The most widespread use of multitier architecture is the three-tier architecture (for example, Cisco's Hierarchical internetworking model). N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or ...
ScalaLoci is a language that targets generic distributed systems rather than the Web only, i.e., it is not restricted to a client–server architecture. To this end, ScalaLoci supports peer types to encode the different tiers at the type level. Placement types are used to assign locations to data and computations.
Join-patterns provides a way to write concurrent, parallel and distributed computer programs by message passing.Compared to the use of threads and locks, this is a high level programming model using communication constructs model to abstract the complexity of concurrent environment and to allow scalability.
This API is a part of .NET Framework 3.0. A Windows Forms application is an event-driven application supported by Microsoft's .NET Framework.Unlike a batch program, it spends most of its time simply waiting for the user to do something, such as fill in a text box or click a button.
For example, the design of a multitier architecture is made simple using Java Servlets in the web server and various CORBA servers containing the business logic and wrapping the database accesses. This allows the implementations of the business logic to change, while the interface changes would need to be handled as in any other technology.
For example, if an Account object has a PhoneNumber property, and that property is assigned a phone number with alphabetic characters, the Account object's IsValid property will become false (making it impossible to save to the database) and then a new BrokenRule object will be created and assigned to the Account's Broken Rules collection. The ...
The reactor software design pattern is an event handling strategy that can respond to many potential service requests concurrently.The pattern's key component is an event loop, running in a single thread or process, which demultiplexes incoming requests and dispatches them to the correct request handler.
A business object is an entity within a multi-tiered software application that works in conjunction with the data access and business logic layers to transport data. [ citation needed ] Business objects separate state from behaviour because they are communicated across the tiers in a multi-tiered system, while the real work of the application ...
