startups have found a lap in the open source community and haven't seen a satisfying thing. So, with the dream of building a great cloud computing service, they decided to put this thing to a halt first, and set up a database of their own satisfaction. This database is the later famous MongoDB. MongoDB's name needs to be explained. Many people in China feel that
