Over the last thirty plus years, in which computer software applications have been vital to business operations, the concept of client/server applications has evolved. In the early 1980’s the term, Client/Server, primarily referenced capabilities of new powerful centralized hardware. The computer world is different today and the concept is better defined as a system where the different logical components are separated from each other. The first of the three basic logical components is the Presentation Logic. The Presentation Logic is what is shown to the end user and handles the inputs and outputs of the underlying application. The second logical component is the Processing Logic. The Processing Logic handles all of the Input and Output processing and contains all of the business rules and logical processing that drives the system. The final logical component is the Storage Logic, which is where the data is stored and retrieved from and often takes the form of a database. These three components can be found in any type of Client/Server database environment.
How these logical components are grouped together forms the basis of a layering approach to a client/server system. The most basic of these is called a One-tier application, where all three logic components are grouped together as part of the client software. In this configuration each client “application has its own copy of the database engine; only the data is shared, not the database logic itself.” (Fastie, 1999) This type of system is easy to develop but has several drawbacks when many users are using it. To overcome these shortcomings, most applications do not use the One-tier environment and instead use a Two-tier or Three-tier environment to separate the di...

...Server application it is important to examine the different types that are available and how the system will be used. While a One-tier environment may be easy to develop, it may lead to complications down the road when a new interface layer is desired. The same is true for two-tier environments, if too much of the application layer is included inside the client application. However, including the wrong application processing hosted on the server could lead to performance problems and require expensive server hardware to handle client requests. It is important to remember that no one client/server environment will be perfect for all applications.

Using server virtualization to concurrently run various operating system environments on one physical server these issues can be resolved, which enables concurrent improvement by performing analysis of multiple environments. In addition to that, when development and test environments can be encapsulated and saved, the process of reconfiguration will become simple.

Christopher S is a 22 year old Caucasian male who voluntarily chose to attend the 31 day program at the Greenhouse American Addiction Center. The client was admitted to the facility dealing with opiate, cocaine, and alcohol use. His heavy drug use was compiled with feelings of stress, anxiety, and depression which stemmed from his childhood and adolescence. Over the course of his adolescence, he had many confrontations with the police and has now earned himself a pretty lengthy criminal background. He is currently facing many charges from forgery to aggravated assault with a deadly weapon. Christopher is about 5’5 with brown hair and brown eyes. Christopher reports “having a stable childhood only when he was living with his mother and stepfather, but he reports 8 years of molestation and abuse which was inflicted by his biological father which whom he had to visit in another state every summer” (personal communication,
Some faculties and departments are already using Oracle applications in their day-to-day operations. As time goes by, more and more information users will be working with an application based on Oracle database technology. If you get the opportunity to be a member of an application development team, you will become familiar with the workings of Oracle and relational databases. Other users may have to learn about this popular database management system through their own experience. This article is for our readers who, as of yet, have no access to Oracle databases but have a yearning for learning what they're all about.
Foundational Interoperability is data exchange from one system by another, Structural Interoperability is the exchange of information between systems and it is interpreted in the data field level, and Semantic Interoperability allows multiple system to exchange information (3). Currently I believe our organization is at the structural level, but our end goal of this project is to ensure we achieve Semantic
In 1977, Larry Ellison, Bob Miner, and Ed Oates founded System Development Laboratories. After being inspired by a research paper written in 1970 by an IBM researcher titled “A Relational Model of Data for Large Shared Data Banks” they decided to build a new type of database called a relational database system. The original project on the relational database system was for the government (Central Intelligence Agency) and was dubbed ‘Oracle.’ They thought this would be appropriate because the meaning of Oracle is source of wisdom.

Thin-client computing now offers real hope for progress. The state of affairs described above is like a fat pitch don the middle of home plate, just begging for thin-client computing proponents to smack it out of the park. When it comes to total cost of ownership for desktop computing services, thin-client computing is a bottom-line winner. Yes users will have to five up some control of their desktops. Any yes, administrators will need to learn a new approach to application deployment. But the payback is so clear; thin clients' arrival is almost inevitable.

Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
The database application design can be improved in a number of ways as described below:
