The field of information systems has grown and become more promising than in previous years. This increase demands highly skilled professionals to keep up with the quickly changing world of IS. Looking for a job in the Information Systems field opens the door for many disciplines, each with its significance in the business world. Most businesses need information systems skills to accomplish their goals. There is a wide selection of career options in the field of information systems. There are the technical positions, such as dealing with information management and hardware and software management, and the people-oriented technology positions, such as dealing with the design and operation of Internet applications (“Why Major,” n.d.).
One of the career options in information systems is Database administrator (DBA). In order to climb the ladder in this position, a road map should be drawn to understand each step and level. If someone is skilled in a database and wants to be an administrator, he or she must know what a prototypical job as an administrator looks like. Roles and responsibilities, stages, work force, experience,

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"
Databases always used to fascinate me from my under graduation with great curiosity to know how large data is managed and queried. This led me to do Masters in computer science concentrating in the field of Data Management. In the course of my study, I understood the concepts of DBMS which provides a robust and efficient way of managing and mining data. Through the courses like Database Systems (ITCS 6160), Knowledge Discovery in Databases(ITCS 6162) and Knowledge Based Systems(ITCS 6155) I gained enough theoretical and practical knowledge about the importance of proper organization of data, good techniques to build an efficient database management system and how well the data can be managed.
This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the DBMS, and the costs associated with implementing the DBMS.
will be made by the Database Administrator. The Database Administrator for Flix2You must have an exhaustive understanding of all areas of the business in order to be prosperous. Efficacious communication skills are essential as he or she will be working very proximately with a variety of different areas within the business. They will require to work proximately with upper management to gain a construal understanding of the business rules and to ascertain that any database solutions are consistent with the future plans of the organization. Communication with Database, Network, and Internet Security Specialists will be perpetual to preserve the security and integrity of the database. They will work with Database Operators to oversee database logs, not only to monitor activity, but withal to identify any potential issues. Application Specialists work to engender simplistic ways to sanction customers to integrate data (such as signing up for an account) and to view information (such as all movies that star a particular actor). It is consequential that the Database Administrator work proximately with the Application Specialist to ascertain that all information is precise and applications are executed efficiently. Training is another consequential area, as the DBA must edify end users how to correctly utilize the database. In additament, the DBA must oversee the backup and...
Data is very important and to keep it secure is more important, DBA has to make sure that database has enough security, they need to keep track of all database access activity and denied permission to unauthorized users. This also involves creation of new User roles, application role and maintenance of these roles.
Normalization, Integrity and Security are the important role for a DBA, Normalization helps to avoid data redundancy by reviewing data base structure at certain level. It helps to build an effective data model. Data Integrity provide some level of assurance over the information getting store and retrieved from database, DBA has to understand all DBMS features use them correctly for Data Integrity. Data Security is toughest part for DBA, auditing and multiple level security can protect data but none of them provide complete security, security can also be managed by encrypting and masking the organization data.
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.
From the diagram below show how the DBMS working. First stage is database; database is a place for structured set of data held in a computer, especially one that is accessible in various ways. For example is student name, i/c and ID, from the information the lecture can access their profile, result and other. Second stage is database management system which means the place for the data will combine together. Third stage is application program which means the all data have been separate according their functions. As example, the lecture need to know about student result just enter their information and click the result button. The information will appear. Last stage is end user which means the lecturer
Satzinger, Jackson & Burd (2010, pp. 488) further states that DBMS “provide designers, programmers and end users with sophisticated capabilities to store, retrieve and manage data”. Sharing and managing the vast amount of data needed by a modern organisation simply would not be possible without a database management system.
There are some common typed of information systems. Database management system is one of the common types of information system. It is a mixture of software and data that makes it possible to sort out and examine data. Database management system is just not for working with a particular organization
It was during the terminal phase of my salad days that I met my destiny –Computer, a wonder machine. I always believed that growing field like computers along with management would spell wonders in future. Revelations made by the use of computers in every field from basic agriculture to sophisticated industries created this confidence in me. This excited me to choose Management Information Systems as my area of study. We must have in depth technical knowledge in both computer hardware and system software to become a successful Information System’s Engineer.
Next is the DBMS as a storage which is it’s enforce data security and users privacy while using database. This is important for the multiusers database system whereby each of them might have different types of database. By having this DBMS functions, its will provide users with their individual database. Where they can access through their own items, data operation, and data that they used. This way can avoid database simultaneously.
During the last 15 years, an area has developed within the Information Systems discipline which is generally referred to as 'strategic information systems'. It concerns itself with systems whose importance to the organisation extend beyond merely assisting it to perform its existing functions efficiently, or even just effectively. A strategic information system is instrumental in the organisation's achievement of its competitive or other strategic objectives.
My interest in Information Systems Management was drawn when I was working on my final year project at Maharashtra Institute of Technology under the able guidance of the head of the Computer Engineering department. Professor R. K. Bedi’s support provided a much needed boost to my confidence in my programming skills. This new found confidence, in conjunction with the organization management skills I had acquired through active participation in extracurricular activities like “Tesla”, in inter college programming fest, made me realize I wanted to pursue a program that had comprised a blend of both the computer science and management disciplines.
Computer information system makes a system in the organizations. It is frequently termed as Information Technology. It also allows the organizations to identify how to improve the organizational system as well as promote the necessary system skills that encourage us. It is the best method to acquire knowledge of technology that I collected from several career paths. Those career paths which I continued for taking computer information systems. Design systems solutions for maintaining the organizational competence. Moreover, I chose this as my major that fits with my abilities. It depends on exploring my artistic side of knowledge in how to build the system. Jobs, certificates and salaries remained the central purposes of studying this as a major.
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.
