The difference between the two and three-tier client/server configuration, are the tiers (layers) that make up the systems. In a two-tier system you have a client and a server, each has the capability of doing the processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012). The software is loaded on the client computer, and access the data server directly. In a three-tier system, there is an additional server/computer between the client and data server; this third component contains the business logic or processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012; Luke, n.d.). A three-tier configuration could be a web-enabled business application.

Conflict – The operation is in content of hierarchy. 3. Structure – The thoughts and expressions are shared accordingly to contribution. 4. Work – The performance of members require distinct roles.
Most of all operational database is stored in a relational database. This optimizes the support of the inquiries transactions. For example, a watch store, each time a watch is sold,, it must be tracked on a daily. The inventory is always updating because it needs to be accounted for.

Microsoft SQL Server supports isolated, durable trans-actions, atomic and consistent,. SQL in-cludes support for database mirroring and clustering. An SQL server cluster is a collec-tion of identically configured servers, which help distribute the workload among multiple servers. SQL server also supports data parti-tioning for distributed databases, in addition to database mirroring which allows the crea-tion of mirrors of database contents, with transaction logs, on another instance of SQL Server, based on certain predefined
