3.0 Using the Database Format (.DBF) OptionRefer to Section 8.0, Discussion of Fields in this manual for complete field descriptions and acceptable entries. DATASET FileThe Dataset can be defined as the electronic equivalent of the cover page for the sampling and analytical results that are submitted to the SRP via hard copy. The DATASET file provides basic information about the sampling event, including site description, investigation phase, consultant, submittal date, and other information. There should be only one record in each Dataset file. The Dataset may represent one or more sampling episodes at a site. For example, the sampling and analytical results of four rounds of quarterly monitoring (at the same site) can be submitted as a single dataset. The structure for the Dataset file (DTST.DBF) is defined in Table 3.1. TABLE 3.1 – File Structure for Dataset file to be named by submitter as DTST.DBF
NOTE: Exact Field Names and Widths are needed so that the information can be accurately inserted into the existing SRP database. If the submitted names or field widths are not compatible with the SRP database, the information may not be transferred accurately to the SRP database, and could result in data loss. In such cases, the file would be rejected.
SAMPLE FileThe second file you will create is the SAMPLE file. The Sample file includes the date and location of the sample and other important information as shown in the Sample Record Table (Table 3.2, below). Each Sample Record requires a specific number of fields, a Name for each field, the Field Type (character, date, or numeric) and the Width of each field. The SAMPLE file contains information about each sample collected at a site. The information is roughly equivalent to field notes, and includes: sample number, date, matrix, field identification, location information, etc. There should be one sample record for each sample collected. A unique sample record is created collectively by the following fields: the SRP ID, the Sample Date, and the Sample Number. Therefore, there can be identical Sample Numbers in a dataset as long as those samples were collected on different dates. The structure for the Sample file (HZSAMPLE.DBF) is defined in Table 3.2 . TABLE 3.2 – File Structure for file to be named by submitter as HZSAMPLE.DBF
NOTE: Exact Field Names and Widths are needed so that the information can be accurately inserted into the existing SRP database. If the submitted names or field widths are not compatible with the SRP database, the information may not be transferred accurately to the SRP database, and could result in data loss. In such cases, the file would be rejected. RESULT FileThe third (last) file you will create is the RESULT File. This file includes the sample date, result type, and analytical concentrations of the contaminants detected in the sample and other important information. Each Result Record requires a specific number of fields, a Name for each field, the Field Type (character, date, or numeric) and the Width of each field. The RESULT file contains the result of the analysis of the sample. The Result file includes the Sample Number, Sample Date, Lab ID, the name of the analyte or parameter, the concentration of the result, QA Qualifier, Method Detection Limit, etc. Each compound analyzed for in each sample collected requires a result record. The structure for the Result file (HZRESULT.DBF) is provided in Table 3.3. TABLE 3.3 – File Structure for file to be named by submitter as HZRESULT.DBF
NOTE: Exact Field Names and Widths are needed so that the information can be accurately inserted into the existing SRP database. If the submitted names or field widths are not compatible with the SRP database, the information may not be transferred accurately to the SRP database, and could result in data loss. In such cases, the file would be rejected.
