 DVO uses the following database tables:
 
- * Sky Layout : defines the organization of the object / measurement tables on the sky
- * Photcodes : defines the photometric systems and transformations between them
- * Images : describes the images known the DVO; for a mosaic camera, one chip corresponds to a single image, and an additional meta-image is used to represent the full mosaic (note: these meta-images may soon be moved to a separate table; also note that the mosaic meta-image is only supplied for mosaic images with 'mosaic' astrometry solutions).
- * Average : average properties of the astronomical objects, excluding photometric average information (one row per object)
- * SecFilt : average photometric properties for astronomical objects (one row per 'average' filter per object).
- * Measure : all detections of the astronomical objects
- * Missing : non-detections of known astronomical objects nominally touched by an image (note : this table is not populated by default)

 The standard implementation of DVO uses a stores the database information as a collection FITS tables.  For a subset of the tables (Average, SecFilt, Measure, Missing), the data is partitioned into multiple files representing different regions on the sky.  The partitioning scheme allows for a wide range of scale on which the sky is divided.  At one extreme, the entire sky is represented by a single file.  At the next level, this is split into Declination bands of width 7.5 degrees.  Next, these bands are split into RA ranges.  The next levels subdivide the RA / DEC ranges into smaller and smaller patches.  From the third level on down, the size of the sky regions varies with Galactic latitude to better sample regions of high and low stellar density.
