Using the advantages of integration technique based on Web Services, a CAx/PDM integration framework was constructed to realize the integration of PDM and other application systems. With the framework, the encapsulation of PDM function modules based on .NET Framework was achieved, a dynamic integration method of PDM and CAx systems was provided, the middle format of exchanging data for PDM and other application systems was represented by the XML( Extensible Markup Language) schema to share the information of enterprise application systems. The proposed integration technology can be effectively used to CAx /PDM integration, and meets the manufacturing enterprise's requirement on integrating application system suitably.

Σκοπός της παρούσας διδακτορικής διατριβής ήταν η σχεδίαση-υλοποίηση, προσομοίωση και μοντελοποίηση ασύρματων δικτύων αισθητήρων (ΑΔΑ) που βασίζονται στην αρχιτεκτονική IPv6 over low power wireless personal area networks (6LoWPAN) και υποστηρίζουν υπηρεσίες ιστού (web services) όπως επίσης και η υλοποίηση καινούριων τέτοιων υπηρεσιών καταλληλότερων για εφαρμογή στα προαναφερθέντα ΑΔΑ. Λόγω της έλλειψης που παρατηρείται στην παροχή εργαλείων για την εκπλήρωση του παραπάνω στόχου, αναπτύχθηκε ένα πειραματικό ΑΔΑ και ένα εργαλείο προσομοιωτικών μετρήσεων της επίδρασης των υπηρεσιών ιστού σε 6LoWPAN ΑΔΑ καθώς επίσης και ένα μαθηματικό μοντέλο για την μελέτη του πρωτοκόλλου ελέγχου προσπέλασης στο μέσο μετάδοσης (MAC) αυτών των δικτύων. Το προτεινόμενο MAC πρωτόκολλο για την 6LoWPAN αρχιτεκτονική είναι o χωρίς σχισμή (unslotted) CSMA/CA μηχανισμός του ΙΕΕΕ 802.15.4 προτύπου. Στα πλαίσια της παρούσας διδακτορικής διατριβής υλοποιήθηκε μια καινούρια στοίβα πρωτοκόλλων για υπηρεσίες ιστού η οποία ονομάστηκε Tiny service oriented architecture for wireless sensors (SOAWS). Το Tiny SOAWS προσφέρει μειωμένη κατανάλωση μνήμης, μειωμένο χρόνο εκτέλεσης καθώς επίσης και μειωμένα μεγέθη ανταλλασσόμενων μηνυμάτων σε σχέση με το πρότυπο device profile for web services (DPWS) το οποίο δημιουργήθηκε για την απευθείας ενσωμάτωση των υπηρεσιών ιστού σε συσκευές. Επίσης, το Tiny SOAWS υποστηρίζει την δημιουργία υπηρεσιών ιστού πάνω σε ασύρματους αισθητήρες που έχουν την ίδια σημασιολογία με τις αντίστοιχες υπηρεσίες ιστού του DPWS. Εκτός τούτου, υποστηρίζει μία καινούρια φόρμα μηνυμάτων, η οποία στηρίζεται στην extensible markup language (XML) όπως και η φόρμα μηνυμάτων του DPWS. Τα Tiny SOAWS και DPWS υλοποιήθηκαν πάνω σε πραγματικούς ασύρματους αισθητήρες και συγκρίθηκαν μεταξύ τους χρησιμοποιώντας το αναπτυχθέν πειραματικό ΑΔΑ το οποίο είναι αποτελεί ένα πραγματικό 6LoWPAN ΑΔΑ με τον μέγιστο αριθμό των ασύρματων αισθητήρων του να είναι 12. Με σκοπό την επικύρωση των παραπάνω μετρήσεων, την επέκτασή τους σε μεγαλύτερης κλίμακας ΑΔΑ καθώς επίσης και τη σύγκρισης των 2 προαναφερθέντων στοιβών πρωτοκόλλων με ένα DPWS βασισμένο σε δυαδική κωδικοποίηση (binary-based DPWS), χρησιμοποιήθηκε το αναπτυχθέν εργαλείο προσομοίωσης το οποίο υλοποιήθηκε στον προσομοιωτή network simulator (NS)-2. Επιβεβαιώθηκε η ορθή λειτουργία του πειραματικού ΑΔΑ και του εργαλείου προσομοίωσης συγκρίνοντας τις μετρήσεις του ενός με τις μετρήσεις του άλλου. Το γεγονός αυτό επιτρέπει τη χρήση τους για την αξιολόγηση και σχεδίαση 6LoWPAN ΑΔΑ που υποστηρίζουν υπηρεσίες ιστού. Επιπλέον, η σύγκριση έδειξε ότι το Tiny SOAWS υπερτερεί του DPWS. Ωστόσο, το binary-based DPWS αποτελεί την καλύτερη επιλογή. Παρόλα αυτά, η εφαρμογή του περιορίζεται σε ασύρματους αισθητήρες με συγκεκριμένο λογισμικό καθώς το σύνολο των κανόνων της XML στο οποίο στηρίζονται οι υπηρεσίες ιστού για να προσφέρουν διαλειτουργικότητα στο επίπεδο εφαρμογής δεν χρησιμοποιείται πλέον. Τέλος, οι προβλέψεις του αναπτυχθέντος μαθηματικού μοντέλου για τον unslotted μηχανισμό του MAC υπο-επιπέδου του ΙΕΕΕ 802.15.4 προτύπου συγκρίθηκαν με μετρήσεις από τον NS-2 και βρέθηκε ότι αποκλίνουν ελάχιστα. Ως εκ τούτου, μπορεί να χρησιμοποιηθεί ως εργαλείο αξιολόγησης της σχεδίασης ΑΔΑ τα οποία μπορούν μετέπειτα να υποστηρίξουν την 6LoWPAN αρχιτεκτονική καθώς επίσης και υπηρεσίες ιστού.

