Help Required with Complex ER Diagrams for Designing a Multi-tenant Database

Hello Everyone :hugs:,

At the moment, I’m engaged in a project that entails creating multi-tenant databases for SaaS applications. My objective is to use dbdiagram to construct an effective and scalable database structure. Since I’m still learning about multi-tenant designs, I’ve run into a few obstacles. I would be very grateful for any advice or suggestions from the community.

Here is a quick synopsis of my project:

Tenants and Users: Tenants each stand in for companies, and companies have groups of users. It is imperative that I guarantee the secure partitioning of data to prevent access to it by users belonging to different companies.

Shared & Isolated Data: Some data should be shared by all tenants, such as system-wide templates and settings. Nonetheless, for items like accounts for users, orders, and reports, every tenant will have a separate, isolated collection of data.

Scalability: As the variety of users and renters increases, the program must be able to grow effectively. Performance bottlenecks worry me, thus I want to make sure the database design allows for horizontal scaling when needed.

These are the particular queries I have:

Schema Designing: What are the most effective methods for creating a multi-tenant database’s schema? :thinking: Should I think about utilising different databases or schema for each tenant, or can I use one database that has a shared schema across all tenants? :thinking:

Data Partitioning: What is the best way to divide up the data so that performance and security are guaranteed? :thinking: Are there specific database features or indexing algorithms that I should take advantage of? :thinking:

Managing Shared Data: How should I manage data that is accessible to all tenants? :thinking: Is there a better way to store this data, or should it be in its own table? :thinking:

Tools and Techniques: What particular plugins, tools, or features of dbdiagram can make managing and designing multi-tenant databases easier? :thinking:

Case Studies: I’d love to learn about your strategy and any lessons you learnt if you have any previous knowledge of multi-tenant database in a comparable setting.

Thank you :pray: in advance.
