PhpMyAdmin is a user-friendly graphical interface to interact with MySQL/MariaDB and is a cornerstone of any web hosting environment. In our phpMyAdmin section, we take on this behemoth subject with tutorials for everyday uses.
ClickHouse is an open-source column-oriented DBMS (or database management system) primarily used for OLAP (or the Online Analytical Processing of queries). It is capable of blazing fast generation of real-time analytical data and reporting utilizing SQL queries. It is fault tolerant, scalable, highly reliable and contains a feature rich tool set.
In a regular database, data is stored in tables, columns, and rows. In a table, the related values are physically stored side by side in one row, which is critical to how it operates. This is how most string type databases work.
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.
MySQL is a robust open-source SQL-based, relational database management system that is used in many software programs and web servers. This article aims to show how to connect to use Python to connect to MySQL and perform some basic tasks.
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.
Once in a while, perhaps on a Development server, MySQL will not be set up with a root password. The aforementioned configuration is generally thought of as against best practices, however, if it is what you’re dealing with, then it could also interfere with PhpMyAdmin.
This error relates to logging into phpMyAdmin, an open source tool used for the administration of MySQL.
The scope of information needed in a table can change overtime, and you may find you no longer need a whole column of data. Removing a column from a table can help get rid of unwanted content, like if a project or product is no longer needed, to help free up disk space on a server, to clean up any empty or unused columns, or even just remove data that may have been duplicated. Removing a column is quick and easy to do in PhpMyAdmin.
This guide assumes that you have already logged in to PhpMyAdmin. We will go over how to delete a column within a table.
Starting on the home page of PhpMyAdmin, using the navigation menu on the left, click on the database name that the table we want to modify.
When working on a database, we sometimes find that additional data should be added for each record, but will not fit into any of the existing fields or structures. Adding a new column into an existing database can help with this problem, and it is very easy to accomplish with PhpMyAdmin.
This guide assumes that you have already logged in to PhpMyAdmin as the root user. Next, we will go over how to copy a table, and then review a few of the options PhpMyAdmin provides.
Managing databases and tables from within PhpMyAdmin is usually very straightforward. This guide will demonstrate how to remove columns and tables from a database using PhpMyAdmin.
We must first state that the potential for unintentional data removal can be elevated when working with any database. Before proceeding, it is highly recommended taking a backup before manipulating any data. Also, prior to amending data, we should confirm is not being used in a live environment.
The structure of a field inside a database table can be easily modified! There are a number of reasons why a column would need to be altered. For example, if the existing values needed to be modified to updated data, if a restructuring of tables were needed, or even to help with optimization. PhpMyAdmin makes modifying fields in database tables very straightforward to accomplish.
