Most AWS API resources, if they define a field Name (or <resource type>Name), use that field as an identifier for the resource itself, and the corresponding Terraform resource defines a field name.

The AWS API resource DBInstance uses the field DBInstanceIdentifier to identify the resource and the field DBName for the name of the initial database to create in the instance. The Terraform resource type aws_db_instance maps DBInstanceIdentifier to identifier, matching our naming conventions.

aws_db_instance maps the field DBName to name, which strips too much of the field name. In addition, there is a substantial amount of practitioner confusion around this unique usage of name.

In version v4.0 of the Terraform Provider for AWS, the field name should be deprecated and the field db_name should be added.

Since the data source aws_db_instance already uses the db_<field> naming pattern for most fields, we could also bring the remainder of the fields on the resource inline with this naming.
