300 - Archive System Design

A database and query engine will be at the core of the Gaia archive system. This work package is devoted to the selection of technologies, development and implementation of these elements for Gaia. The technology choices and the design of the systems should be carefully based on the real user needs, as explored and defined in WP 200. Furthermore, the designed system should support the advanced tools and activities produced in the rest of work packages. The activity should culminate in a full working implementation of the Gaia archive system. In the process, prototypes will be prepared and tested in cooperation with the end users. A relevant point is that the system should be Virtual Observatory compliant and therefore should include a VO layer and the relevant metadata.
