1. A system for integrating a message-based system with a database-based system, comprising: a computer including a microprocessor; a data parsing component, provided as a shared library to integrate a dataflow of a source system, wherein the data parsing component includes a plurality of parsers, wherein each of the plurality of parsers is configured to parse messages received from a message-based system having a particular message format; and a properties file which indicates properties and data definitions that define how the system is to parse messages from a source format of the source system, to a target format of a target system; wherein the data parsing component operates to read a message from a messaging topic at the source system, present values read from a header of the message to the properties file, select, using the properties file, a parser from the plurality of parsers to parse the message, parse, using the selected parser and the properties file, the message to determine transaction boundaries and operation types, store the parsed message in a persistent trail file, which is subsequently routed via a network to the target system, generate a source definition file from properties in the properties file, which is provided to the target system, and apply the parsed message as database operations at a database at the target system, wherein, if the target system needs to be recovered from an earlier point in time, the persistent trail is deciphered using the source definition file to replay the database operations.
