Databases / Web Tools
This page is a sub-page of the Milwaukee Makerspace Sensor Array project.
The purpose of this page is to discuss the various database and web tools used in the project. Feel free to make suggestions or comments below.
Database
The database used should be something that the MMS hosts or owns. It should be on or available from the internet so that the MMS website can use it as well as member's personal web pages and smart device apps.
Database
What database does the Makerspace have access to? If none, we should use MySQL. Most hosting sites offer MySQL as an option.
Users
The database should have a user that has both read and write options for the database and a user that only has read options. This way, we could share the read user and password with trusted people so they can make applications.
