The open-source database management system InfluxDB manages and visualizes data from time series databases, in which thousands of data sets from Internet of Things (IoT) devices or sensors are captured in a constant stream of time-stamped data. The current version 2.0 runs as a cloud service with its own user interface and is written in the new scripting, and query language, Flux.
With relational database systems, you use tables to store and manage information. This sounds simple but involves quite complex concepts such as normal forms, key relationships, and JOINs. This article will introduce the basics of the relational database model, compare its advantages and disadvantages, and delimit this type of data storage from alternative approaches, like object databases,…
So, you need a database for your project, but you don’t want to use traditional relational databases with MySQL or MariaDB. Redis could be the solution. This database management system offers an in-memory database with a key-value store providing fast access speeds and simple scalability. Can this open source system also support your project?
In-memory databases enable big data to be analyzed and made available in real time. The quick access speeds are made possible by storing the data on the working memory – hence the name in-memory database. Traditional databases, on the other hand, are based on the method of storing data on the hard disk. How do in-memory databases differ from traditional database systems? And what are the go-to…
A wide array of database models exists, each one with its own advantages and disadvantages. Key Value Stores, for example, provide lightning-quick results because they follow such a simple principle. A key is saved to each value. There are no more specifications. These Key Value Databases are used principally in website design.
Databases are usually based on rows of data. Columnar databases turn this system on its side. Instead of saving each entry one after the other, in a columnar database entries are stored category by category. This results in a decisive speed advantage when working with massive quantities of data. But how exactly does a column-oriented DBMS work?
If you want to release a new web project today, you need to find the right host. Hosts have become a popular alternative for large companies, since they enable convenient outsourcing of certain work areas or data, saving company resources. But how do you know which host and which hosting package best meets your needs? And why is the provider’s security concept such a crucial criterion nowadays?
A working database system is pivotal to maintaining any computer-based system. The central body that regulates the respective data pools here is always a Database Management System (DBMS). The software structures and organizes the data available in the database, and also manages writing and reading permissions for the database system.
Almost every application utilizes databases in one form or another. Besides classic relational databases, document-oriented databases have also become well-established in the course of the development of web apps. Instead of working with complex tables, these document stores use semi-structured data in simple documents. But how exactly does this work?
Apache Cassandra is a column-oriented database management system based on NoSQL. It offers options for horizontal scaling so that you can add any number of individual nodes. Cassandra was originally developed for Facebook, but it is now used by many social networks and scientific institutions that manage large amounts of data. In the following article, we’ll introduce you to this system.
