Abstract: A system for reconciling data in a plurality of databases includes a user interface adapted to provide a graphical representation of at least a subset of the records from each of the plurality of databases and to allow for interactive manipulation of the database records through the graphical representation. The plurality of databases are stored on a portable device, or a personal computer. In some embodiments, at least two of the databases have different record structures. The graphical representation includes a visually distinctive graphical scheme for each of the plurality of databases, as well as a visually distinctive graphical scheme for each unique combination of the plurality of databases. Each record found in a single database is displayed using the single database's corresponding graphical scheme and each record found in more than one database is displayed using the graphical scheme corresponding to the combination of databases.
