Automated decision platform

A non-transitory, computer-readable medium storing instructions that when executed by a computer system cause the computer system to perform operations comprising:

• receiving, at a computer system, a set of user-defined rules, wherein the user-defined rules are useable by a computer service to automate a decision flow, wherein the decision flow is associated with determining whether to permit completion of an electronic transaction, and wherein determining whether to permit the completion of the electronic transaction includes determining whether to permit the electronic transaction to be processed by the computer system or to present recommendations to a user of the computer system regarding whether to permit the completion of the electronic transaction;
• receiving, at the computer system, a set of user-defined functions useable by the computer service to supplement the user-defined rules;
• generating, with the computer system from the set of user-defined rules and the set of user-defined functions, a graph model, wherein the graph model is generated without compiling the set of user-defined rules and the set of user-defined functions;
• and
• determining, by the computer system from the graph model, an input dependency model that is indicative of a set of inputs for the set of user-defined rules, a logical relationship among which is indicated by the graph model, wherein the input dependency model is useable to an orchestrator to coordinate accesses to one or more data stores in which the set of inputs is stored;
• wherein one or more automated decisions are determinable by applying the set of inputs to the graph model.

A computer-implemented method comprising:

• receiving, at a multi-tenant computer system of an automated decision platform, a set of user-defined rules written as structured text in a language specific to a context of the automated decision platform, wherein the user-defined rules are useable by a computer service to automate a decision flow, wherein the decision flow is associated with determining whether to permit completion of an electronic transaction, and wherein determining whether to permit the completion of the electronic transaction includes determining whether to permit the electronic transaction to be processed by the multi-tenant computer system or to present recommendations to a user of the multi-tenant computer system regarding whether to permit the completion of the electronic transaction;
• and
• performing, by an instance of an automated decision platform running on the multi-tenant computer system, an automated decision flow using the set of user-defined rules, wherein the performing includes:
• generating, with the automated decision platform, a graph model from the set of user-defined rules;
• receiving, with the automated decision platform, a set of inputs referred to in the graph model;
• and
• determining, with the automated decision platform, one or more automated decisions by applying the set of inputs to the graph model.
