ARSData Collection Rebuild Schedule

PHASE 1:Data Collection and Reformat

current: data collection utilizes numerous third party and in-house applications to complete data collection via dial-up and TCP/IP from 4+ logger types

future: data collection and reformat applications need to be replaced by ActiveX controls

design: multiple ActiveX controls will be built to replace third party and in-house data collection and reformat applications. New ActiveX controls will be bolted into DataColl (not AirNow).

PHASE 2:Queuing and Site Maintenance

current: data collection is queued in a PowerBuilder applicationusing a static site list on each data collection PC

future: data collection needs to be queued in VB application such that data collection jobscan be picked-up by any data collection PC as processing time becomes available

design: new data collection queuing and site maintenace application will be built and use ActiveX controls for data collection. This will replace DataColl and the data collection components of AirNow.

PHASE 3:Data Reporting

current: data reporting is completed on each data collection PC

future: data reporting needs to be part of a queuing process so that data delivery can be completedby any data collection machine and different report formats can be programmed by users

design: new data reporting application will be built and will be the final piece in replacing the existing AirNow

PHASE 4:Populate Database and Perform Data Validation

current: data processing is currently handled by separate PowerBuilder application

future: data processing needs to be handled by VB data processing application

design: new data processing application will be built to populate IMC and AQDB databases and perform data validation

Note: phase design will occur as appropriate prior to development on a phase by phase basis
