Hi everyone,

I am new to Datomic and I am trying to get my head around using the client API for my project. Specifically, I am looking for guidance on how to perform basic CRUD operations.

- Create: What’s the best way to add a new entity to the database: ??
- Read: How can I query the database efficiently? Are there any tips for optimizing queries: ??
- Update: What’s the recommended approach for updating existing entities: ??
- Delete: How do I safely remove entities from the database: ??

Any sample code or references would be greatly appreciated. I also read this thread: [https://forum.datomic.com/t/how-to-use-client-api-in-java-application/](https://forum.datomic.com/t/how-to-use-client-api-in-java-application/1912)[aws](https://www.igmguru.com/cloud-computing/aws-developer-certification-training/) but couldn’t get any help.

Thanks in advance…! 😀
