and Sevgi Foundation, Turkey) is a multidatabase system based on OMG's (OMG is a registered trademark, and CORBA, ORB, OMG IDL, Object Request Broker are trademarks of OMG) distributed object management architecture. It is implemented on top of a CORBA compliant ORB, namely, DEC's ObjectBroker (ObjectBroker is a registered trademark of DEC Corp.) [DDO96]. In MIND all local databases are encapsulated in generic Database Object. The interface of the generic Database Object is de ned in CORBA IDL and multiple implementations of this interface, one for each component DBMSs, namely, Oracle7 (Oracle7 is a trademark of Oracle Corp.), Sybase (Sybase is a trademark of Sybase Corp.), Adabas D (Adabas D is a trademark of Software AG Corp.) and MOOD [Dog94] are provided. MIND provides its users a common data model and a single global query language based on SQL. The main functionalities of MIND are global query processing, global transaction management and schema integration. The basic component classes in the system are

Theorizing technologically mediated policing in smart cities: an ethnographic approach to sensing infrastructures in security practices

Smart digital infrastructures predicated on myriads of sensors distributed in the environment are often rendered as key to contemporary urban security governance to detect risky or suspicious entities before or during a criminal event takes place. At the same time, they often involve surveillance of urban environments, and thus not only criminals but also large groups of people and entities unrelated to criminal phenomena can end up under close inspection.This chapter makes its contribution on two levels. For one, it offers a theoretical framework to the research and conceptualization of the role of sensing infrastructures in urban security practices. It shows how insights from Philosophy of Technology and Science and Technology Studies can produce a nuanced understanding of the role of digital technologies in security practices, beyond standard conceptualizations of technology. Moreover, the chapter proposes a geological approach to enrich our repertoire of imagining and researching smart urban ecosystems.Secondly, the chapter contributes to a higher level of transparency of these practices by presenting the results of ethnographic research performed in a set of police organizations that employ sensing infrastructures and algorithmic profiling in their practices. The chapter draws empirically on research performed in the Dutch police, both at municipal and national levels with some additional material gathered in a constabulary in England. In these organizations, resource allocation decisions are often predicated on automated number plate recognition technology that processes data from an array of smart cameras distributed in the environment. In these ways together, the chapter highlights a set of normative issues with implications for the effectiveness and legitimacy of urban security (surveillance) practices in smart environments. Security and Global Affair

Multidatabase system implementation on CORBA

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
