Presentation layer The user interface logic is topmost. In a web application, this layer contains the code responsible for drawing pages or screens, collecting user input, and controlling navigation. Business layer The exact form of this layer varies widely between applications. But it s generally agreed that the business layer is responsible for implementing any business rules or system requirements that users would understand as part of the problem domain. In some systems, this layer has its own internal representation of the business domain entities. In others, it reuses the model defined by the persistence layer. We revisit this issue in chapter 3. Persistence layer The persistence layer is a group of classes and components responsible for saving application data to and retrieving it from one or more data stores. This layer defines a mapping between the business domain entities and the database. It may not surprise you to hear that NHibernate would be used primarily in this layer. Database The database exists outside the .NET application. It s the actual, persistent representation of the system state. If a SQL database is used, the database includes the relational schema and possibly stored procedures. Helper/utility classes Every application has a set of infrastructural helper or utility classes that support the other layers: for example, UI widgets, messaging classes, Exception classes, and logging utilities. These infrastructural elements aren t considered to be layers, because they don t obey the rules for interlayer dependency in a layered architecture. how to read image from pdf using java: extract images from pdf using pdfbox - Stack Overflow how to read image from pdf file using java ExtractImages.java - The Apache Software Foundation!

Privately deployed assemblies are a big win for developers, end users, and administrators because they can simply be copied to an application s base directory, and the CLR will load them and execute the code in them In addition, an application can be uninstalled by simply deleting the assemblies in its directory This allows simple backup and restore as well This simple install/move/uninstall scenario is possible because each assembly has metadata indicating which referenced assembly should be loaded; no registry settings are required In addition, the referencing assembly scopes every type This means that an application always binds to the same type it was built and tested with; the CLR can t load a different assembly that just happens to provide a type with the same name This is different from COM, in which types are recorded in the registry, making them available to any application running on the machine . how to print data in pdf in java: Print jTable Data on Printer pdf file on java - YouTube how to read image from pdf file using java Apache PDFBox Extract Images from PDF Document ...
