In some embodiments, the presentation manager is configured to provide an interface requesting information regarding a proposal from a digital device over a network and receive the information from the digital device. The business object manager is configured to instantiate a business object based on the received information and store the instantiated business object within a data structure residing in a computer readable medium. The business rule manager is configured to generate a business rule associated with the business object, the business rule comprising instructions to perform an operation, the instructions being conditional based on the instantiated business object. The metadata manager is configured to generate metadata associated with the instantiated business object, store the generated metadata in the computer readable medium, perform the operation based on the business rule and the generated metadata, and instruct the presentation manager to provide a second interface indicating a status of the proposal.
