Database design

Non parametric tests It is a hypothesis test which does not need population distribution. For instance there are numerous hypothesis tests which depend upon assumptions that population must be normally distributed along with the parameters. Main advantages of non- parametric tests are that they do not rely on assumptions, so they can be easily used where population is non-normal. One thing to be kept in mind, that these tests may have few assumptions related to the data. They might not be…

Nelson Mandela once said, “Education is the most powerful weapon which you can use to change the world.” However, in Woody Allen’s, “The Rejection,” the writer satirizes the ideals of the education system that acknowledges only the intelligent students. This is seen in the character of Boris through his exaggerated reaction towards the failure of his son. During the time of Woody Allen, he believed that education was only for the smart and intelligent people. Woody Allen satirizes the education…

Concurrency loss due to IO path critical sections (IPCS) Time lost in waiting queue (WT) to enter a critical section affects an application concurrency (AC), and impedes the application performance from scaling (AC ∝ 1 / WT) if a workload is bursty and highly parallelized. It is apparent that the wait time to enter a critical section is a function of the CS’s size (CSS) and the number of waiting threads (NWT) i.e. WT ∝ CSS * NWT. Furthermore, the work done (IO completed) is proportional to the…

Introduction The project YrPIM was briefly introduced with a basic reasoning of its creation. This probes into details of the idea behind the project which was to create a website that can be used by middle school students who are fall in the range of 11- 14 years of age. It is assumed that by this age a student has a basic understanding of how to operate a computer since the US consensus of 2014 states that approximately 83.8% of the houses have at least one computer. Of each of these houses…

We’ve used a lot of devices and storages so far in our life, but one thing that might be weird to people is the RAID. RAID stand for redundant array of independent disks and is a place for people to store their information. It is stored on CDs, instead of the normal flash drives and hard drives. RAIDS are different from the normal CDs, because they have to divide the data and spread the blocks into several megabytes for RAID to work. This is to make RAID efficient and fast. There are lots of…

The DBA’s responsibilities include physical design, installs, security, backups, and requirements of the database. 7. The trade-offs for concurrency controls are: a. If it’s too strict it can lead to locking the entire database. b. Other measures have low level of concurrency control. 8. Atomic transaction ensures that all the actions on the database are done or none of them are done at all. If none of them are done then the database remains unchanged. It’s important because if ensures…

Chapter four Design, Implementation and Testing 4.1. Introduction: In this chapter we explain the design and implementation of the smart parking system. This explanation will include Block Diagram, flow chart and explain theoretical how the System work. 4.2. The Arduino Mega microcontroller unit: The Arduino Mega will be programed using C language to control the main system. This MC will control the gate of the parking and send all the data of all the users inside the parking faculty to the…

business databases and files were stored. Throughout the firm, multiple databases were isolated and duplicated among departments. This had caused issues, such as their subscribers receiving unnecessary marketing material, and not being able to keep the databases secure. In order for them to solve this issue was to implement and store all company data into a data warehouse using SAP NetWeaver, as well as educate their own employees on the new system to prevent further inconsistent databases. By…

Database Administrator The career I have chosen to research is database administrator. According to a report released by the U.S Bureau of Labor Statistics, “Employment of database (DBAs) is projected to grow 11 percent from the 2014 to 2024, faster than the average for all occupations. Growth in this occupation will be driven by the increased data needs of companies in all sectors of the economy”(1). The 11 percent might not seem like a lot compared to the specific field but if you really…
