Ownership of each table in the database is assigned to only one application, and only an owning application can modify a table owned by the owning application. Each node also schedules running of the applications on the node such that only one application reads from and writes to the database at a time, distributes updates made to the database to every other database, and updates the database in accordance with received distributed updates.
