Now, when talking about free databases, most people may first think of MySQL. Indeed, MySQL has been applied in many domestic fields, especially in website setup. However, PostgreSQL is actually the most powerful, rich, and complex free database. Many of its features are the predecessor of many commercial databases such as Oracle and DB2. As a matter of fact, I recently came into contact with PostgreSQL bec

Now talk about the free database, most people think first of all may be MySQL, indeed MySQL has been used in many areas of the country, especially the site erection. But, in fact, the most powerful, most feature-rich and complex free database should be PostgreSQL. Many of its features are the predecessor of today's many business databases, such as Oracle, DB2, and so on. In fact, the author is also recently because of the needs of the project, contact

[Abstract] There are many database systems, free software database PostgreSQL is a very complete feature of the Free software object---Relational database management system (ORDBMS), its many features are the predecessor of today's many commercial databases. When Linux systems are popular, the PostgreSQL database system is also an efficient and stable database system for your needs. In recent more than a y

How to Evaluate machine learning Models, part 4:hyperparameter TuningIn the realm of machine learning, hyperparameter tuning is a "meta" learning task. It happens to is one of my favorite subjects because it can appear like black magic, yet its secrets is not impenetrable. In this post, I'll walk through what's hyperparameter tuning, why it's hard, and what's kind of smart

tuning rules that every Oracle DBA should follow Over the past decade, Oracle has become one of the most professional databases in the world. For IT professionals, it is important to ensure that Oracle's powerful features are used to improve the productivity of their companies. One of the most effective ways to do this is through Oracle tuning. It has a large number of

From accidentally climbing the blog PostgreSQL is a powerful open-source relational database system. after more than 15 years of development, it has won an excellent reputation in terms of reliability, data integrity, and correctness. it runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, sgi irix, Mac OS X, Solaris, Tru64) and Windows. it fully complies with ACID principles and fully supports foreign keys, joins, views, trigg
