1. A method, comprising: receiving an application at a computing device, the application comprising a stack and a database, the stack comprising one or more pages for a user interface to the application; and executing the application using the computing device, wherein executing the application comprises: locating a compiled script for the application based on a global identifier assigned to the compiled script, the compiled script including a scripting-language instruction for the application, wherein the global identifier comprises an application identifier for specifically identifying the application in a plurality of applications and an object identifier for specifically identifying an object of a computational model, and wherein the computational model is either the stack or the database, injecting the compiled script into the application, executing the injected script in the application, wherein the injected script is configured to perform at least one transaction of the computational model, wherein locating the compiled script comprises: determining that a script is to be compiled; requesting that the script be compiled comprises: receiving the script at a script compiler of the computing device, the script comprising at least one scripting-language instruction for the application, wherein the at least one instruction comprises a script extension for specifying use of the computational model, wherein the script extension comprises a key character and an identifier of the computational model; locating, by the script compiler of the computing device, the script extension within the script based on the key character; determining, by the script compiler of the computing device, the identifier for the computational model specified by the script extension; and generating, by the script compiler of the computing device, the compiled script corresponding to the script, wherein the compiled script comprises scripting-language code that replaces the script extension, and wherein the scripting-language code is configured to access the computational model identified by the identifier of the computational model; and receiving the compiled script, wherein the compiled script corresponds to the script.
