| Abstract [eng] |
In this work the coordinator model, designed for Internet services systems creation is presented. This model ensures strict system structure, reliability, testability, manageability and also easy modification and creation of different system features. The Internet publishing services system is created, which is designed to prove the appropriateness of the aforementioned coordinator model. The implementation of coordinator service required some effort, but this service greatly relieves the struggle of including new services or modification of existing and can be used when creating new systems. The created Internet publishing services system specification is described further. Afterwards, the system is tested against usability and compliance to coordinator model and is compared to other technologies such as BPEL and chaotic programming. The assumption is posed that coordinator model is best suited for development of small and medium information services systems. The performed research on the subject showed this was truly the case, where BPEL technology was best suited for big systems and not medium and small ones because of complexity and cost issues. The conclusion later is done that information systems are often developed in chaotic and rapidly changing environments so coordinator model is suited for them best because of its ease of changing and establishing of new system components. Therefore, the system created is universal product, which can be naturally adapted for many similar systems. The article was written on this work, which was presented at the 12th interuniversity conference of graduate students “Information society and university studies IVUS’07”. |
