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.
Why this course will be important to your career
Databases are all around us and by having some knowledge of how they are developed and what they can contribute to my current organization. This course will enlighten me as to the requirements necessary to personalize our databases, how they are developed and how implementing additional databases can improve my organization. While I'm not currently in a technical field I do utilize databases on a daily basis and this class will allow me to understand the finer aspects of them.
With the knowledge gathered over the coming weeks I will be able to begin branching off into another direction for my career. I have aspirations of entering the computer analyst area of Lockheed Martin and armed with this class as well as the others I have already taken and will be venturing into over the coming months, I will be able to meet my objectives. This class lays a foundation of basic database understanding and without it I will not be able to understand database concepts.
Whether Microsoft Access can be considered an "enterprise tool"
Many applications currently used in my office are from the Microsoft Office suite. We currently have no Access databases being used in my office, rather we are using SAP. I do believe we may be able to implement Access into our work center and improve our ability to share information. This being said, I do believe Access has limitations when trying to implement this program on an enterprise basis. Accessibility to multiple users simultaneously can be difficult (at least in my limited experiences). This limits the ability to use the databases across multiple offices within an organization and obviously across multiple organizations.
Microsoft Access is an excellent tool for interoffice work. Examples of this type of use from a previous organization include a Job Control or Preventive Maintenance database that allows users to track the status of maintenance activities.
Time sure does fly; in the blink of an eye, yet another 7.5-week class has come and gone. Just like life, it is scary to think that in just a few short years I will be graduating college and be in search of a future career. The magnitudes of readings, assignments, PowerPoint lectures, and videos have all contributed to the valuable knowledge I have gained since taking this course. Nothing that was presented or required was seen as invaluable towards my progression of career development. This career development course has allowed me to do some self-exploration, career research, and help me understand what influencing factors were related to the job market. Ultimately, this class helped me gauge and find a suitable career path, which will forever shape my future.
Databases and Y2K Introduction: Tremendous problems loom just around the corner for organizations that use two-digit years (i.e. 1-9-97). How tough could it be to change the year from 1999 to 2000? The "Year 2000 Problem" cannot be fixed by simply resetting a computer's internal clock on January 1, 2000. Computers may be smart, but their programmers weren't very farsighted.
Big Data is a term used to refer to extremely large and complex data sets that have grown beyond the ability to manage and analyse them with traditional data processing tools. However, Big Data contains a lot of valuable information which if extracted successfully, it will help a lot for business, scientific research, to predict the upcoming epidemic and even determining traffic conditions in real time. Therefore, these data must be collected, organized, storage, search, sharing in a different way than usual. In this article, invite you and learn about Big Data, methods people use to exploit it and how it helps our life.
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.

Big data is a concept that has been misunderstood therefore I will be writing this paper with the intentions of thoroughly discussing this technological concept and all its dimensions with regard to what constitutes big data and how the term came about. The rapid innovations in Information Technology have brought about the realisation of big data. The concept of big data is complex and has different connotations but I intend to clarify its functions. Big data refers to the concept of a collection of large and complex amounts of data that are found extremely difficult to notate or even process by most on-hand devices and database technologies.
