1. A method, comprising: reading, via a processor, at least one message flow file that stores a message flow; parsing the message flow stored within the at least one message flow file to obtain parsed message flow information; organizing the message flow, based at least in part upon the parsed message flow information, within a memory as a message flow database structure, where in-memory entries within the message flow database structure represent nodes, connections, and properties used by the message flow; and editing the message flow database structure by changing at least one of the in-memory entries in response to receipt of a structured query language (SQL) statement that specifies an SQL command to execute to change the message flow database structure within the memory; where the parsing and organizing of the message flow file into the message flow database structure within the memory allows localized in-memory SQL editing of the message flow without requiring runtime load operations to load the message flow database structure into a database and thereby improves real-time message flow editing technology while additionally reducing resource utilization.
