How does tizen manages rpm packages?

BY 27 Sep 2017 General Support
I installed platform image on a target device, image files were generated by MIC, Now what I want to do is replacing one rpm package which is pre-installed on target. How can I replace one rpm on the target? I guess that tizen package manager owns and manages some package database disregarding rpm database, (maybe sqllite?) So maybe, ‘mic’ tools already installed related package/app info package database for that. so I don’t think only removing an rpm package by doing ‘rpm -e xxx.rpm` shouldn’t work well. What is the proper way to install/remove a native application rpm? I found a document – https://wiki.tizen.org/Manually_installing_apps but this is only for ‘wrt-installer’ tool.
