Flat-file database

What are some of the key differences between a flat file and a relational database? Which of the two storage methods do you think is most useful in a real-world application?

Computer Science Programming problem

Provide the analysis and pseudo code only (no diagrams are required). • Create Student Grade File • Display Contents of Grade File For each of the following problems, use the top-down modular approach and pseudocode to design a suitable program to solve it. 1. Input names of students from the user, terminated by ZZZ, and create a data file GRADES with records of the form: student (string), test1 (integer), test2 (integer), test3 (integer) In this file, all test scores should be set equal to 0. IPO Analysis 2. Display the contents of the file GRADES created in Problem 1. Each student’s record should appear on a separate line and include the total score (the sum of the thr... click for more

If the problem is simple one should use a sequential or relational file and if the problem is complex one should choose to use a database?

Suppose you wanted to keep a record of everything you own in your house. You could use a sequential data file to keep track of common items such as ‘cloths’. The sequential file may contain multiple fields with the different types of descriptions of your close such as pants, shirts, shorts, etc. If the problem is simple one should use a sequential or relational file and if the problem is complex one should choose to use a database?

Object-oriented programming Identify Top Level Objects of a Microwave

Consider a typical house in which there are several bedrooms, a kitchen, and a laundry room—each with a distinct function. You sleep in the bedroom, you wash clothes in the laundry room, and you cook in the kitchen. Each room encapsulates all the items needed to complete the necessary tasks. What you have is a set of well-defined components: Each provides a single service to communicate with the other components using simple messages when something needs to be done. If you consider a kitchen, you see it is also composed of several, smaller components, including the oven, refrigerator, and microwave. Top-level objects are composed of smaller components that do the actual work. This perspect... click for more

Identify 1 (one) task you perform regularly, such as cooking, mowing the lawn, or driving a car

Identify 1 (one) task you perform regularly, such as cooking, mowing the lawn, or driving a car: • Write a short, structured design (pseudo code only) that accomplishes this task. • Think about this task in an object-oriented way, and identify the objects involved in the task.
