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.

Fundamentals of Networking IT204-1701A-03 Unit 1 Discussion Board 2 Andrew LeLusche Professor Gregory Roby Colorado Technical University 1/6/2017 Fundamentals of Networking IT204-1701A-03 Unit 1 Discussion Board 2 In order to choose the correct network for your needs, it is important to first understand the differences, advantages, and disadvantages between a peer to peer network and a client/server network. Whether you are a family home, a mom and pop shop, a data center or large corporation- there is a network for your needs. A network is a system of operating machines that allows a user to access an interface suitable for creating and saving documents, access webpages and video/audio content, run administrative programs to serve clients based on whatever business model or service provider you are. First let’s discuss a peer to peer network.

The information or data that needs to be stored could relate to personal employee information that would need to be password protected so only the relevant people can gain access. Only if date if stored in a procedural manner can it be easily retrieved. This can also help if an external body needs to gain access to records for example auditors. Describe the features of different types of systems used for storage and retrieval of information. There are many different ways in which you can store and retrieve information; the main purpose of storing any information is for easy retrieval in the future when it is

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. The time span for an operational must be short to cover but a relational has to have longer time frame to be able to analyze and get the information required.

SQL’s primary query language is Transact-SQL, an imple-mentation of the ANSI/ISO standard Structured Query Language (SQL) used by both Microsoft and Sybase. 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

[C]data storage: 　　　　A hierarchical database is organized into a tree-like structure. The data is stored as records which are connected through links in another database. It contains the collection of fields and records in multiple relationships. It may handle all the unstructured data in a structured
