Database Systems and Data Management

Answer Structured data is defined as a data that are record and being filed in the database to make it can be used efficiently. frequent the case with the selection of the type of detailed data structures should be used to allow efficient algorithms can be used. Good design data structure allows a variety of critical operations carried out by using the time and little memory space, as possible. structured data will be represent in discrete form which is in column and row form. this can make the data in the database more organized.

b) DBMS (Crucial Concept): The DBMS would be responsible for all database activities (storage, retrieval, indexing, etc) and also be responsible for keeping a detailed description of the data being held. DBMS is a program that helps users to communicate with the Operating System through an interface in order to access the data from a Database in a friendly way and as soon as possible. It allows users to store retrieve and update information quick and productive. DBMS handle to recover the database in case of system error and needs to have an organized system for security issues. c) Metadata – Data that Describes Data Metadata it’s all about data being held in a Database.

Key Value Stores Looking at the different data storage models, this is the most simple to implement. This is a way to have a schema-less design for storing data. In essence, the store will act as a large hash table that is separated into keys and values (Data Access ref). To the DBMS, the values are opaque – a random assortment of 1’s and 0’s – and the application sitting on top of the database will then translate the binary to useful information. Hash functions are then used to determine where the values will be physically stored.

It was here that I discovered the qualities of perseverance and diligence in myself. I feel that these courses have done a lot to prepare me for my future studies and research work.

I feel that I am adequately prepared for that, both in having technical qualifications and the right mind-set. My interest in the field of Computer Science and my eagerness to pursue Masters in the field strengthened when I came across the University of xxxx website for Computer Science.

After 2.5 years of work experience in the IT industry, my interest has blossomed into a desire. I have a longing to delve into the sciences, which extend knowledge to this industry and make computers so ubiquitous. Following an in-depth evaluation of my intellectual interests, natural talents and potential, I have decided to pursue my graduate studies, in Computer Science. I believe, what makes me suitable for this program other than my high interest and self-motivation in the aforementioned field, is my knowledge and experience acquired over the years. I have been fortunate enough to have undergone various courses during my academic career, which have helped me build a strong foundation in my knowledge of Computer Science.

I have improved my programming skills by taking elective courses, competing in different competitions and contributing open source projects. Among these courses I took, the most interesting ones were Artificial Intelligence, Numerical Analysis, Parallel Programming, Computer Architecture and Networks. I also took online courses at various websites and attended many seminars to sharpen my skills. Since Galatasaray University attaches as much importance to mathematical courses as the programming courses, I have gained a solid background in advanced mathematics. At the 4th semester of my studies, me and my team awarded with the jury's special prize at the IBM Software Academy (2012).

Computer crashes remind students to keep your data safe in an external hard drive! To conclude this paper, I will attempt to evaluate the unique skills which I had before I started at Northcentral University and some that I have acquired since. Each skill will be categorized as a skill level of beginner, familiar or master. The majority of my skill level analysis fell in the familiar level as I do have some ability with most of the skills listed.

According to Robert Primer, the term structured data is generally applied to database while the unstructured data is applied to everything else. Mostly, the unstructured data is related to information that is not to be in column-row database and not to be stored in database. This type of data often including the text and multimedia such as email, video, audio file and photo. Nowadays, there are lots of company that use the unstructured data as it helps the company to manage their storage space including software and hardware efficiently.

Abstract Database Systems has a practical, hands-on approach that makes it uniquely suited to providing a strong foundation in good database design practice. Database design is more art than science. While it's true that a properly designed database should follow the normal forms and the relational model, you still have to come up with a design that reflects the business you are trying to model. This paper shows describes design process of database project. The importance of Completing the Design Process An important point to keep in mind is that the level of structural integrity and data integrity is in direct proportion to how thoroughly the design process is followed.

In this paper I will be discussing the differences and similarities of the three database models we have talked about in class the Entity-Relationship, Object model, and the UML modeling. First let’s look at the definition of the three models. The Entity- Relationship Model is used to visually represent data objects and is used for database design. It is easy to understand which makes it easier to communicate the design to the end user. The form used in the ER model can easily be transformed into relational tables.
