This section, called the data dictionary, documents or rather provides information concerning the data in the database. The file name to run this database is called enviro.wb2. Quattro Pro for Windows was utilized to create the database. Collectively, this database consists of eight separate files that were linked together to develop one large file. Each file represents an industry, whether it is a municipal treatment plant or an industrial factory. In turn, each of the files is placed in separate folders that are labeled accordingly and color coded. What follows next is a detailed portrayal of the attributes (A.K.A., column headings, fields), tuples (A.K.A., rows, records), and file names.
