Files

Files

These alternative representations of the data model are being provided in addition to the HTML browser.

EXPRESS

The following list provides links to the EXPRESS files for the Epicentre Logical Data Model and NDTs.

Projected EXPRESS

The following list provides links to the projected EXPRESS file that is EXPRESS V1 compliant. The simple pattern and quantity types were projected as replicated attributes in each entity using a predefined set of EXPRESS Projection Methods. The geometry types were converted to entities.

Rational Rose

All EXPRESS information was imported into a Rational Rose 98 Model File. In addition, non-EXPRESS information was imported such as documentation, verb phrases, where rule types (e.g., same related instance) and the standard value population code (i.e., OPEN, FIXED, LOCAL). Rational Rose 98 was then used to generate the diagrams which have been included in this release. A zipped version of the file (0.7 MB) is included in this release.

Incremental EXPRESS

The change files which were used as input to the POSC Incremental EXPRESS tool are included in a ZIP file. The included README.TXT file specifies the required order of application.

Relational DDL

The following list provides links to ORACLE DDL source codes for POSC's sample relational implementation of the Epicentre data model. All of these files have been included in a zip file.

Reference Data

The tab delimited refLoadLevelOne files plus a load_list file have been included in a unix compressed tar file. On a UNIX system the files can be expanded by running:

  uncompress -c referenceData.tar.Z | tar xvf -

This will create a new subdirectory, referenceData, and put all the files into it.
