A method to produce a history of at least a portion of a database comprising: providing a data store that includes a record indicating a first event associated with first data that describes a subject matter, and indicating a first time interval during which the first data is effective with respect to the subject matter and indicating a second time interval during which the first data is current with respect to the database; and adjusting the data store upon an occurrence of a new event to, update a first record indicating the first event associated with first data and indicating an end time of the first time interval, and add a second new record indicating a second event associated with second data that describes the subject matter, and indicating a start of a new first time interval that is substantially continuous with an end time of the first time interval and during which the second data is effective with respect to the subject matter and indicating a start of a new second time interval during which the second data is current with respect to the database.

A method for use with a database management system to produce a data structure encoded in computer readable memory that indicates a role associated with a transaction comprising: obtaining page context information that includes userid, subjectid, page name and a transaction identifier; providing a plurality of role views that associate userids and subjectids with role names; using the page name from the page context information to access a page definition relation that provides an association between the page name and at least one subject name; using the at least one subject name from the page definition relation to access a access a role view list that lists one or more of the role views; using the userid and the subjectid from the page context and at least one role view name from the role view list to access at least one role view that includes a matching userid and a matching subjectid; and producing a log roles structure that associates a role name from the at least one accessed role view and a transaction identifier from the page context.

A computerized investment plan accounting system manages data for investment plans with multiple participants and multiple investment funds. When a transaction is entered, one side of the transaction (either units or dollars) may be flagged as pended. When the unit value for the fund is determined and stored, the pended side is calculated, stored, dated, and flagged as fixed. Investment fund balances are accumulated by posting the transactions to investment fund accounts. Individual participant fund balances are determined by accumulating transaction data in a multi-dimensional matrix. The participant fund balances are combined for all participants, and the combined totals are compared to the investment fund balances.

A knowledge engineering tool for building expert systems is disclosed. The knowledge engineering tool includes a knowledge base containing "if-then" rules and an inference engine that includes a plurality of object processors. Each object processor has access to a set of variables defining an object. Rules are selected from the knowledge base and routed to the object processors having access to the objects referenced in the rule. In a parallel processing configuration, each object processor executes on a processing unit and rules are passed as messages.
