· database structures that allow a thorough description of collected environmental data

· databases use the industry-standard Paradox file format providing very fast access to large databases on IBM-compatible personal computers; large tables may also be stored on SQL database servers such as Oracle, MS SQL Server, and MySQL, and WRDB’s administrative functions used to control access

· the user interface was developed using the Paradox Application Language (PAL) which takes full advantage of the Microsoft Windows graphical user interface

· databases can be imported and exported to a wide variety of alternative spreadsheet, database, and text file formats

· all associated databases can be created, edited, and printed using spreadsheet-type on-screen data forms

· data entry and validation are done in batches, thus maintaining strict quality control

· data may be entered manually using user-defined data entry forms or electronically using an intelligent data conversion program developed specifically for this software

· subsets of data can be extracted with an easy-to-use filtering form, or advanced queries can be used to capitalize on the strength of the underlying Paradox engine

· report-quality tables, graphs, and pictures can be generated on-screen for instantaneous review and analysis or printed on any standard device or to a disk file

· data security is enhanced by password-protection of selected program functions

· an on-line help system provides context-sensitive information to the user, supplementing the User’s Manual
