GWQ: A DATA MANAGEMENT AND ASSESSMENT TOOL 2-2 Development of the database involved a number of steps as follows: • Design the system. The findings from meetings with GCC and a review of the nature of existing water quality data allowed the identification of the data needs and requirements which provided the basis for the design; • Transfer existing water quality data, from both hard copy and existing digital formats, into a digital format that was compatible with the requirements and specifications of the GWQ system. This stage also assisted in finalising the standards and specifications for the data, and for testing and fine-tuning the design before further development of software to enter, access, manipulate and report on the data; • Develop software in Microsoft Access for the addition of water quality file records to the database, including vital quality checks of the data prior to addition to the database to ensure integrity of the data and consistency with the requirements of the GWQ system. In addition, applications have been developed in Map Info and Microsoft Excel to facilitate interrogation, analysis and reporting on the data. • Handover, installation and training. Protocols were also developed for the specification of data collection and the digital water quality file format (*.gwq files) that is used by the water quality data management system. 2.2 General Philosophy of Data Flow and Database Structure Figure 2.2 illustrates the general process of data flow between GCC, water quality data providers, the GWQ Database, computer storage and outputs. Furthermore, the structure of the underlying database is shown in Figure 2.3. The database is centred around the “Data Items” table. Each entry in the data items table represents a single water quality file saved in secure storage on GCC’s server. The data set is uniquely identified by a “DataSetID” number and the name of the associated file in secure storage reflects that number, the site at which measurements were made, the water quality parameter measured, and the year and month of measurements. This means that a single file can exist for each unique combination of site, parameter, year and month combination, provided that the appropriate water quality data is available. Further information on data naming conventions is provided in the technical reference manual for the GWQ database (WBM, 2003). The sites, parameters, data sources and entry personnel tables are provided as ancillary tables to assist with the integrity checks undertaken on the data and to assist with presentation of results. The system defaults table contains information on the location of secure storage and a password enabling access to the database for administrative purposes. The functional groups table is provided to assist with the grouping of related sites for analysis. D:\R.N0754.002.01.DOC 7/11/03 16:11
