      Introduction

      The book Title Here is aimed at novice as well as advanced database professionals. In this book I have explained all the concepts that are required for developing a real world database system. The concepts have been explained with the help of an imaginary Hospital database system that stores records of patients, doctors, examinations and patients. After reading this book, you should be able to develop real world databases of your own. All the examples in this book have been executed on MS SQL Server 2017; though you can use any database server you want as most of the queries remain same. Finally, I would advise you to practice these queries as you study them. This will help you understand the concepts better. You will make mistakes but you will learn better.

      Introduction to RDBMS and SQL

      What is a Database?

      There are two parts of a computer application: Logic, which is implemented in the form of code functions and data, upon which the functions act to perform some task. When an application is being executed, it stores data in RAM (Random Access Memory). However RAM is volatile media which means as soon as you close the application the data is wiped out of the RAM. A persistent storage media is required to store data.

      Computer’s hard disk is a persistent storage media. One approach is store data on files in the hard disk. In fact file based storage systems were used in the early days of computers. However storing and managing data with files is a cumbersome task. Especially for huge and complex and data, file based systems are not suited. A more sophisticated and refined approach is required to handle such data. This is where Database Management Systems (DBMS) come to play.

      DBMS are persistent storage systems that employ sophisticated techniques to store, manage, access and manipulate data. Different DBMS systems store data in different formats. DBMS that stores data in the form of related tables are called Relational Database Management Systems RDBMS, which is the most widely used DBMS. DBMS are also commonly known as Database Systems. Classic textbooks of database define database systems as follows:

      A collection of information stored in a computer in such a way that it can be easily accessed, managed and manipulated

      Relational Database Management Systems (RDBMS)

      This book is about SQL, which is the language used to interact with RDBMS. Therefore it is imperative to study some basic RDBMS concepts.

      There are five basic components of RDBMS.

      Table

      Columns

      Fields

      Primary Key

      Foreign Key

      Table

      A database table is used to store data in the form of rows and columns. This is similar to real world data tables which consist of rows and columns. Usually a database table corresponds to real world entity. For instance if you are developing a database for a hospital it can have entities such as patient, doctor, treatment, medicine, wards etc. In your database you can use tables to store record for each of these entities. Let’s take a look at a patient’s table.

      Table 1.0: An example of Patient’s Table

      Table 1.0 contains patients’ information such as its Id, Name, Gender, Age, Blood Group and Phone.

      Rows

      Each row in the database table contains record of one instance of the entity. You can see that there are multiple rows in the patient’s table. Here each row contains record of one patient. No two rows can have record of one patient.

      Columns

      A table column store information about particular attribute of the entity. For instance, if you look at the Table 1.0, each column contains values that correspond to a particular patient attribute. The Name column contains names of the patient, similarly the age column stores information about patients’ ages.

      Primary Key

      Primary key is used to uniquely identify records within a table. The column that contain primary key is called primary key column. Each value in the primary key column should be unique. No two or more than two records can have same value for their primary key column. In Table 1.0 the Id column is the primary key column.

      Foreign Key

      Foreign keys are used to create relationship between two tables. Foreign key column contains values from the primary key column of some other table.

      We will discuss relationships in detail in the next chapter. Brief explanation is given in this section. Let’s create another table and call it Patient_Treatment. This table contains information about different treatments that a patient has undergone. A patient can have multiple treatments. However one record in the Patient_Treatment table belongs to one person. This is a one to many relation between Patient and Patient_Treatment table. To implement this relation a foreign key is added to Patient_Treatment table. This foreign key refers to the primary key of the Patient table. Let’s see how the Patient_Treatment should look like:
