Draw the ERD in Chen notation corresponding to the following spec:

• Sailors are identified by an sid, having a name, age, and rating
• Boats are identified by a bid and also have a name and a color.
• Sailors reserve boats on a given date.
• Every sailor reserves a boat at some time

So I'm writing a function in javaScript that will take a user full name in one text box. "first" space "last name" But if the user does not enter the space then there should be an error. So I'm looking for a way to validate this so the user needs to enter the space.

Create tables according to the mapping. Add 2 records to each. Create 5 queries for database of 3 table joins to use most of the tables or group of tables in database. You should not have tables that are of no use.

Student(ssn, name, major)

Class(classID, name, f_ssn)

Faculty(ssn, name, office_num, dept_id)

Department(Dept_id, office_num, f_ssn)

Enroll(s_ssn, classID, grade)

Professor(f_ssn, alma-mater, tenured)

Instructor(f_ssn, term_degree, type)

Lecture(classID, method)

Lab(classID, location)

Person(ssn, dob, gender)

lines = [ { "name": "student19",
"test1": "70",
"test2": "70",
"test3": "83",
"test4": "99",
"test5": "97"
},
{
"name": "student20",
"test1": "68",
"test2": "68",
"test3": "81",
"test4": "74",
"test5": "76"
},
{
"name": "student21",
"test1": "74",
"test2": "73",
"test3": "84",
"test4": "84",
"test5": "69"
},]

I need to sort the test3 only in descending order using python lambda function.

it should look like something like this:

l_func=lambda line: here goes the function

return output=sorted(lines, key=l_func)

thanks

1)  Create a UEmployee class that contains member variables for the university employee name and salary. The UEmployee class should contain member methods for returning the employee name and salary. Create Faculty and Staff classes that inherit the UEmployee class. The Faculty class should include members for storing and returning the department name. The Staff class should include members for storing and returning the job title. Write a runner program that creates one instance of each class and prints all of the data for each object.

As always, comment the code! And please do it in Java.

A text file called coit20245.txt consists of N lines each containing a name and a family name as follows. N is largest digit of your student id number. Example of coit20245.txt file: Daniel Atkinson Rob Jackson Brian Lara Write a main() method that reads the rows of coit20245.txt and counts the lines which starts with a first letter of your name. You are to provide class comments that describe what the application does. You are also to provide comments that describe what each significant block of code does.

goal of this function will be to add an element to an already existing array in C/C++.

bool add(structure dir[], int& size, const char nm[], const char ph[]){

//code here

}

add = function name

structure = structure with two fields

{

char name[20];

char phone[13];

}

int& size = # of entries in dir

nm = name that's going to be added

ph = phone that's going to be added.

return true if entry was successfully added, false if there's no more room.

if entry was added, size will reflect the new number of entries in dir.
