A system and method of efficiently replicating data structures in a distributed system of replicas. Each replica in the distributed system maintains a cursor indicative of the extent to which other replicas in the system are consistent with one another. By examining the information in its cursor, a destination replica requesting replication from a source replica is able to determine the extent to which it has been made consistent with that source replica via indirect paths, thus potentially improving the starting point of replication. The source replica similarly examines its cursor to potentially improve the starting point of replication with respect to the starting point requested by the destination replica. In this manner, redundant information transmitted from a source replica when replicating a destination replica is reduced. The reduction in the amount of transmitted replication data is particularly appreciable when the replication topology of the system is changed such as by adding a new connection between existing replicas or by adding a new replica to the system.

A compressed file produced by a server is used for updating a hypertext markup language (HTML) document cached on a client computer with changes so that it is identical to a changed HTML document stored on a server computer. Typically, when a user requests access to the HTML document on a server computer corresponding to the cached HTML document on the client computer, the cached HTML document is opened and processed by a client agent software module to produce a macro name file and a macro definition file. A checksum or macro name is determined for each construct or list in the cached HTML file. Each macro definition in the macro definition file is a concise content of the construct or list comprising a different portion of the HTML file. The client agent transmits the uniform resource locator (URL) for the site from which the cached HTML document was obtained and appends the macro name file (assuming that the server computer hasn't already generated the macro name file). A server agent at the server site produces a macro compressed file in which the macro name for each section that is unchanged is included, along with the actual contents of those constructs or lists in the HTML file stored on the server computer that have changed. The macro compressed file is transmitted back to the client agent for expansion and to refresh the HTML file that is cached on the client computer. The updated HTML file can then be displayed using the browser on the client computer.

A method and system generate performance data relating to the efficiency of an organization and include the steps of and instructions for describing a plurality of performance variables associated with the organization. The performance variables describe measurable properties of the organization. The invention further maps each of the performance variables to a normalized performance variable mapping that has a neutral value and at least one inflection point of the performance variable within a normalized range of values. Each inflection point describes effects of the normalized performance variable in changing from a positive influence to a negative influence on the organization's efficiency. Then the invention assigns a weighting factor to each of the normalized performance variables to produce a plurality of weighted normalized performance variables. The method and system calculate the efficiency of the organization as a function of the plurality of weighted normalized performance variables. The method and system further include the use and maintenance of instruction tables for identifying interactions among the various performance variables.
