Database Servers


We have constructed three database servers to hold the imaging and spectroscopic data for the EDR, as shown in Figure 3. The Catalog Archive Server contains the measured parameters from all objects in the imaging survey and the spectroscopic survey. These are loaded in a database server we built using Objectivity, a commercial, object-oriented database server objy. The skyServer contains identical information, but it is loaded in a database server we built using a commercial, relational database server, SQLServer delaney01. The Data Archive Server contains the rest of the data products for the EDR, such as the corrected imaging frames, which are available for direct download, and the calibrated spectra, which are loaded in an Objectivity database.
