PostgreSQL 2023 Training

Course Objectives :

• The PostgreSQL Course aims to provide learners with a comprehensive understanding of PostgreSQL, a powerful open-source database management system. The course is designed to equip learners with the necessary skills to install, configure, and use PostgreSQL to create and manage databases, tables, and data. Below are the course objectives based on the Table of Content:
• PostgreSQL Basic: The course will introduce learners to the basic concepts of PostgreSQL, including its features, advantages, and limitations.
• Creating Database and Tables: Learners will learn how to create databases and tables using SQL queries. They will also understand the different data types and constraints that can be used while creating tables.
• Installing and Configuring PostgreSQL: The course will cover how to install and configure PostgreSQL on different platforms such as Windows, Linux, and macOS.
• Inserting Records: Learners will learn how to insert data into tables in PostgreSQL. They will also learn how to use multi-insert statements to insert multiple records at once.
• Executing Queries from Command Line: The course will cover how to execute SQL queries from the command line using psql, a command-line tool for PostgreSQL. Learners will also learn how to create tables using SQL queries.
• Select, Update, Delete and Upsert Statement: The course will cover how to use select, update, delete, and upsert statements in PostgreSQL to manipulate data in tables.
• More on Upsert: Learners will learn more advanced concepts of upsert statement, such as the conflict clause and exclusion constraints.
• Assignment Explanation: The course will provide learners with assignments to reinforce their understanding of the concepts covered in the course.
• Various Select Clauses: Learners will learn various select clauses, such as distinct, where, and limit, that can be used to filter and manipulate data in tables.
• Using Aggregate Function in Select: The course will cover how to use aggregate functions such as sum, count, and avg, in select statements to summarize data.
• More on Aggregate Functions: Learners will learn more advanced concepts of aggregate functions, such as group by, having, and window functions.
• Using More Clauses in Select Statement: The course will cover how to use more clauses such as order by, between, and case in select statements to filter and manipulate data.
• to_char and like Clause: Learners will learn how to use the to_char and like clauses to convert data types and match patterns in SQL queries.
• More on Like Clause: The course will cover more advanced concepts of the like clause, such as regular expressions and the ilike operator.
• Using Group By and Having Clause: The course will cover how to use the group by and having clauses to group and filter data in SQL queries.
• In summary, the PostgreSQL Course will equip learners with the necessary skills to install, configure, and use PostgreSQL to create and manage databases, tables, and data. Learners will also learn advanced SQL concepts, such as aggregate functions, group by clauses, and various select clauses, to manipulate data in tables. The course is designed to be practical, with assignments to reinforce the concepts learned. Upon completion of the course, learners will have a strong foundation in PostgreSQL and be able to perform various SQL operations efficiently.

Course Description:

• The PostgreSQL Course is designed to provide a comprehensive understanding of the fundamental concepts of PostgreSQL, a powerful open-source relational database management system. In this course, you will learn how to install, configure, and use PostgreSQL to create and manage databases, tables, and data.
• The course starts with an introduction to PostgreSQL Basic concepts, where you will learn about the history, features, and advantages of PostgreSQL. You will also explore the various types of databases and tables to be created and how to download PostgreSQL.
• In the next section, Installing and Configuring PostgreSQL, you will learn how to install and configure PostgreSQL on different operating systems. This section will also cover how to create a database and tables using SQL queries.
• The course will then delve into creating databases, tables using SQL queries. You will learn how to create tables and insert records in the Human Resource database, as well as execute queries from the command line and create tables using queries.
• In the subsequent section, Creating and Inserting Records in SampleDB, you will learn how to create and insert records in SampleDB. You will also learn about the multi-insert statement, which allows for the insertion of multiple records in a single query.
• The course will then explore the use of select, update, delete, and upsert statements. You will also learn more about the upsert statement, which combines insert and update operations in a single statement.
• The course will then cover various select clause types, including the distinct, where, and order by clauses. You will learn how to use aggregate functions in select, such as count, sum, and avg.
• The course will then explore the use of more clauses in the select statement, such as the limit and offset clauses. You will also learn about the between and like clauses and how to use the to_char function in PostgreSQL.
• In the final section, Using Group By and Having Clause, you will learn how to group data based on specific columns using the group by clause. You will also learn how to filter grouped data using the having clause.
• Throughout the course, you will be provided with exercises and assignments to practice your knowledge and skills. At the end of the course, you will have a strong foundation in PostgreSQL and be able to create and manage databases, tables, and data using PostgreSQL.

Pre-Requisites:

• Basic Knowledge of SQL: PostgreSQL is a relational database management system that uses SQL (Structured Query Language) to interact with the database. Therefore, having a basic understanding of SQL concepts such as tables, queries, and data types can be helpful.
• Familiarity with Command Line: PostgreSQL can be interacted with through command-line tools, such as psql. Therefore, it can be helpful to have some familiarity with command-line interfaces.
• Basic Programming Concepts: While not required, having a basic understanding of programming concepts can be helpful when working with databases. Knowledge of variables, functions, and control structures can help when working with complex SQL queries.

Target Customers:

• Software Developers: Developers who need to work with databases and data management systems can benefit from learning PostgreSQL. PostgreSQL is a powerful open-source database management system that can be used to store and manage data for various applications.
• Database Administrators: Database administrators responsible for managing and maintaining databases can benefit from learning PostgreSQL. PostgreSQL provides advanced features for data management, such as data integrity, security, and backup and recovery.
• Data Analysts: Data analysts who need to work with data to extract insights can benefit from learning PostgreSQL. PostgreSQL provides advanced SQL features, such as aggregate functions and group by clauses, which can help analysts query and manipulate data more efficiently.

What will you learn from this course:

• How to install, configure, and use PostgreSQL to create and manage databases, tables, and data. You will gain a strong foundation in PostgreSQL and be able to perform various SQL operations, such as select, insert, update, and delete.
• How to use advanced SQL features, such as aggregate functions, group by clauses, and various select clauses. You will also learn how to use the between, like, order by, and to_char clauses to filter and manipulate data.
• How to manage database security, backup, and recovery. You will learn how to create and manage users, permissions, and roles, as well as how to perform database backups and restore operations.
