  • Deliverable D6.3.1
    Grant Agreement Number: 257528 KHRESMOI www.khresmoi.eu State of the art, concepts and specification for the “Early software architecture” Deliverable number D6.3.1 Dissemination level public Delivery date 10th of May 2011 Status Version 1.1 Emmanuel Jamin, Vassil Montchev, Author(s) Konstantin Pentchev, revised by Allan Hanbury This project is supported by the European Commission under the Information and Communication Technologies (ICT) Theme of the 7th Framework Programme for Research and Technological Development. D6.3.1: State of the art, Concepts, and specification of the Early Prototype Executive summary This document reports on the foundations of the architecture and integration aspects of the Khresmoi project. This includes the technical and functional requirements that imply technical choices and integration decisions for the architecture design. To provide the architecture description and the system specification, an iterative approach has been followed. The structure of the document reflects the main aspects of this approach. At first, two kinds of state of the art are presented. The first one compiles the systems that use similar technologies into four different domains (information retrieval, semantic web systems, multimedia search engines, and platforms for natural language processing). This permits to situate the technical position of the Khresmoi system and provides recommendations in terms of technical requirements. The second state of the art retraces the main technologies for the system integration. Based on this state of the art, the decision is made to adopt the SOA approach, as it offers the best features in terms of flexibility and scalability to be used in the Khresmoi system.

    METHODS & TOOLS Practical knowledge for the software developer, tester and project manager ISSN 1661-402X Winter 2008 (Volume 16 - number 4) www.methodsandtools.com From Finger in the Air Estimating to Finger Pointing Tracking As Giovanni Asproni says it "estimation is a fundamental activity of every project". Or at least it should be. The meaning of "estimation" varies however often for the different participants to software development projects. For the customer, "estimation" means an almost accurate amount of money he will spend and time it will need before he gets what he wants. For the project manager, it is an early commitment to the customer and from the developer to do something for a deadline. For the developer, it is the amount of time that he thinks he could do the stuff, if everything goes right. The experienced developer will often add a 50% cushion to his estimates, knowing that not everything goes right. You can have an additional meaning in the case of outsourcing. For the salesperson, the estimation is the maximum price he can ask, while still having a lot of chances to sign a deal. A lot of young engineers will remind with astonishment hearing in a pre-sales meeting a salesperson answering to the customer that everything he wants is indeed possible... and for a cheap price too ;o) For a developer, estimation is often equaled to fixing deadlines. He could then feel trapped by the original commitment that created expectations for management and customers. Customers have often two fixed expectations: delivery date and functionalities. Therefore, the effort is the only variable left to adjust the project activity.
