Advantages and Disadvantages of Wireless Internet Architectures

Advantages The following are the key advantages of wireless Internet (thin client) architecture: Minimal to zero software deployment. This allows applications to be deployed without any additional client-side configuration. Updates to these applications are also straightforward since only the server has to be updated. Extends Internet computing model. Many corporate applications are based on the Internet model. Wireless Internet is a natural extension to these applications. Familiar user interface. Many users are familiar with a browser interface to their applications. Providing a similar interface on mobile devices allows them to be productive immediately;…Read more …

Multiplexing Techniques in Wireless

Multiplexing is a term used to describe how a signal can be divided among multiple users. This spectrum sharing allows wireless operators to maximize the use of their spectrum to accommodate a large number of users over fewer channels. For digital systems, three main multiplexing techniques are being used for wide area networks: frequency division, time division, and code division. A fourth method, called orthogonal frequency division, is the most complex of all of these methods. It is commonly used in high-speed local area networks, but is starting to grow in popularity for…Read more …

Some Important features of Dot Net.

Interoperability support (Interop) Migrating to .NET from existing languages and platforms has been made much easier. Especially if that environment is COM or Java. COM, Interop is built into the framework, and C# will be very familiar for those developing in Java currently. In fact, Microsoft has a migration utility to automatically migrate existing Java source code into C#. Common language runtime (CLR) This is the engine that is shared among all languages supported in .NET, including C#, VB.NET, Managed C++, J#, and others to come. With the help of the CLR, the…Read more …

Advantages and Disadvantages of Data Accessor pattern

Advantages Clean application code— Application code that is replete with data access details is difficult to read and maintain. Application logic tends to become obscured by the many calls necessary to do even simple database calls. When an application uses a well-designed data accessor abstraction that exposes logical database operations, its code can focus more on its own business logic. Incorporation of optimization strategies— Data access code usually is a primary analysis focal point when tuning an application's performance. Data access code is a common bottleneck source and simple optimizations often have significant…Read more …

Transact-SQL Stored Procedure and Advantages

A Transact-SQL stored procedure is a set of T-SQL code that is stored in a SQL Server database and compiled when used. You create this set of code using the CREATE PROCEDURE command. You can use most Transact-SQL commands in a stored procedure; however, some commands (such as CREATE PROCEDURE, CREATE VIEW, SET SHOWPLAN_TEXT, SET SHOWPLAN_ALL, and so forth) must be the first (or only) statement in a command batch, and therefore aren't allowed in stored procedures. Most Transact-SQL commands behave the same in a stored procedure as they do in a command…Read more …
