Airport Operational Data Base

Sophisticated ICT projects demand sophisticated database solutions. Data is vital, storage and retrieval needs to be fast and reliable. To provide all this and more, Infologic developed a Central Database solution, either in combination with its high rated information display products (FIDS, PIAES) or as a standalone environment.

The Infologic Airport Operational Database system is a distributed database that is under the
control of a central database management system (DBMS) in which storage devices are not all
attached to a common CPU. It may be stored in multiple computers located in the same physical location, or may be dispersed over a network of interconnected computers.

Collections of data, i.e. in a single or multiple database(s), can be distributed across multiple
physical locations. A distributed database is divided into separate partitions/fragments. Each
partition/fragment of a distributed database may be clustered, mirrored or replicated (i.e. redundantly stored data for fail-overs, RAID like).
For users, the distribution of this data must be fully transparent. Although the system can be spread out over several hosts, it must present itself as one database system. For
administrators, data storage should be done in logical locations and still be easily maintainable.

Advantages of a distributed system include a rather simple organization structure. Data can be stored in designated areas or locations, storing only related data, while other database setups are stored in a separate location. This way, if an error occurs in a specific part of the database, other parts may not be affected by it. It is a rather economic system; it can be created from a series of cheaper and smaller computers, which as a package are less expensive as one large computer. And last but not least, it is modular. It is easy to expand the system; just add a small computer if more power is necessary, or take out one small computer if it fails, or for maintenance purposes.
