2- Design a system which keeps track of the jobs that it is performing an a company. • Each job is of a certain type, which is also identified by a type name. • Each job performed is given a number, a starting date and a promised finishing data. The customer of a job is noted. Any job of a given type is done in one or more steps, each of which is identified by a code and name. The steps are numbered as 1, 2, .... The average time to complete a step is also recorded. • It is possible for a given job step to be used in several types of jobs. When a job is accepted, the required steps to complete the job are scheduled and the estimated start and completion dates are recorded for each step. • What are the entities in this database and what are their attributes? What are the keys? What are the relationships and their attributes? Indicate both the cardinality and participation of each relationship. Draw an extended entity-relationship (EER) diagram for this database.

Your solution should contain: a defining diagram a pseudocode algorithm As a form of quality control, the Pancake Kitchen has recorded, on a Pancake file, two measurements for each of its pancakes made in a certain month: the thickness in mm (millimeters) and the diameter in cm (centimeters). Each record on the file contains the two measurements for a pancake, thickness followed by diameter. The last record in the file contains values of 99 for each measurement. Design a program that will read the Pancake file, calculate the minimum, the maximum and the average for both dimensions, and print these values on a report.

Computer Science UML is a standard language that allows you to capture different aspects of your system in well-defined graphical models. Some of the models capture static aspects for the system and one will capture dynamic behavior for the system. In this project, you are required to draw an activity diagram showing the actions and events involved in depositing a check to a bank account using a mobile app. In particular, your paper should provide the following: A simple pseudo-code that captures the sequence of that process A detailed activity diagram that maps to your pseudo code you identified Make sure to specify clearly any assumptions you feel important to understand your logic I'm a bit lost on what to do and really just need an example of what this is asking and then suggestions on how to go about doing the assignment.

Vocabulary Task (C language) Natural language processing (NLP) is a field of artificial intelligence that seeks to develop the ability of a computer program to understand human language. Usually, the first step of an NLP system is to convert words into numeric codes. Thus, the system converts an input text into a sequence of numeric codes before any high-level analysis. This process is known as text preprocessing. We can only perform text preprocessing if we have a vocabulary of words and their associated numeric codes. Your task is to create a vocabulary of unique words for a given text file and assign a different number from 1 to N to each unique word, with N being the total number of unique words. You must perform this assignment so that the first word in alphabetical order gets the number 1, the second word in alphabetical order gets the number 2, and so on. A word is a sequence of letters (uppercase or lowercase). The file is composed of letters and white spaces (spaces, tabs,…
Use object-oriented design where it makes sense to. Structured design is a viable option when the situation calls for it. It's unclear why things like these are happening.
A manager of a department at Google wants to schedule 15-min coffee chat between two employees every week for his 6 employees. Design and write a program to help this manager. Each employee should have a meeting with a new person. So, no meeting with the same person until they meet all the other colleagues. Use functional programming or object-oriented programing. You can have your own design to cover the requirements but you should consider a design with better time complexity. You can use any data structures (lists, dictionaries, stacks, queues, ...) The number 6 here is an example and imaging there are "n" (an even number) employees in the group (for this example n =6) Every week each employee should have a meeting and just one meeting with one person. Every week they should have a meeting with a new person. Until week 5 ( n-1 weeks) they should have a meeting with the same person. employees = [ employee_1, employee_2, employee_3, employee_4, employee_5, employee_6] It means…
please help, make the diagram very clear and make sure to use c++ terminology please. if possiible could you make the diagram handwritten :) Fish have different species, sizes, colours and favourite foods. They can swim, `blub`, and attempt to eat food (which can be successful or not—depending on what it is). Fish live in aquariums that are of particular volumes and shapes. Aquariums have different kinds of lights, gravel, and filtration technology. Fish can also fight with one another… it is all very exciting. Create class diagrams for the candidate entities in the above paragraph. You can do the UML ascii art style or submit physically.
