Although not strictly marketed as Online Databases, both AwareIM and Bubble are no-code platforms you can use to build database solutions for your business.
AwareIM ( www.awareim.com ) version 8.4 brings some minor improvements and new features.
Bubble ( https://bubble.io ) is definitely an option for building your business solutions and apps. You can build sites and apps which look really professional with complete design and layout flexibility. This is perhaps the main differentiator compared to our Online Databases - but it does mean more work! I have built out a competent CRM solution on the platform whilst others are building web sites/apps. Worth a look.
