Data Management

...University Data Management March 18, 2014 Data partitioning is a tool that can help manage the day-to-day needs of an organization. Each organization has unique values that drive business. All organizations have policies and processes that are influenced by their environment and industry. The use of data partitioning can help productivity by recognizing the need to categorize data to tailor unique needs. This approach does require some effort. To transition to a new database approach, organizations need to assess the pros and cons of a database transition. The scale of an organization’s database may be the one factor that drives an adoption of this approach. Data partitioning has been developed to address issues that traditional database queries have created. One main problem that partitioning was created to solve is the performance of database queries. According to Alsultanny (2010), “System performance is one of the problems where a significant amount of query processing time is spent on full scans of large relational tables. Partitioning of the vertical or horizontal partitioning or a combination of both is a reliable way of solving the problem” (p.273). By separating queries into either horizontal or vertical processes, the user can avoid delays and strains on a database. This saves time which can be used to improve the productivity an organization has towards their day-to-day operations. Large-scale databases receive the most benefits from partitioning. Data partitioning...

Data Management for the Internet of Things

...Data Managment During the course of an ordinary work day I took it upon myself to record all of the instances in which I was required to produce any amount of personalized electronic data. The list not only astounded me, but frightened me as well. My day started at six in the morning with a swipe of my electronic key card at my gym. The data in the key card is attached to my social security number, phone number, address, birthdate, and credit card. On my way home I stopped at a coffee shop and paid with a debit card thereby producing another record of my location at an exact time and date. At home while getting ready for work, I logged into a podcast of my favorite National Public Radio show. My login information is connected to a credit card and all of my personal demographics. The time stamp I left while streaming online radio will most likely be saved on a massive server, available for recall for years on end. As disturbing as this seems, this is only the beginning, as my day to day job requires constant surveillance, both by proximity card, audio and video surveillance. Most people can tell you that if you desire privacy at your workplace, do not pursuit a career in corrections. In one eight hour day, my proximity card, which links to my personnel record, is recorded over fifty times a day. In order to enter or exit any door or hallway, one must swipe their proximity card, which logs the activity into a massive database that is backed up into a cloud server on...
