Abstract
The Data Access System (DAS) is a software for storing, retrieving and querying data and meta-data acquired from instrument workstations or other processing steps. The DAS provides a powerful Data Definition Language (DDL) for describing a custom data model through different ddl-types. Each ddl- type can contain a meta-data section, a binary data section, which can describe a binary table or an image, and a set of relations with other ddl-types. Through the DAS API, the user can create new ddl- objects, populate its meta-data, data and then store the resulting object in the DAS system. Futhermore, the user can retrive a set of a ddl-objects, matching a filter specified as a query string, and then update the objects content.
The aim of this document is to: provide a complete guide to installing the DAS system on the CIWSdev machine; provide a comprehensive guide to configuring the DAS system through the configuration files; describe the key concepts of how the DAS handles the ddl-objects persistency; describe the fundamental API functions and methods.
