Oracle Databases
A new energy is rising within CNS. Over the past year, many members of our administrative computing team have been developing Oracle applications. It is a new challenge to both CNS and our clients. We journey up the learning curve together and over the trial-and-error hurdles. Each day offers a new opportunity to understand another concept or process.
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.
What is a Database?
A database management system, or DBMS, gives the user access to their data and helps them transform the data into information. Such database management systems include dBase, Paradox, IMS, and Oracle. These systems allow users to create, update, and extract information from their databases. Compared to a manual filing system, the biggest advantages to a computerized database system are speed, accuracy, and accessibility.
A database is a structured collection of data. Data refers to the characteristics of people, things, and events. Oracle stores each data item in its own field. For example, a person's first name, date of birth, and their postal code are each stored in separate fields. The name of a field usually reflects...

Not only does Oracle allow you to link multiple tables, it also maintains consistency between them. It can prevent you from deleting a department which still has employees in it. Or if you change an employee's ID number, then all records of their work hours will also reflect that change. Ensuring that the data among related tables is correctly matched is referred to as maintaining referential integrity. This also applies to the previous example where a user enters an invalid department number for an employee. Oracle won't accept a department number that isn't in the DEPARTMENT table.
Oracle's relational databases represent a new and exciting database technology and philosophy on campus. As the Oracle development projects continue to impact on University applications, more and more users will realize the power and capabilities of relational database technology.
The common element of the open source databases is the use of share data of student information. The common features used by the databases are their operating systems UNIX or Windows, as well as MYSQL database. The database used b...
Nothing is perfect in the world of clinical systems implementation, so a Chief Informatics Officer is always on the go. He travels around the country to attend meetings in order to figure out how to best balance compliance, security, ease of use, automation of manual processes, and safety in electronic medical records systems and other hospital software systems. Clinicians have constantly evolving needs and often come to the Chief Informatics Officer with a clear idea of the problem they want to solve, but no idea of how to solve it. Reliably the pen records lessons from the meetings and concerns of clinicians as it travels with him. It crafts written reports to advise senior management on how to face the endless stream of projects, so that those which can accomplish the greatest good for the most people over the longest time period can be
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.
The Oracle Corporation is an American multinational computer technology corporation headquartered in Redwood City, California, United States. Oracle specializes in developing and selling computer hardware systems and enterprise software products – particularly its own brands of database management systems. As of 2011, the company is the second only to Microsoft in terms of revenue. The company also builds tools for database development and systems of middle-tier software, enterprise resource planning (ERP) software, customer relationship management (CRM) software and supply chain management (SCM) software. Oracle sells a large suite of business applications. The Oracle E-Business Suite contains software to perform lots of enterprise functions connected to, for instance, financials, manufacturing, customer relationship management (CRM), enterprise resource planning (ERP) and human resources. The Oracle Retail Suite covers the retail-industry vertical, supplying merchandise management, price management, invoice matching, allocations, store operations management, warehouse management, demand forecasting, merchandise financial planning and assortment planning. Users have access to these facilities through a web browser interface, over the Internet, or through their corporate intranet.
System performance is one of the most critical issues faced by companies dealing with vast amounts of data. Companies use database systems and their applications to store, retrieve and handle this data.
DBA deals with all of this by finding user needs, set the database, and test the system. DBA should enable editing any system he or she created. At the same time DBA should ensure the security of the data and guarantee data integrity and backup. Moreover, DBAs should know the database management systems (DBMS) that include the knowledge of Oracle, IBM DB2, and Microsoft SQL server (“Database Administrator,” 2010). Oracle is one of the most important platforms that DBA must know and have experience with. According to Kanaracus “The database experience we look for most of the time is Oracle”, says Tom Hart, executive vice president of the operations and technology group at Veritude. “SQL Server is more of a nice-to-have"

Since then, three Oracle programs have been initiated, and the application suite has been organized into five key processes, including one that assists in paint recipes and manufacturing processes spread seemlessly around the world. The Oracle applications allowed for globally centralized data that promotes efficiency and compliance, stimulates growth, and strengthens the bottom line.
According to Modern Database Management eight edition, by Jeffrey A. Hoffer, Mary B. Prescott and Fred R. McFadden database management system (DBMS) is define as a software system that is used to create, maintain, and provide controlled access to user databases.
Databases are used on a daily basis amongst nearly every industry in the world. Regardless of what job function you currently work you can expect that the data you are using or inputting is coming from or being stored in some type of database. To understand databases you may want to consider how they impact your career, if they are consider enterprise tools, how they are designed and the effort required to do so, and the database architecture.
The DBMS has a function that can be differentiate from the information retrieval system. The DBMS have the ability to store, update and retrieve the data. This is the main function of the DBMS because the database can be used if there is any record is being stored into the database. The record need to be retrieve first, then it can be change by the database administrator as it will be the record has been updated. The DBMS will protect the structure of the data structure.
of multiple types of end users. The data is stored in one location so that they
For more than three and a half decades, Oracle has been the leader in database software. And as it has further developed technologies and acquired best-in-class companies over the years, that leadership has expanded to into all sectors of the technology industry he started off with hardware stacks and other pieces of hardware, the company then evolved into middleware and software applications for databases and other programs and now it is starting to majorly expand within the cloud. Oracle are now advancing their te...
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
It is nothing but saving the gathered data for standard purpose in the computer. The usage of database system in a company does not provide gain rather provides raise in
