data files, the organization and structure of data files, the buffering and caching of data in memory, the compression and encryption of data files, etc.


A query processor is responsible for processing queries from users or applications. It parses and analyzes queries, optimizes query plans, executes query operations, and returns query results. It uses various algorithms and techniques for query optimization, such as cost-based optimization, index-based optimization, join-based optimization, etc.


A transaction manager is responsible for ensuring the ACID properties of transactions. ACID stands for Atomicity, Consistency, Isolation, and Durability. Atomicity means that a transaction must either complete all its operations or none of them. Consistency means that a transaction must preserve the integrity and validity of data. with other concurrent transactions. Durability means that a transaction must persist its effects even in the case of system failures.
