Assignment 1: Business rules and Data Models CIS 111: Introduction to Relational Database Management Systems Purpose of Database Spellman University had requested that I develop a database for their college. The purpose of the database will be to track the students and the courses. There also will be a place in the system to track the instructors teaching each course. There are many things to be considered in composing this database. This paper will outline the entities, attributes for each entity

THE MAJOR TOPIC OF THIS DATABASE IS TESTING (DRUG TESTING) STATEMENT OF WORK: TESTING DATABASE PROJECT HISTORY A hospital is conducting a double blind test of a new depression drug. The test is expected to take into consideration 20 doctors and about 400 patients to be tested. It is planned that half of the patients will get the new drug and half will get traditional Prozac and neither the doctors nor the patients will know who is getting which drug and at what time. The test is organized such that

There are two last things we are interested in: security and performance. Since both systems are widely used in the world, we do not worry about their ability to keep the database system secured. On the other hand, studying their performances would be a good indicator for making our decision. By executing several SQL query statements and monitoring the execution and CPU utilization, memory utilization, virtual memory utilization and threads used, here is an example of the measurement data: The

Introduction: In this report I am going to explain what a database is, features of a relational database, and the benefits of a relational database, purpose of primary keys and how they are used to build relationships, and I am also going to focus on, what are foreign keys and how they are been used, explain referential integrity and finally, how to apply referential integrity. I am also going to backed up my views and opinions with the valid references. Assessment introduction Iain’s & Co is a

The following represent the key reasons for companies to implement NoSQL databases in their critical line of business applications. 5.1 Amazon Response times directly impact customer satisfaction and revenue thus are more important today with businesses having many competitors just a click away. NoSQL solutions like Apache Cassandra have the ability to write data faster and deliver compared to RDBMS. Amazon found that every 100ms decrease in site response time gave them 1% more in revenue. 5.2 Ooyala

data is called big data and the insights from big data can help examine trends, understand customer preferences and help the organizations take better decisions which results in better customer service and effective marketing. Relational Database Management Systems (RDBMS) provides an efficient way for storage and processing of data but have limitations when it comes to handling Big Data. Apache Hadoop is an open source framework and its helps in the distributed processing of Big Data. Hadoop

objective of the document is to detail the steps necessary to implement a Big Data database platform to achieve what is called an Enterprise Data Lake and to improve Enterprise Data Hub where all data stored in one place and integrated with existing infrastructure and tools. Relevance Presently, I am working as a Database developer in a Software company. My primary role is to help my clients in implementing appropriate database architecture and analyzing data so that my clients can understand their users

A DBMS can also provide many perspectives of a single database schema. A perspective characterizes what information the client sees and how that client sees the information. The DBMS gives a level of reflection between the reasonable diagram which characterizes the legitimate structure of the database and the physical construction that portrays the records, files and other physical instruments utilized by the database. At the point when a DBMS is utilized, frameworks can be adjusted all the more
