You should now have a reasonable idea of how to access DB2 tables to visualize as a map the contents of spatial columns and the results of database queries using spatial predicates. The points, lines, and polygons can be labeled using database column values as well as styled with different colors, symbols, line types, and line widths. You can build custom visualization applications using Java technology and the JViews Maps components. With the JViews Designer, you can create applications with sophisticated symbols that can vary in color, size, and image based on database values. By changing the database connection parameters, these same capabilities are available with DB2 for z/OS, Informix and Netezza databases.
