com.gnizr.db.dao.Tag

This class provides a representation of a tag. A tag is consists of three parts: the ID of tag, a String representation of the tag, and the number of times the tag is used to label gnizr bookmarks.

The ID of the tag is usually assigned by the database system when the tag is created for the first time.
