Apparatus, system and method for persistently storing data in a data synchronization process

A method for exchanging data between a first database management system and a second database management system,

• wherein the second database management system is configured to have a data communication coupling with the first database management system and to receive at least one data item from the first database management system,
• the method comprising the steps of:
• assessing said at least one data item, and
• based on the assessment deciding how to persistently store said at least one data item in the second database management system between a first data storage in a first persistent data storing form and a second data storage in a second persistent data storing form;
• and
• storing the data item according to the decision into said first data storage and optionally storing said data item or a reference to said data item into said second data storage of the second database management system,
• wherein the first persistent data storing form is a database storage structure, and the second persistent data storing form is a sequential order.

A computer-readable storage medium having a computer program stored upon, executable on a computer, for exchanging data between a first database management system and a second database management system,

• wherein the second database management system is configured to have a data communication coupling with the first database management system and to receive at least one data item from the first database management system,
• the computer program comprising:
• means for assessing said at least one data item, and
• based on the assessment means for deciding how to persistently store said at least one data item in the second database management system between two persistent data storing form, and
• means for storing the data according to the decision
• wherein the first persistent data storing form is a database storage structure, and
• the second persistent data storing form that receives the at least one data item or a reference thereto.

A system for exchanging data between database management systems, each embodied on a computer system, comprising:

• a first database management system,
• a second database management system configured to contain a data communication connection with the first database management system and to receive data items from the first database management system,
• the second database management system further comprising:
• a first data storage for persistently storing the data items in a form of a database structure, and
• a second data storage for persistently storing data items in a form of a sequential order,
• wherein the system is further configured to analyze each of the data items based on the analyzing, decode how to persistently store each of the data items between the first and the second data storage in the second database management system and to store the data according to the decision.
