1. A method for managing accesses to data objects by multiple user programs over a network, comprising:

  • generating a page including at least one editable field of data from at least one data object;

    calculating an initial value from the at least one data object, said initial value reflecting the initial state of information in said data object;

    transmitting the page and the initial value to one user program over the network;

    receiving the page and the initial value from the user program, wherein the received page includes modified data in at least one editable field;

    calculating a current value from the at least one data object after receiving the page, said current value reflecting the current state of information in said data object;

    determining whether the initial value transmitted with the received page is different than the current value; and

    if the initial and current values match, updating the data object with the modified data included in the received page.
