1. A system comprising:
a computer; a first data storage as a data source graphically chosen by a user on a window of a graphical user interface (GUI); and a second data storage as a repository graphically chosen by the user on the window of the GUI, wherein the computer is operable to graphically identify a graphical logical data flow on the window of the GUI, the graphical logical data flow being graphically identified by graphically displaying icons chosen by the user on the window of the GUI for the graphical logical data flow, the icons displayed on the window of the GUI including icons for at least the data source, the repository and a data path, the data path being graphically identified between the data source and the repository, wherein the computer is operable to display the graphical logical data flow in a manner that a user can view the displayed graphical logical data flow and can choose a policy, from a plurality of policies as candidates, to be applied to data to be transferred from the data source to the repository of the displayed graphical logical data flow on the window of the GUI by choosing the policy based on the displayed graphical logical data flow on the window of the GUI, wherein a rule compiler in the system is operable to, according to choosing the policy based on the displayed graphical logical data flow on the window of the GUI, translate the chosen policy into a plurality of rules for at least the first and second data storages corresponding to the displayed graphical logical data flow on the window of the GUI including the data source, the repository and the data path, and wherein a rule distributer in the system is operable to distribute the plurality of rules to the at least the first and second data storages according to the translation by the rule compiler, so that the at least the first and second data storages can apply the plurality of rules for the data to be transferred from the data source to the repository of the displayed graphical logical data flow on the window of the GUI. |
