Abstract: We present a new software solution, based on Java, which allows to deploy and access astronomical catalogs in relational database form, with their associated data products. It is already used to provide the public VVDS data via VO and manage zCosmos data within the Italian COSMOS community; it is also used as the second generation Web interface to the XMM-LSS master catalog. DART (Database Access and Retrieval Tool) supplies a Web interface which allows to query catalogs, filter data by conditions on the columns values (even complex expressions), view the results and export them in private user files; it is also possible to make simple plots or retrieve the related data products. The software supports access to more than one catalog at a time (e.g. for multi-band usage) either in parallel, or as a couple linked by pre-built correlation tables, or even viewing the result of an identification among several catalogs as a single virtual table. DART has been designed as a general tool capable of accessing any collection of astronomical database tables and related products. It is highly (and easily) customizable editing simple configuration files and (for an increased flexibility specially concerning data product access) populating appropriately a few administrative database tables. It supports ConeSearch, SSA and SIA Virtual Observatory protocols. DART will be soon released to the astronomical community from the PANDORA Web site (
