METU INteroperable DBMS (MIND) is a multidatabase system based on OMG's distributed object management architecture. It is implemented on top of a CORBA compliant ORB, namely, DEC's ObjectBroker. In MIND all local databases are encapsulated in a generic database object. The interface of the generic database object is defined in CORBA IDL and multiple implementations of this interface, one for each component DBMSs, namely, Oracle 7, Sybase, Adabas D and MOOD are provided. MIND provides its users a common data model and a single global query language based on SQL. The main components of MIND are a global query manager, a global transaction manager, a schema integrator, interfaces to supported database systems and a graphical user interface. The integration of export schemas is currently performed by using an object definition language (ODL) which is based on OMG's interface definition language. MIND global query optimizer aims at maximizing the parallel execution of the intersite operations of the global subqueries. Through MIND global transaction manager, the serializable execution of the global transactions (both nested and flat) is provided.

Software development for multi-level Petri Net Based Design Inference Nnetwork Coşkun, Çağdaş; Eren, Abülkadir; Department of Mechanical Engineering (2004) This thesis presents the computer implementation of a multi resolutional concurrent, design inference network, whose nodes are refined by PNDN (Petri Net Based Design Inference Network) modules. The extended design network is named as N-PNDN and consists of several embedded PNDN modules which models the information flow on a functional basis to facilitate the design automation at the conceptual design phase of an engineering design. Information flow in N-PNDN occurs between parent and child PNDN modules in ...
METU Interoperable Database system Dogac, Asuman; Halıcı, Uğur; Kilic, Ebru; Ozhan, Gokhan; Ozcan, Fatma; Nural, Sena; Dengi, Cevdet; Mancuhan, Sema; Arpinar, Budak; Koksal, Pinar; Evrendilek, Cem (1996-01-01) A multidatabase system based on OMG's distributed object management architecture and named Middle East Technical University (METU) INteroperable Database management system (MIND) is presented. MIND employs a dynamic query optimizer. After a query is decomposed, the global subsequeries are sent to the involved Local Database Agent (LDA) objects. The optimization process starts after the first partial result from a LDA object becomes available. For optimizing the intersite operations among these partial resul...
Content based packet filtering in linux kernel using deterministic finite automata Bilal, Tahir; Şehitoğlu, Onur Tolga; Department of Computer Engineering (2011) In this thesis, we present a content based packet filtering Architecture in Linux using Deterministic Finite Automata and iptables framework. New generation firewalls and intrusion detection systems not only filter or inspect network packets according to their header fields but also take into account the content of payload. These systems use a set of signatures in the form of regular expressions or plain strings to scan network packets. This scanning phase is a CPU intensive task which may degrade network p...
Service oriented development through aximatic design Kuloğlu, Ebru; Doğru, Ali Hikmet; Toğay, Cengiz; Department of Computer Engineering (2011) This research combines the methodology proposed in Axiomatic Design Theory (ADT) with a service oriented decomposition approach for systematic development of Service Oriented Architecture compliant systems. A previous study had applied ADT to component oriented development where simultaneous specification and decomposition of models related to requirements, design, product domain, and components were supported. Recently, Web services have gained popularity and they became a more desired alternative to compo...
