1. Introduction
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.
2. Data Management
2.1 Database
As defined by Kroenke Database is an integrated, self-describing collection of related data. Data is stored in a uniform way, typically all in one place- for example, a single physical computer. A database maintains a description of the data it contains and the data has some relationship to other data in the databa...

...gement to the advanced level topics. I added to my knowledge about the use of Databases, Knowledge Discovery in Databases and the role database plays in maintaining authentication, confidentiality and integrity. The courses like KDD and KBS were challenging as majority of concepts under KDD are still under research and have not come to practice yet.
The references are mentioned below. Apart from the course work, I had chance to interact with many students and professors which helped me in gaining lot of knowledge and confidence.

The first database systems were based on the network and hierarchical models. A database can be defined as a collection of non-redundant data which can be shared by different application systems. A database implies separation of physical storage from use of the data by an application program to achieve program/data independence. Using a database system, the user or programmer or application specialist need not know the details of how the data are stored and such details are usually "transparent" to the user. .
What did you learn from this course? List at least 5 of them and discuss how you plan to use them for your work/home/relationships.
My thought about this course that I was expecting so far , was that it’s going to be easy. But a little bit challenging and it’s exactly what I thought. It’s also very organized, to make it easier to find all the weekly content, discussions, assignments and quizzes. They have the categories labeled so you can know what items go with the lesson. The most useful success/study strategies I applied during week 1 was to first read over the lesson and objective , also the announcement to get an head start of the lesson to be able to know what to expect to learn. After I read of objectives and the rest, I will take the knowledge practice problem to learn what I may know and don’t know to work on. The most interest concept covered so far all of week
Here I will list the course concepts that relate to my program or what I have said in the program.
For this coursework two kinds of data models can be used. The object oriented data model, Object Oriented Database Management System(OODBMS), or the relational data model, Relational Database Management System(RDBMS). The differences between these two models and the data model to be used are described in this chapter.
The fascination about information management, the seminar on ‘Hadoop vs RDBMS’ as well as the exposure to data-ware housing made me realize the need of a concrete base in MIS. My long term goal is to conduct research in the field of Information Systems and I look forward to develop my career in the field of MIS and a graduate degree at University of ______, _______will be the right step in that direction.
The reason for the selection of this topic is because it falls under the computer science category. We have been studying databases for four years and so the this topic area will be of great use when venturing into the cooperate world.
RDBMS remains for Relational Database Management System. RDBMS information is organized in database tables, fields, and records. Each RDBMS table comprises of database table columns. Every database table line comprises of one or more database table fields. RDBMS store the information into the accumulation of tables, which may be connected by basic fields (database table sections). RDBMS additionally give social administrators to control the information put away into the database tables. Most RDBMS use SQL as database query language
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.
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.
Database systems play an important role in our daily lives, and the need to be used in various fields of life in the present day are
My past projects centered around analyzing, formulating and delivering solutions in every stage of providing Microsoft-format software for major Fortune500 companies. I have also designed a database system (implemented in SQL Server) and developed front end applications in Visual C++ and Visual Basic that used ODBC and DAO to access the server. This work piqued my interest in doing research in the field of database systems, and I started to think more analytically about the limitations of relational databases. I became interested in object-oriented databases, particularly their flexibility and their ability to meet the requirements of more complex structures. In my graduate studies, I plan to focus my research on optimizing queries and improving the performance of complex systems such as image, engineering, or scientific database systems.
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.
The awareness and understanding given by this course are empirical. For example; To approach any problem, we need to have some knowledge and understanding about it. Then, we can combine those interpretations to find a best possible solution to the issue and this particular skill comes from the study of philosophy. And throughout my educational and professional career I am bound to face many of these problems and after taking this class I am self-sufficient to solve these problems.
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
