What is PostgreSQL:
PostgreSQL is a free, open-source relational database management system that focuses on SQL conformance and extensibility. With over 30 years of active development, PostgreSQL is
one of the most widely used open-source database tools in the world. PostgreSQL is very stable, it supports different functions of SQL, like foreign keys, subqueries, triggers, as well as different user defined types and functions. This database management system offers features usually found only on commercial systems like Oracle and SQL Server. It can process the most complex types of data, and offers optimal performance in all circumstances. The system also and above all owes its popularity to its open source nature. Thanks to this, this DBMS system is one of the most reliable today.
What you will learn and cover during your lessons:
Introduction to Databases
This module covers the basics of relational databases, including tables, columns, and relationships. You will learn how to create a simple database schema and perform basic CRUD operations.
In this module, you will learn how to use SQL to query a PostgreSQL database. You will learn about basic SQL statements such as SELECT, WHERE, and ORDER BY, and how to use them to retrieve data from a database.
This module covers the different data types available in PostgreSQL, such as integer, text, and date. You will learn how to choose the appropriate data type for a given column in your database schema.
In this module, you will learn how to perform basic administration tasks in PostgreSQL, such as creating users, managing permissions, and creating backups.
This module covers best practices for designing a PostgreSQL database schema, including normalization and denormalization. You will learn how to choose the appropriate data types and create relationships between tables.
In this module, you will learn how to create and use indexes in PostgreSQL to improve query performance. You will learn about different types of indexes, such as B-tree and hash indexes.
This module covers advanced SQL query techniques including joins, subqueries, and aggregate functions. You will learn how to create complex queries to retrieve data from multiple tables.
In this module, you will learn how to create efficient and effective database models using normalization techniques. You will also learn how to design and create relational database schemas.
This module covers how to create and use stored procedures in PostgreSQL. You will learn how to write and execute stored procedures, as well as how to pass parameters to them.
In this module, you will learn techniques for optimizing the performance of PostgreSQL databases. You will learn how to use indexes, analyze queries, and tune the PostgreSQL server for optimal performance.
This module covers best practices for securing PostgreSQL databases. You will learn how to set up user accounts and permissions, encrypt data, and prevent SQL injection attacks.
In this module, you will learn how to back up and recover PostgreSQL databases. You will learn how to create backups, restore data, and recover from failures.
This module covers how to set up and manage database replication in PostgreSQL. You will learn how to create and manage replicas, set up synchronous and asynchronous replication, and monitor replication status.
In this module, you will learn how to use partitioning in PostgreSQL to improve performance and manage large data sets. You will learn how to create partitioned tables, set up partitioning rules, and optimize queries for partitioned data.
This module covers advanced indexing techniques in PostgreSQL, including multi-column indexes, partial indexes, and expression indexes. You will learn how to use these techniques to improve query performance and manage large data sets.
In this module, you will learn how to tune PostgreSQL for high performance and scalability. You will learn how to optimize memory usage, disk access, and query execution, as well as how to use monitoring tools to identify and fix performance issues.
In this module, you will learn advanced administration techniques in PostgreSQL, including user management, security, and auditing. You will also learn how to configure PostgreSQL for high availability and manage upgrades and migrations.
This module covers PostgreSQL replication, including how to set up master-slave and master-master replication, how to monitor replication, and how to perform failover and switchover operations.
In this module, you will learn about PostgreSQL high availability techniques, including how to use load balancing, connection pooling, and failover management tools to ensure maximum uptime for your applications.
This module covers disaster recovery techniques for PostgreSQL, including how to set up hot standby servers, perform point-in-time recovery, and recover from catastrophic failures.
In this module, you will learn about PostgreSQL extensions, including how to install and manage popular extensions such as PostGIS, pgAdmin, and pgBouncer. You will also learn how to create your own extensions.
This module covers advanced performance tuning techniques for PostgreSQL, including how to optimize queries, use indexing effectively, and tune the PostgreSQL server for large-scale applications.
In this module, you will learn about PostgreSQL security, including how to set up SSL encryption, use role-based access control, and prevent SQL injection attacks.
In this module, you will learn advanced techniques for optimizing SQL queries in PostgreSQL. Topics covered include index optimization, query planning, and execution, and performance monitoring.
This module covers advanced data types in PostgreSQL, including arrays, hstore, and JSON. You will learn how to create and manipulate these data types and how to use them in your database applications.
In this module, you will learn how to set up and configure replication in PostgreSQL. Topics covered include replication types, synchronous and asynchronous replication, and replication monitoring.
