Sequenced modification of multiple entities based on an abstract data representation

A method for performing operations for modifying physical data comprising a plurality of physical entities and having a particular physical data representation in a database, the method comprising:

• providing an abstract model for defining abstract modification specifications logically describing operations to modify the physical data, the abstract model comprising a plurality of logical field definitions, each logical field definition comprising a logical field name and a reference to at least one access method selected from at least two different types of access methods, wherein the at least one access method comprises a simple access method, a filter access method, or a composed access method, wherein the at least one access method is configured to associate the logical field name to the particular physical data representation;
• receiving user input via a user interface, the input including logical values and logically describing a single abstract modification operation to modify the physical data corresponding to the logical values;
• building at least two separate physical modification statements corresponding to the single abstract modification operation, wherein each of the at least two physical modification statements modifies a different physical entity of the physical data;
• ordering the at least two physical modification statements;
• and
• executing modification operations according to the ordered physical modification statements, whereby the physical data is modified.
