Your project will require you to develop a database design to
solve a real-life data management problem. It can be any problem in
your work environment or for another organization, for example, a
bookstore (think of how Amazon uses databases), a course management
system (think of how a university manages courses), a bank (think
of how your bank works), and an online auction site (think of how
Ebay works). You will develop a database to solve this problem
You will...
What is the difference between laissez-faire capitalism, the command system, and the market system? How does the "invisible hand" operate and why do market economies usually do a better job than command economies at efficiently transforming economic resources into desirable output?
Project Description In this project, you will design and implement a database for keeping track of information for an online “SOCIAL NETWORK” system (e.g. a simplified version of Facebook!). You will first design an EER schema diagram for this database application. Then, you will map the EER schema into a relational database schema and implement it on ORACLE or MySQL or some other relational DBMS. Finally, you will load some data into your database (via user Interface) and create some...

Overview: Database management plays an integral role in nearly every area of business. Databases house customer, accounting, and employee data, and these different data sets must all be efficiently managed in order to make the data accessible. Companies rely on database engineers to ensure that their records are accurate, updated, and tracked in real time. This course covers structured query language (SQL) and how it can be used to manage database schemas, manipulate data, and analyze data. For your final...
What is the difference between DM Type 1 and DM Type 2. Discuss the difference in pharmacologic treatment and why? Discuss the difference between the 4 different types of insulin (look at power point slides) and what each is used for. What is “insulin shock?” what are the signs and symptoms and how is it treated. Discuss how oral hyperglycemics such at Metformin work to reduce blood glucose level. What are the side effects, contraindications, and drug interactions of Metformin?...
In looking through sequence information from the first assignment, you may have noticed there was no ONE TRUE SEQUENCE, and that there were quite a few ways to present the information with different databases and multiple entries for each database. Of most importance to us right now is understanding why it matters if the sequence being described is genomic or if it was an mRNA - and if it was an mRNA – was it a splice-site variant. A) What’s...
