A database design tool for client/server development that lets users point
and click to design a graphical, entity-relationship (ER) model of the
business rules governing the data in their applications. Features forward-
and reverse-engineering, and gives users a direct connection to their
system catalog, creating a data model straight from their database tables.
Changes to the data model can be forward-engineered to update the current
database, or used to create a new database in more than 20 supported DBMSs.
Tables, indexes, referential integrity (primary key and foreign key),
defaults, domain/column constraints, and thousands of lines of stored
procedure and trigger code, are all generated automatically, providing a
solid foundation for new development. Also available in versions that
support Visual Basic, PowerBuilder, or SQLWindows, synchronizing
application development with the database design. Extended attributes can
be captured and defined from within the ERwin data model itself and passed
through a bidirectional link, providing the client side with a blueprint
consistent with the server. Ready-to-run, data-aware Visual Basic and
SQLWindows Forms and PowerBuilder DataWindows can be generated directly
from the ERwin database design.ÊÎÌÏÀÍÈÈ
