Comprehensive Data Management System

Main Content

The Comprehensive Data Management System (CDMS) is a complimentary tool to Hazus Mulit-Hazard (Hazus-MH) that provides users with the capability to update and manage statewide datasets, which are currently used to support analysis in Hazus-MH. CDMS will function for a single user or shared desktop application.

Currently, Hazus-MH users are required to undertake a large amount of manual effort to incorporate new data into the statewide datasets according to their pre-defined formats. To reduce this effort, CDMS will streamline and automate raw data processing, the conversion of external data sources into Hazus-MH compliant data, and the transfer of data into and out of the statewide datasets. Processing site-specific level and aggregate information at the census block and tract levels will be supported. All new data brought into the system will be validated.

Once data are imported into the statewide datasets, CDMS will allow users to query, sort, export and print information. A backwards compatibility utility will be in place for upgrading previous versions of Hazus-MH databases. CDMS will replace the Building Information Tool (BIT) and Inventory Collection and Survey Tool (InCAST) that are currently available on the Hazus-MH DVD.

CDMS Modules

CDMS is comprised of four modules: the aggregate, site-specific, backward compatibility, and import modules. The aggregate, site-specific, and backward compatibility modules work together. Raw data can be used to generate aggregated data, and if the raw data has location information, then site specific data can also be generated at the same time. Similarly, aggregated data can be generated when generating site-specific data. The backward compatibility component will apply the data conversion and use the aggregate data and site-specific data components to generate the data in Hazus-MH format. The updated data in a study region can also be applied to the state data geo-databases.

Aggregate Module

The aggregate module allows the user to:

  • Capture demographic data,

  • Update the aggregated data (square footage, building count, building and content exposure, and demographics) and Occupancy to Building Type Mapping Schemes to state data geo-databases.

Site-Specific Module

The site-specific module has the following capabilities:

  • Allows the user to update for earthquake, hurricane, and flood parameters for essential facilities

  • Capture bridge and tunnel data

  • Capture various transportation and utility facilities data, and

  • Update Hazus state data geo-databases with the data captured, i.e., ability to update EF.mdb, HPLF.mdb, TRN.mdb and UTIL.mdb. FLSg.mdb, FlVeh.mdb

Site-Specific Features and Census Tracts

For site-specific features, CDMS requires that users provide a latitude/longitude coordinate in one of the following systems: Geographic Projection, Decimal Degree Coordinate System, or North American Datum 1983 (NAD83). A Census Tract ID is not required but recommended. Site-specific features can consist of the following: user-defined, high potential loss, essential, transportation and utility facilities.

If a Census Tract ID is not provided, CDMS will utilize the latitude/longitude coordinate to identify the census tract in which a feature falls and will associate the feature with that Census Tract ID. If a site-specific feature, such as a highway bridge, does not have a Census Tract ID and does not fall within a census tract boundary, CDMS will not accept that feature and will warn the user that the feature requires a Census Tract ID before it can be accepted.

Null Values

When importing data into Hazus via CDMS, required fields for features in Hazus should be populated before the data are uploaded and mapped in CDMS. Fields not populated prior to loading into Hazus via CDMS will result in null values being transferred to Hazus, and Hazus will not be able to count these features in its analysis. Consult the Hazus Data Dictionary for required fields and expected values/formats in the data preparation phase.

CDMS Help and Technical Support

CDMS help is accessible from the pull-down Help Menu. If additional help is required, Technical Support can be contacted via the Hazus Help Desk at https://support.hazus.us. If you do not yet have login credentials for https://support.hazus.us please send an e-mail to helpdesk@support.hazus.us to gain access. The Help Desk is available 24/7. Users can also call the technical hotline at 1-877-336-2627 as an alternative means of support. Please be sure to provide as much relevant information about your issue as possible including your operating environment, data formats, error messages, screenshots of errors, and data samples.

SQL Server 2005 Express Limitations

CDMS operates on a free version of Microsoft® SQL Server 2005 Express relational database software that enables Hazus users to run the CDMS without requiring a software purchase. However, SQL Server 2005 Express has the following limitations:
• Supports only 1 CPU but can be installed on any server,
• 1 GB addressable RAM, and
• 4 GB maximum database size.
