Lesson 13 Airline Application Implementation and Maintenance Starting with fire, the tools that human beings either harnessed or invented set the stage for civilization, transforming the progress of social relations. Social needs inspire invention. Development of computer applications for the airline industry provides a current case study for this theory. The need for accurate seat inventories and passenger name records set the stage for development and implementation of computer related information and communication technology, the cornerstone of today's global society. Social needs inspired invention and computers became a cornerstone supporting progress in the 20th century. On a global scale, computers have become a source and conduit for information and social interaction that has a potential for removing the barriers that separate human beings. Methodology In software engineering and project management, a methodology is a codified set of practices (accompanied by training materials, formal educational programs, worksheets, and diagramming tools) that may be repeatedly processed to produce software. Software engineering methodologies span many disciplines, including project management, analytical procedures, process specification, design, program coding, testing, and quality assurance. The methodologies guiding this field are collations of all of these disciplines. Management must keep pace with rapidly evolving technical foundations in order to implement the methodologies available for resolution of Information Technology (IT) challenges. Consistent technology advances and improvements in conjunction with a shift toward a standardized enterprise Service-Oriented Architecture (SOA) platform reduce acquisition or Total Cost of Ownership (TCO) of evolving technologies. The incentive for SOA adoption is the link it provides for multiple computational resources, promoting their reuse regardless of the operating platform. Service-Oriented Architecture was reviewed in Lecture 5. Enterprise architects believe that SOA can help businesses respond more quickly and cost-effectively to changing market conditions. This style of architecture promotes reuse at the macro (service) level rather than micro (user) level. It can also simplify interconnection to - and usage of - existing IT legacy assets. In some respects, SOA is an architectural evolution rather than a revolution that incorporates many of the best practices of previous software architectures. With respect to communications systems there has been minimal development of solutions that use truly static bindings (or interfaces) that communicate with other equipment in the network. By formally embracing an SOA approach, system designers can to take advantage of well-defined, highly inter-operable interfaces. Sabre Airline Solutions integrated software provides a suit of application that interact and integrate with to each other, maintaining constant communication. Real-time communication and multiple program integration provides for the alignment of resources when and where needed. This means flight and ground crews, materials and

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
