  • Patent number: 5388255
    Abstract: An Open Office Directory System stores information in the form of entries in a global database and views in a local database along with a time stamp indicating the date the view was originally written or last modified. Subsets of the selected global entries are stored as views in a local database with the time stamp of the last generation or modification of that view in the global database. The entries in the global database are queried periodically by the local site to compare the time stamps of the local views with the respective entries in the global database. The result of a non-comparison is to update the local view including its time stamp to agree with the global database entry(s).
