I’m currently evaluating which NoSQL we could use in a new project and thought I’d document the considered options are and the relevant criteria here.įirst let’s see what a NoSQL database is at all.

NoSQL doesn’t necessarily stand for “No SQL” but rather for “Not only SQL”. 6, 2021 /PRNewswire-PRWeb/ - ArangoDB, the most scalable open source graph database, today announced a 27.8 million Series B financing round led by Iris. So this means it’s a database which can be worked with without using SQL but it doesn’t mean that none of them actually supports an SQL syntax. But the goal is of course not to get rid of SQL but rather to support use cases which are currently not well supported by classical relational database management system (e.g. So what are the main shortcomings of relational databases: Oracle, Sybase ASE, MS SQL Server, MySQL…). In a relational database, all entities stored in the database must be defined with a schema known in advance. The relationships between entities have to be modeled.

Whenever you need to be able to store new types of data or whenever you need to store additional attributes, you need to update your schema and make sure that existing data are made compatible to the new schema. So the effort to setup comes from the fact that to park a car in there, you need to disassemble the car to be able to store it in the garage. This means that the whole structure of the data stored in the database needs to be known in order to create a schema which is required in order to store data. Next, into the config folder we create a database configuration file called db.js within our project with the following content: module.exports = ".`, doc._key) Ĭonsole.The only way to be able to store different types of data not known in advance is to store them as BLOBs which makes it impossible to use any of the advantages of relational databases later on. We then create the article collection, it's a self-explaining word representing an article as in a blog with title and description as main fields.Īs example, here's the screen to create the article Document collection: Let's switch to be connected to the database we have just created (still from the admin panel) so that we'll manage our database to do things like create collections (represents table in relational DBMS). Here is how the dashboard looks like when we're connected as a database root user:ĪrangoDB's multi-model feature allows to manage many types of database with the same engine, for the sake of this article we will create and use a Document database for a basic CRUD API.įrom the dashboard let's create a database called alibabacloudblog as illustrated in the screenshot bellow (owned by the current user: root):

Note: for the next sections to work properly we need to run our ArangoDB server and get the correct database user's credentials to use within our API, by default there is always a root user with an empty password if not customized before.

#ARANGODB ARANGODB SERIES IRIS INSTALL#

Arangojs: the official ArangoDB Javascript driverįrom our project directory in the command line, let's hit the following command to install both of them while letting them persist in the package.json file: npm install express arangojs -save.

ExpressJS: a NodeJS web framework used to implement REST services.

Independently of your project architecture, there are some required npm packages we'll be using to implement a basic API: The communication with ArangoDB server is possible via a REST interface provided many interfaces Let's assume we've done the required study or research and felt down to the fact we need to use ArangoDB to build our NodeJS App.

Have installed ArangoDB on an Alibaba Cloud ECS server.

Basic understanding of NodeJS understanding.

Let's consider we've that base to better follow the current write-up which will show the use of ArangoDB as database management system into a NodeJS project. We've also experimented the command-line and graphical tools to perform some queries on databases, collections and users.

Previously, we've seen how to install ArangoDB into an Alibaba Cloud Elastic Compute Service (ECS) Ubuntu server. OverviewĪrangoDB is a multi-model NoSQL database management system allowing to build high performance applications using a convenient SQL-like query language or JavaScript extensions. is a privately-held company backed by Bow Capital, Iris. Tech Share is Alibaba Cloud's incentive program to encourage the sharing of technical knowledge and best practices within the cloud community. ArangoDB is the most scalable graph database, with more than 12,000 stargazers on. By Dassi Orleando, Alibaba Cloud Tech Share Author.
