This page describes changes made to the LISAT PRISME dashboards.
10/03/2017: The database at the centre of the LISAT system has changed from a MySQL database to an ORACLE database. This has been done to speed up the refreshing of the database when data is uploaded by an ANSP as well as allowing a simpler integration into the PRISME infrastructure. The granularity of the timestamp in ORACLE is much finer (microseconds) than MySQL (one second) and this has resulted in some differences in the processing of the ANSP logs by LISAT. Also the treatment of dual-stack aircraft has been improved. These changes result in minor differences in some counts between the original dashboards and the V2 dashboards.
