New method ensures seamless evolution of database applications for efficient data management.
The article discusses how to update a column-oriented database application when the schema changes. The researchers suggest using a conceptual model to keep track of the changes and ensure data consistency. They outline a four-step approach: 1) update the conceptual model, 2) adjust the schema accordingly, 3) migrate data to maintain integrity, and 4) update the client application. This method helps developers manage database evolution effectively.
