Database question need to create a hierarchy diagram A large business, with several medical practices, contacted your company to create a database design. You received the task to investigate if there is a need for a hierarchy based on the specifications below, and to create the hierarchy analysis if needed. You must not create the entire analysis but only the aspects related to the hierarchy as described in the instructions, class lectures and sample examples. This is the relevant fragment from the requirements specification related to your task. In the practice we have medical doctors, staff and other employees (e. g. cleaners for which we just keep contact information: name, SSN, phone). For the doctors we keep the name, SSN, phone, email, main specialty, medical school. A doctor may have appointments and write prescripions. For staff we keep the name, SSN, phone and their role (e. g. receptionist, scheduler, accountant). Based on the practice policies, some doctors are allowed to perform staff duties for a given role as needed.
The company wants to keep a log with who was working daily, between what hours and in which role. The company also wants to fast identify the role of a person in the organization (e. g. doctor, staff, ...), based on the last name or id.

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
