We might be unaware of this fact, but we use time series databases all the time. They will become even more relevant as the Internet of Things (IoT) and other revolutionary technologies continue to develop. In this article, we will review what a time series database is, what its purpose, and their impact on our daily lives.
ArangoDB is a high availability and scalable multi-model NoSQL database that natively works with graphs and documents and includes a full-text search. It is a free, open-source software developed and maintained by ArangoDB GmbH. The system supports three different data models with one database core and includes a unified query language called AQL (ArangoDB Query Language). This query language is declarative and allows the combination of different data access patterns in a single query. The software can be implemented on multiple systems, including Windows, macOS, Linux, Kubernetes, Docker, and on our Managed Cloud. It has a strong community support base on GitHub, StackOverflow, Google Groups, and Slack.
In this tutorial, we will examine what Neo4j is, what it is used for, and how it is implemented. We will also install and configure the installation on an Ubuntu 20.04 server. Neo4j is a graphical database used to create data relationships. Other examples of graphical databases include:
In this article, we will be discussing how to connect to MySQL using Python. Python is one of the most productive and widely used programming languages in use today. Its simple and elegant syntax makes it ideal for new programmers, while experienced programmers enjoy the extensive list of available modules and functionalities.
A MySQL view is simply an ordinary database object that can save SQL query writers a lot of time when used correctly. A view is a stored query that a user can reference just like a table. Many times users will find themselves using the same base query over and over to solve multiple problems. Views are a way of quickly saving that query and referencing it later.
Elasticsearch is a distributed, full-text, open-source search engine. It provides multi-tenant capabilities in analyzing aggregate data types from sources like Logstash or Kibana. This application stores and indexes information, which can then be queried for specific data. It returns useful details about a particular program, log analysis, application performance data, or other information.
Elasticsearch is a distributed, open-source, full-text search engine which provides multi-tenant capabilities for analyzing multiple data types. It stores and indexes data shipped from sources like Logstash or Kibana. Elasticsearch can then be queried for specific data to return useful information about a particular application, log analysis, application performance data, or other information.
Chocolatey or Choco as it is sometimes referred to, is a free, open-source package manager for Windows that is very similar to Apt or DNF in the Linux realm. In other words, this is a program used for installing software via the Windows command line. It downloads a program, installs it, then it will check for updates, and installs those updates automatically if needed. Those who use Linux are quite familiar with the package management systems like this.
Using PhpMyAdmin to search for records and information in your database can quickly help you get the information you need without having to run advanced search queries. This tutorial assumes you have already logged in to PhpMyAdmin, and shows how to search by keyword and for a range of records.
Most Linux distributions ship with a command-line based text editor, usually Vi/Vim or Nano. While both are excellent choices, Vim has a steeper learning curve and can be confusing for beginners. Nano, on the other hand, will feel much more familiar to anyone who has used notepad or other simple text editors in a desktop or other graphical user interface. This is not to say that Nano is not as feature rich as Vim; it is simply more accessible.
