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.

Here I will list the course concepts that relate to my program or what I have said in the program.
... different layers such as ETL stage, SIF, BDW and how data is processed to generate reports according to the requirement. The processing of information from raw data to different processing stages culminating in coherent information is fascinating.
In this experiment, we took a detailed look at Edward Bloom's Big Fish. In particular, we sampled 10 pages of the book, and from each of those pages, examined the number of lines starting with various types of words, and types of letters as well. In order to randomly select 10 pages from the book, we used the Vasser Stats randomizer to generate 10 random page numbers. We then went through each of the 10 randomly selected pages and recorded the number of lines that started with a noun, a verb, an adjective, a vowel, and a consonant. When recording the number of lines starting with nouns and verbs, we also made sure to divide the results into those that began with vowels and those began with consonants. The data was entered into a spreadsheet in Excel and then transferred to JMP IN. In dealing with the data, we treated each of the ten pages as an individual and so we had 10 values for the number of lines starting with each of our different word and letter types. Once the data was entered into JMP IN, we constructed 5 histograms to show the frequency distribution for the number of lines starting with each of our word and letter types. Once our histograms were created, we took a look at the descriptive statistics for each of our histograms and summarily grouped the 5 sets of data in a table. The descriptive statistics we chose to include were; the mean, median, maximum, minimum, upper quartile, lower quartile, 95% confidence intervals, and sample size. The histograms and statistics were calculated and created, respectively, in JMP. We then entered the number of noun and verb lines that started with vowels and consonants in JMP. From this spreadsheet, we used JMP to produce a contingency table. This was done to determine whether or not there exists a statistically significant relationship between the type of word and the type of letter that word begins with. Once the contingency table was created, JMP performed a Pearson chi-square test on the data.

"Although fully searchable text could, in theory, be retrieved without much metadata in the future, it is hard to imagine how a complex or multimedia digital object that goes into storage of any kind could ever survive, let alone be discovered and used, if it were not accompanied by good metadata" (Abby Smith). Discuss Smith's assertion in the context of the contemporary information environment
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.
Through this course, I gained an understanding and
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.
On joining the college, I concentrated on acquiring knowledge not only through the classroom teaching materials, but also through the volumes of Computer related materials. In the process I have acquired in-depth knowledge in the fields of Database Management Systems, Data Mining and Data Warehousing, Software Engineering especially in the concepts related to process organization and responsibilities. I was also fascinated by the growth of Networking and Communication Technology and developed keen interest in the subjects such as Computer Networks, Data Communications and Network Protocols. The Operating systems lab and Computer Networks lab unleashed a relentless desire in me to excel at its usage and find innovative applications.
Last week, I spent more than ten hours in preparation for the class; reading the Chapter, writing reflection journal, actually, it took about half the time in the search for the definitions of (Database, and Learning community).
because from some of the courses i have taken from the EDX and youtube videos, i came to know about the emerging research fields and also about the challenges faced by the current systems and system designs and i hope i can complete the theoretical part by these courses ,and can concentrate more on my research and thesis work or the work assigned by my prof...
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.
