摘要：A program object providing an interface between a computer databasemanager and a client application program external to the interface object. The interfaceobject includes associations between columns of the table and associated editing styles,a retrieve method, and an update method. Each editing style specifies a display formatfor data of the associated column. The column/style associations specify modifyingmethods for modifying data of respective columns of the table. The interface object isprogrammed to allow an applications programmer using the interface object to tailor thecolumn/style associations to the database table without access to source code of theinterface object. The retrieve method accepts an invocation message from the clientprogram, and uses the column/style associations to issue commands to the databasemanager to retrieve data from the database into a buffer maintained by and within theinterface object. The modifying methods accept directives to modify the retrieved data inthe buffer and store a transcript of corresponding modification directives. The updatemethod uses the column/style associations and the modification directives of thetranscript to issue commands to the database manager to update the data of thedatabase table in accordance with the modification directives.
