70 To determine an appropriate integration strategy, including what technologies to employ, airport management needs to have a basic understanding of current system architecture. This chapter provides discussions of the following: • Systems Architecture, including discussions about open architecture, protocols, and legacy systems; • Integration Strategies and Technologies, including discussions and an assessment of the strengths and weaknesses of various strategies; and • Software Contracts, including descriptions of several standard types of contracts in the context of an airport enterprise, along with some provisions the contracts typically contain.

There can be confusion between the terms open architecture and open source. Open source refers to the legal ownership of the programming language source code used to build the software.

The warehouse uses software to scrub the data -- apply preset business rules and analyze the data -- to use the data in preset calculations to provide needed information. Other systems then go to this central location to get the data as input for their calculations, or in the case of a large data warehouse, data is first distributed to departmental data marts, such as a financial data mart or operations data mart.

Integration Technologies This section describes technologies that an airport enterprise can use to implement a chosen systems integration strategy: • Relational Database, • Online Analytical Processing, • Open Database Connectivity and Java Database Connectivity, • Flat Files, • Extensible Markup Language, and • Web Services. Relational Database A relational database is the most common type of database in use today.

Software Contracts Certain provisions occur frequently in software purchase and maintenance contracts. This section describes several standard types of contracts in the context of an airport enterprise, along with some provisions the contracts typically contain.

Enterprise software agreements should detail every aspect of the implementation and installation of the software, and these aspects should be negotiated into the contract. Because of the complexity of the solution, a phased approach using phased agreements might be considered.
