  • Development system with methods for maintaining data integrity of information stored as a data record in a database with a copy of the information displayed on a screen device
    Patent number: 5608898
    Abstract: A development system having methods for maintaining data integrity of information stored as a data record in a database table with information displayed on a screen device is described. An exemplary method for maintaining data integrity, without continuous exclusive locking of a shared data record, includes the following steps. First, the system reads at least one field value from a database table, while the table is available to others (i.e., accessed with share access). This field value is displayed on screen to the user, whereupon the user may enter new information (i.e., new field value). In the event that the user has entered new information, the method performs the step of re-reading the field value from the database table. Accordingly, the method can determine whether the just-entered value differs from that stored in the database.
