The operators used for arithmetic operations are called arithmetic operators.

Some distributed transaction processing systems replicate data at two or more sites separated geographically. A common technique for organizing replicated systems is one in which transactions that update a data item must change all replicas. Hence, one possible integrity constraint in a replicated system is that the values of all of the replicas of an item be the same. Explain howtransactions running on such a system might violate

a. Atomicity b. Consistency c. Isolation d. Durability

The advantages of vector-based animation formats are that they are very compact, due to the vector representation of geometries and the idea of reusing previously defined geometries. Further, the representation is resolution independent, so users can view the animation at any resolution. These formats also allow for customized user interactions, which have more flexibility than the VCR-type controls found with conventional video formats. Unfortunately, one big disadvantage of all vector-based formats is that no conventional browser comes equipped to display them. In order to view these files, a user must be willing to download a player.
