PostgreSQL is an open source database management system. It is used for a wide variety of development practices such as software and web design, as well as for handling large datasets (big data). With the goal of teaching you the skills to master PostgreSQL, the book begins by giving you a glimpse of the unique features of PostgreSQL and how to utilize them to solve real-world problems. With the aid of practical examples, the book will then show you how to create and manage databases. You will learn how to secure PostgreSQL, perform administration and maintenance tasks, implement high availability features, and provide replication.
Databricks and Microsoft have jointly developed a new cloud service called Microsoft Azure Databricks, which makes Apache Spark analytics fast, easy, and collaborative on the Azure cloud. Not only does this new service allow data scientists and data engineers to be more productive and work collaboratively with their respective teams, but it also gives them the ability to create and execute complex data pipelines without leaving the platform.
PostgreSQL is an enterprise-level database that competes among proprietary database vendors, owing to its remarkable feature set and reliability without the expensive licensing overhead. This book is a comprehensive and pragmatic guide to developing databases in PostgreSQL. Beginning with a refresher of basic SQL skills, you will gradually be exposed to advanced concepts, such as learning how to program in native PostgreSQL procedural languages, implementing triggers, custom functions, and views. You will learn database optimization techniques such as query optimization and indexing while exploring extensive code examples. Lastly, you will explore foreign data wrappers, implementing extensibility, and improving maintainability.
Security researchers have discovered this week a botnet operation that targets PostgreSQL databases to install a cryptocurrency miner. Then you need to know Linux and open-source software. One of the best ways to pick them up is via a Linux Foundation course. Codenamed by researchers as PgMiner, the botnet is just the latest in a long list of recent cybercrime operations that target web-tech for monetary profits. According to researchers at Palo Alto Networks' Unit 42, the botnet operates by performing brute-force attacks against internet-accessible PostgreSQL databases.
