PreparationIn this assignment, you will be drawing an Entity Relationship Diagram (ERD) or Database Design Diagram.
ScenarioSuppose a local college has tasked you to develop a database that will keep track of students and the courses that they have taken. In addition to tracking the students and courses, the client wants the database to keep track of the instructors teaching each of the courses.
Instructions for the Database Design DiagramUse any drawing package or any other application you know such as Visio, Word, PowerPoint, or another tool to create the Database Design Diagram. Otherwise, you may draw the diagram by hand with a pen and paper. If you draw the diagram by hand, then take one or more pictures of the diagram with your cell phone or laptop camera, place the images into a Word document, and submit the document. Otherwise, if you use software to create the Database Design Diagram, then take one or more screen captures of the diagram, place the screen captures into a Word document, and submit the document. Submissions that are not in .doc or .docx format will not be graded. Include the following in the document:
Draw the entities of the database and the attributes of each entity, based on your research and/or common knowledge of a college and the information tracked by a college.
Create the appropriate relationships between each entity within the diagram.
Describe any assumptions that you had to make about the business rules in order to create the diagram and the associated relationships.

This course is designed for placement preparation and will mainly cover data structures and algorithms using C and C++. Even if you do not know C++, you will still be able to follow along easily. The notes will be made available as a PDF in the description below.
Data Structures and Algorithms
Data structures are used to arrange data in main memory for efficient usage while algorithms are a sequence of steps to solve a given problem. In this course, we will cover arrays, linked lists, and graphs as examples of data structures and dive into solving problems using different algorithms.
Programming Languages
C and C++ will be the primary languages used in this course but Java can also be used to implement the algorithms. I do not recommend Python or JavaScript for beginners but rather suggest learning C to get a solid foundation in programming.
Conclusion
Learning data structures and algorithms is a responsibility and I will teach this course in a way that is easy to understand for beginners. Don’t worry if you make mistakes or have trouble at first, just follow along step by step and everything will become clear.
Data Structures & Algorithms for Placements
This course is primarily for those preparing for placements or job interviews.
Time is limited when preparing for placements, so this course is structured to value your time. A 15-hour video on C with notes is available on the channel, which will be covered first. If you’re an advanced Java user or can program algorithms in Python, then it’s possible to do so. However, it’s recommended to learn C and C++ first.
Data structure is an arrangement of data in main memory, which refers to RAM (Random Access Memory) of 2, 4, 8, 16, or 32 GB. The sequence of RAM usage is important when loading a program like “chrome.exe” for Windows. Fiddling with data occurs in main memory, which must be arranged optimally using data structures to minimize RAM usage.
The theory of databases is not covered in this course, but you should know their basic concepts. When opening a new tab, a large amount of data is stored in a database that must be retrieved and updated regularly. Data warehouses store data permanently for faster retrieval and updation for analysis purposes. Legacy data needs to be stored separately from the main system.
Sorting Algorithms
The example used here is sorting arrays in ascending or descending order. An algorithm is a series of steps to create a process. When sorting an array, steps must be taken to sort in ascending or descending order. The steps taken to sort an algorithm into an array d
efine the algorithm.

Data analytics is a process in which data is collected from various sources, cleaned by removing irrelevant information, and transformed into meaningful insights. This involves the use of technologies, tools, and frameworks to analyze the data and extract valuable information.
The data generation process is constant and only expected to increase in the future. With the advent of newer technologies, the data analytics domain holds paramount importance in every sector. Companies are constantly looking for professionals who can convert data into crucial insights.

Introduction to Data Structures
Welcome to Gate Smashers! We will be discussing what data structures are and their applications.
What are Data Structures?
Data structures are a way of organizing and storing data in a computer so that it can be accessed and used efficiently. They are essential for efficient algorithms and program design. Examples of data structures include arrays, stacks, queues, linked lists, trees, and graphs.
Applications of Data Structures
Database management systems
Compiler design
Operating system design
Artificial intelligence and machine learning
Computer graphics
Code Example: Stack
Here’s an example of a stack implemented in Python:
class Stack: def __init__(self): self.items = [] def push(self, item): self.items.append(item) def pop(self): return self.items.pop() def is_empty(self): return len(self.items) == 0 Conclusion
Data structures are essential for efficient programming and algorithm design. By understanding and utilizing data structures, we can create more efficient and effective programs.

What is Data Structure?
Data structure refers to anything stored in digital form on a computer. It can be a piece of text, an image, a video, or any other type of data. However, in computer science, the term “data structure” specifically refers to the way data is organized and stored in a computer program.

Read Before Starting this Assignment:
You must complete Exercise 8-1 to do this exercise.
When in doubt, refer to and modify the SQL codes in Exercise 8-2.
Keep in mind that the database server will NOT keep a copy of your SQL codes. The database server simply executes the commands that you send from your client (Workbench). Therefore, in Workbench, please save your SQL codes as SQL script files (*.sql). The *.sql files will become your template for later exercises or a backup.
o Common practice is to place all create-table commands in one *.sql file and all insert-data commands in another *.sql file.
