During the construction and commissioning phases of the ATLAS Collaboration, data related to the installation, testing and performance of the equipment are stored in distinctive databases. Each group acquires information and saves them in repositories placed in different servers, using diverse technologies. Both data modeling and terminology may vary among the storage areas. The development of retrieval systems for each data set would require too much effort and high maintenance cost. The goal of the Glance Project is to provide navigation mechanisms among the databases, which is independent of both the technology used to build them and their relationship. The browsing over the data sets results in hypertext tables and links on the Web. The user chooses the database and the system shows its structure. After selecting a partition of the repository, the system automatically creates a retrieval interface that allows the specification of search parameters. The interface can be customized for specific needs and saved in order to be easily accessed later. Glance corresponds to a single system that handles distinctive recovery mechanisms among diverse databases. Therefore, further knowledge about how data is organized and labeled is not required to perform queries. Maintenance costs are also minimized. This paper describes the Glance conception, its development and functionalities. The system usage is illustrated with some examples. Current status and future work are also discussed.
