IRIS - AN INFORMATION RETRIEVAL SYSTEM FOR BRIDGE INVENTORY MAINTENANCE

The Colorado Department of Highways bridge structure inventory has been automated by using the IRIS information storage and retrieval program. IRIS allows rapid and convenient bridge inventory updates and maintenance, selective retrieval of information for report generation, and on-line queries of the data bank. IRIS maintains its principal data bank as a pseudo-inverted list structure on mass-storage devices. Selection of records for retrieval is made by calculation rather than by file search and comparison, and the selected records are reconstructed rather than retrieved as entities. Each category of information (descriptor) is a candidate for use as a key for retrieval, so maximum flexibility and specificity are possible in describing records for retrieval. The user describes a set of bridge records for retrieval by involving 1, some, or all of the descriptors as retrieval keys in Boolean expressions by using a simple and convenient language. Records that belong to the described set are retrieved. The generality of the IRIS design allows it to be used in many applications other than bridge inventory. IRIS is written in FORTRAN and is operational in both batch and interactive modes on the CDC 6400 at the University of Colorado.
