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…

Discuss the advantages of a database management approach to the file processing approach? Give examples to illustrate your answer. According to our text, database management is the process of storing data. In the early days of computers, they would use data resource management to store information in a specific location. This process was very inflexible and extremely costly. Instead, we use database management today. This process allows us to consolidate the data, and integrate it into many…

Teradata is basically a database that is designed to handle queries. It is a relational database management system for the world's largest commercial databases. Other RDBMS takes enormous time to process and execute the data. But Teradata RDBMS handles massive amount of data with ease. The main attraction of Teradata is its scalability, parallel processing and high performance. It generates an optimal plan for the query within few seconds. Teradata can save upto Teradata bytes in size. The…

benefit of using a relational database is that it can help the efficiency of data storage by avoiding data duplication. It is very easy to change data and the format of it which can be added or removed easily. The data can only be stored once so no more than one record change is needed. Relational databases are used to work together by primary key and foreign key as this creates a link between more than one table. By this it can use the attributes and entities within the database which makes it…

The differences in SQL and Relational Algebra are not that many. In fact, they are pretty much the same thing. Both of them have commands that need to be evaluated in order to get a result or a new table. In the SQL, we have commands that need to be followed step by step. For example, the first thing we need to know if we need to join tables. After that, we need to know what columns or fields we are putting as a result, then what table or tables are those columns coming from, and last if there…

Being and active duty member of the United States Coast Guard, I conduct multi-mission maritime services throughout the globe. I save lives, provide a safe transportation system, protect the environment, enforce laws and protect our national security. Over the years, these services have caused a demand for information system to revolutionize. These advances are needed to analyze and interpret data to coordinate responses to emergencies, track vital information and train personnel. One…

Task 9 COMPARE the usefulness of MySQL and QBE Query by example is a language used for relational databases like SQL. Its development was parallel to that of SQL’s as a database language. It was originally only able to retrieve data from a database, it was then later updated to do other operations like insert, update and delete data from a relational database. It is easier and more productive than SQL as you do not need to remember the finer details of the language as you can easily select…
