A method is provided for modifying data in a database, wherein multiple users are each authorized to modify the data at the same time. The method comprises the steps of accessing a specified data set contained in the database, wherein the data set comprises multiple data elements, and forming first and second data sets that are initially both identical to the specified data set. At least some of the data elements of the first data set are selectively modified, while the second data set is kept or retained in an unchanged condition. The first and second data sets are then compared with one another in order to identify each of the modified data elements of the first data set, wherein each modified data elements corresponds to a data element of the specified data set in the database. Each modified data element is written to the specified data set contained in the database, wherein each modified data element replaces its corresponding data element. However, other data elements of the specified data set are not replaced by contents of the first data set.
