Overview of the RAPIDS System
RAPIDS is a client/server system consisting of an ORACLE back-end database (version 7.0), designed using ORACLE CASE tools, and a suite of front-end applications developed using various software tools (e.g., primarily PowerBuilder and SAS). The RAPIDS system includes the following components:
The RAPIDS Database
The RAPIDS database includes the following components:
A FIRE Upload client/application (this application is under development) that will upload the emission factors contained in FIRE into a reference table used to calculate emissions. The Factor Information Retrieval System or FIRE is an emission factor database repository developed by U.S. EPA. The emission factors contained in FIRE have been incorporated into RAPIDS and used within the system to compute emission estimates for certain source categories.)
Data Import and Data Export
Data Import and Data Export client applications facilitate the import of emissions data and estimates maintained by the states external to RAPIDS into the back-end database, and the export of data from the back-end database into ASCII files (i.e., import file format).
The QUERY application provides the user with access to InfoMaker (the InfoMaker software is not provided with RAPIDS), a powerful, easy-to-use ad-hoc reporting tool that lets users query the RAPIDS database and create custom reports of data. This ad-hoc query and reporting tool supplements the pre-defined reports created by the Reporting client/application.
A QC Checker client/application that perform various statistical checks on the emissions data and estimates contained in the ORACLE back-end database. A sample QC Checker screen shows the various options available to the user for performing these statistical checks. Additional statistical checks are expected to be added to the QC Checker application over time.
A Report Generator consisting of various client/applications that generate summary reports of the emissions data and estimates contained in the ORACLE back-end database. A sample Tier 1, 2, 3 Reporting screen shows the various reporting options available to the user for this particular report.
A Data Converter client/application converts the emissions data and estimates into U.S. EPA's AIRS Facility Subsystem (AFS) transaction records. A sample AIRS Converter screen shows the various options available to the user for creating AFS transaction record from RAPIDS.
An Emission Estimator client/application allows the user to compute emission estimates using a variety of emission estimation techniques [e.g., product of activity data and an approved emission factor, speciation of either particulate matter (PM) or VOC emission estimates or user-defined algorithms] that match pre-established SCC/compound-specific methodologies listed in the Air Toxics Protocol. (The protocol is a comprehensive document that describes the methodologies the participating states will use to compile the regional inventory, including the procedures to resolve differences of opinion). A sample emission estimation screen shows the various options available to the user for estimating emissions.
RAPIDS software was designed with several features:
