Homogeneous DDBMS
In a homogeneous distributed database all sites have identical software and are aware of each other and agree to cooperate in processing user requests. Each site surrenders part of its autonomy in terms of right to change schema or software. Homogeneous DDBMS appears to user as a single system. The homogeneous system is much easier to design and manage. The following conditions must be satisfied for homogeneous database. The operating system used, at each location must be same or compatible. The data structures used at each location must be same or compatible. The database application (or DBMS) used at each location must be same or compatible.

Famous quotes containing the word homogeneous:
“If we Americans are to survive it will have to be because we choose and elect and defend to be first of all Americans; to present to the world one homogeneous and unbroken front, whether of white Americans or black ones or purple or blue or green.... If we in America have reached that point in our desperate culture when we must murder children, no matter for what reason or what color, we don’t deserve to survive, and probably won’t.”
—William Faulkner (1897–1962)
