OSX Launchpad icon Removal

After installing a parallels desktop, OSX has a lot of icons in the launchpad, but a lot of it is not what I want, how can we delete or modify it, here are some methods:

① Direct Operation Appications Folder

Launchpad the location of the application are under/applications and/user/name/applications, modify the deletion by themselves

② Operating Database

Some icons may have been deleted, but the icon is still on the launchpad, this can be a relatively simple way to delete, click on the icon, the icon added a question mark, and then drag directly into the trash. Let's talk about the delete operation from the database.
Launchpad Data Save location under/users/name/library/application Support/dock, the files under my Mac are as follows
69cdddad-01d7-40c7-83a4-1e88292d5765.db Desktoppicture.db, this is the name of the long db file, this is a SQLite database saved database files, You can use the Tools mesasqlite GUI tool or command line to operate. Some of the information in the database is shown below. One of the things that is meaningful to us is a table called apps.
