Event processing using barcode generator for .net control to generate, create data matrix barcode image in .net applications. Barcodes FAQs The second aspect of i visual .net DataMatrix ntegration that we want to highlight is of a more technical nature. It concerns the possibilities for event processing within an EDA concept, as shown in the following figure:.

Event-processing techn ologies have been in day-to-day use in many industries for several years. Examples include algorithmic trading in stock markets and Radio Frequency Identification (RFID) in road charging systems. There are three fundamental types of event processing: Simple Event Processing (SEP) Event Stream Processing (ESP) Complex Event Processing (CEP).

[ 47 ]. Basic Principles Simple Event Processing (SEP). Events occur either in dividually, or in streams. Single events can be regarded as an important change in state in a message source and, in particular, in a business event. Events of this kind typically trigger processes in the systems which receive the message.

This form of event processing corresponds exactly with the specification of the Java Messaging Service (JMS). Therefore, a typical example of SEP is JMS..

Event Stream Processing (ESP). ESP involves processin g streams of incoming messages or events. Typical ESP systems have sensors which channel a large number of events, and use filters and other processing methods to influence the stream of messages or events. Individual events are less important, and instead the focus is on the event stream.

Well-known examples include the systems which track stock market prices: one single fluctuation in prices is generally not particularly significant. A more informative overall trend can only be determined from several events..

Complex Event Processi Visual Studio .NET Data Matrix 2d barcode ng (CEP). The third form of even t processing is Complex Event Processing, which is part of ESP. In CEP there is a strong focus on identifying patterns in a large number of events and their (message) contents, which may be distributed across different data streams. The CEP funnel model is illustrated in the following figure:.

[ 48 ]. 1 . The CEP funnel model i visual .net gs1 datamatrix barcode llustrates the process of compressing (large) volumes of events to produce compressed information. The source of the events includes business events (Viehmann 2008).

One of the classic uses of CEP is in tracing credit card fraud. In the case of two transactions using the same credit card, which were made within a short period of time, in locations a long distance apart, this type of geographical and chronological pattern indicating the possibility of fraud, can easily be applied to the model. Systems of this kind, which correlate thousands of events in order to filter out the few cases of fraud or misbehavior, are more and more frequently in use.

. Grid computing/Extreme Transaction Processing (XTP). Grid computing and XTP barcode data matrix for .NET are the new integration technologies, which are likely to become increasingly popular over the next few years. Grid computing: An infrastructure for the integrated, collaborative use of resources.

Grids can be broken down into Data Grids, In-Memory Data Grids, Domain Entity Grids, and Domain Object Grids on the basis of their primary functionality, and are used in a wide range of applications. XTP: This is a distributed storage architecture, which allows for parallel application access. It is designed for distributed access to large, and very large, volumes of data.

. Grid computing Grid computing is the term us .net framework 2d Data Matrix barcode ed to describe all the methods that combine the computing power of a number of computers in a network, in a way that enables the (parallel) solution of compute-intensive problems (distributed computing), in addition to the simple exchange of data. Every computer in the grid is equal to all the others.

Grids can exceed the capacity and the computing power of today"s super computers at considerably lower cost, and are also highly scalable. The computing power of the grid can be increased by adding computers to the grid network, or combining grids to create meta grids..

Definition of a grid A grid i s an infrastructure enabling the integrated, collaborative use of resources which are owned and managed by different organizations (Foster, Kesselmann 1999).. [ 49 ].
