Using Parallel B - Trees As Practical (Correct)
....specialized data structure, not available in most existing DBMSs. In this paper we address the problem of indexing MBRs subject to a more common framework, i.e. aiming at allowing traditional existing DBMSs to index MBRs. We assume such common framework to be B trees (see [EN94, Chapter 5] or [O N94, Chapter 7] among other texts for an introduction) We refer to a data record meaning a two dimensional object along with its non spatial attributes. In our previous work [NDK96, Nas96] we have designed an indexing approach, built on top of a plain B tree which allows the indexing of temporal ....

Expressive Power of SQL - Libkin (2001) (2 citations) (Correct)
....world so there surely must be an answer somewhere in the literature. When one thinks of the limitations of SQL, its inability to express reachability queries comes to mind, as it is well documented in the literature (in fact, in many database books written for very di erent audiences, e.g. [1,5,7,26]) Let us consider a simple example: suppose that R(Src,Dest) is a relation with ight information: Src stands for source, and Dest for destination. To nd pairs of cities (A; B) such that it is possible to y from A to B with one stop, one would use a self join as follows. SELECT R1.Src, ....

Pervasive Privacy with Identity Management - Jendricke, Kreutzer, Zugenmaier (2002) (3 citations) (Correct)
....reduction of the display size because of the additional control elements. Maybe it is better to hide the four extrabuttons and to reduce the whole thing to an adapting start menu and a (small) identity status display and configuration button. Atomicity, Consistency, Isolation, and Durability. [15] 13 4.5 Limits and Vulnerabilities Privacy can be divided into the areas of access control and control of published data [19] Our system allows adjustable access control of personal data and services offered. Naturally, it offers no control over the data after publication. For this, a mechanism ....

Mobile Identity Management - Jendricke, Kreutzer, Zugenmaier (2002) (Correct)
....can be done with cryptographical mechanisms as already described in cl. Availability: Using wireless communication, potentially there are more undesired connection aborts than using wired systems. A possible workaround for the identity management may be a transaction concept known from databases [14] to ensure that important actions are withdrawn either correctly or not at all. Accountability: Concerning the need of proving the sending and receiving of messages, cryptographical mechanisms like digital signatures can be used. Notice: This point addresses the attention of the user [15] ....
....of the sender the connection is broken. In the case of a financial exchange, as it is the case in the banking activities, transaction management is crucial. This can be done in the same manner as with chipcards, obeying the ACID 5 criteria. 5Atomicity, Consistency, Isolation, and Durability. [14] 6 When many contexts are sensed simultaneously, the status line of the PDA shows all of them. When too many contexts are sensed, a hint to press the start button ( is introduced in this case. The order of the available applications shown when pressing the start key reflects the ....
