We use dependency injection to forbid the other crates directly dependencies on the **flowy-sqlite** crate. Each crate defines their database [traits](https://doc.rust-lang.org/book/ch10-02-traits.html) to meet their need.

###Identified Errors with Corrections:

1. Incorrect Phrase / Word Order:

   • Inaccurate:
     "to forbid the other crates directly dependencies on..."
   • Accurate:
     "to prevent other crates from directly depending on..."
     (“forbid” is not used idiomatically here; “directly dependencies” is incorrect.)

2. Subject-Verb Agreement:

   • Inaccurate:
     "Each crate defines their database traits..."
   • Accurate:
     "Each crate defines its database traits..."
     (“Each” is singular, so use “its” not “their.”)

3. Word Choice (Clarity):

   • Inaccurate:
     "...to meet their need."
   • Accurate:
     "...to meet its needs."
     (“Needs” is more natural and matches singular subject “each crate.”)