A service is an application offered by an organization that can be accessed through a programmable interface. Web services allow computers running on different operating platforms to access and share each other’s databases by using open standards, such as extensible markup language (XML) and simple object access protocol (SOAP). In this chapter, the following Web services mechanisms are discussed: (1) XML encryption, XML signature, and XML key management specification (XKMS); (2) security assertion markup language (SAML); and (3) Web services security (WS-security).

As long as businesses only have one enterprise application or back end application system there is no need to share data with any other system in the company. All data that has to be managed is contained within one back end application system and its database. However, as businesses grow, more back end application systems find their way into their information technology infrastructure managing different specialized business data, mainly introduced due to the growth. These back end application systems are not independent of each other; in general they contain similar or overlapping business data or are part of business processes. Keeping the data in the various application systems consistent with each other requires their integration so that data can be exchanged or synchronized. The technology that supports the integration of various application systems and their databases is called Enterprise Application Integration (EAI) technology. EAI technology is able to connect to back end application systems in order to retrieve and to insert data. Once connected, EAI technology supports the definition of how extracted data is propagated to back end application systems solving the general integration problem.

Web Services (WS) technologies, generally built around the ubiquitous Extensible Markup Language (XML), have provided many opportunities for integrating enterprise applications. However, XML/Simple Object Access Protocol (SOAP), together with Web Services Definition Language (WSDL) and Universal Description Discovery and Integration (UDDI), form a comprehensive suite of WS technologies that have the potential to transcend beyond mere application integration within an organization, and to provide capabilities of integrating processes across multiple organizations. Currently, the WS paradigm is driven through parameters however; the paradigm shift that can result in true collaborative business requires us to consider the business paradigm in terms of policies-processes-standards. This chapter, based on experimental research carried out by the authors, demonstrates how the technologies of WS open up the doors to collaborative Enterprise Architecture Integration (EAI) and Service Oriented Architecture (SOA) resulting in Business Integration (BI). The chapter also provide a quantitative investigation based on organization’s adaptation to mobile and Web Services technologies.
