Ecommerce system with evaluation of Boolean expression sets

A method for evaluating Boolean expressions to determine a functionality of an ecommerce website, the method comprising:

• receiving a first set of Boolean expressions comprising a first plurality of unique Boolean expressions, each Boolean expression having an associated identifier and payload and comprising a first Boolean expression having an associated first identifier, wherein the payload comprises a value that is returned when a corresponding Boolean expression is satisfied;
• receiving a second set of Boolean expressions, separate from the first set of Boolean expressions, comprising a second plurality of unique Boolean expressions and comprising a second Boolean expression having the associated first identifier, wherein the second Boolean expression is different from the first Boolean expression;
• for a first mode of operation of the ecommerce website, evaluating only the first set of Boolean expressions to dynamically assemble pages and content on the ecommerce website in accordance to the first mode, wherein in the first mode of operation the first Boolean expression is evaluated;
• for a second mode of operation of the ecommerce website, determining one or more overlapping Boolean expressions between the first set and the second set, evaluating any overlapping Boolean expression in the second set of Boolean expressions as a replacement of the corresponding Boolean expression in the first set of Boolean expressions and evaluating the Boolean expressions in the first set that do not have a corresponding overlapping Boolean expression in the second set, to dynamically assemble pages and content on the ecommerce website in accordance to the second mode, wherein in the second mode of operation the second Boolean expression is evaluated instead of the first Boolean expression;
• wherein each Boolean expression has a corresponding identifier and priority, and two or more Boolean expressions overlap when the two or more Boolean expressions each have an identical identifier and the Boolean expressions are different;
• wherein each set of Boolean expressions comprises a corresponding index;
• wherein the evaluating each of the Boolean expressions comprises receiving values for all variables of each Boolean expression and determining whether the Boolean expression is true or false based on the values, wherein at least one of the values is based on a type of products shown on the ecommerce website, and the evaluating of each of the Boolean expressions comprises returning a payload that corresponds to the each Boolean expression when the expression is true to a user of the ecommerce website via an application program interface (API).

An electronic commerce system comprising:

• one or more processors;
• a storage device coupled to the processor and storing a product catalog, a first set of Boolean expressions comprising a first plurality of unique Boolean expressions, a second set of Boolean expressions comprising a second plurality of unique Boolean expressions, and a Boolean expression evaluation module that comprises instructions;
• the processors executing the Boolean expression module and receiving a product information comprising input facts that comprise Boolean expression keys and values and generating an ecommerce website using the product catalog comprising:
• receiving thea first set of Boolean expressions comprising the first plurality of unique Boolean expressions, each Boolean expression having an associated identifier and payload and comprising a first Boolean expression having an associated first identifier, wherein the payload comprises a value that is returned when a corresponding Boolean expression is satisfied;
• receiving the second set of Boolean expressions, separate from the first set of Boolean expressions, comprising thea second plurality of unique Boolean expressions and comprising a second Boolean expression having the associated first identifier, wherein the second Boolean expression is different from the first Boolean expression;
• for a first mode of operation of the ecommerce website, evaluating only the first set of Boolean expressions to dynamically assemble pages and content on the ecommerce website in accordance to the first mode, wherein in the first mode of operation the first Boolean expression is evaluated;
• for a second mode of operation of the ecommerce website, determining one or more overlapping Boolean expressions between the first set and the second set, evaluating any overlapping Boolean expression in the second set of Boolean expressions as a replacement of the corresponding Boolean expression in the first set of Boolean expressions and evaluating the Boolean expressions in the first set that do not have a corresponding overlapping Boolean expression in the second set, to dynamically assemble pages and content on the ecommerce website in accordance to the second mode, wherein in the second mode of operation the second Boolean expression is evaluated instead of the first Boolean expression;
• wherein each Boolean expression has a corresponding identifier and priority, and two or more Boolean expressions overlap when the two or more Boolean expressions each have an identical identifier and the Boolean expressions are different;
• wherein each set of Boolean expressions comprises a corresponding index;
• wherein the evaluating each of the Boolean expressions comprises receiving values for all variables of each Boolean expression and determining whether the Boolean expression is true or false based on the values, wherein at least one of the values is based on a type of products shown on the ecommerce website, and the evaluating of each of the Boolean expressions comprises returning a payload that corresponds to the each Boolean expression when the expression is true to a user of the ecommerce website via an application program interface (API).
