What's the difference between coverage.db and cloverMerge.db file?

[Rupesh Rajkumar Bharuka]

Hey,

I have multi-module project and I want to use clover for my integration tests. I have configured clover plugins in my parent module pom.xml file so that all the configuration will be inherited to its child module and using the below command of clover,

mvn clover2:setup install clover2:aggregate clover2:clover -Dmaven.clover.licenseLocation=<path_to_clover_license_file> -P All -Dmaven.test.failure.ignore=true -Dmaven.repo.local=<path_to_maven_repo>

However, when I go to the "target/clover/" path in my parent module I can see that it has generated "cloverMerge.db" file. 

I am surprised about the coverage.db and cloverMerge,db file. is there any difference between both the files?
