Data abstraction and data independence are two key concepts in computer science and database management systems. They are closely related and aim to improve the efficiency, flexibility, and maintainability of data management.
What is data abstraction and data independence?The definitions of these two are:
Data Abstraction:
Data abstraction refers to the process of hiding the implementation details of data and providing a simplified view or interface to interact with it. It allows users to focus on the essential aspects of data without being concerned about the underlying complexities. In programming languages, data abstraction is often achieved through the use of abstract data types (ADTs) or classes.
By abstracting data, programmers can create high-level representations of data entities, defining their properties and operations.
Data Independence:
Data independence refers to the ability to modify the data storage structures and organization without affecting the higher-level applications or programs that use the data. It allows for changes to be made to the database system without requiring corresponding modifications to the applications that rely on that data. Data independence provides flexibility, scalability, and ease of maintenance in database systems.

Find the following series of 8,88,888,8888,88888
the sum to n terms of the sequence 8, 88, 888, 8888,..... is 80/80(10ⁿ-1) -8/9n
How is this so?The nth terms is solved as follows
Sⁿ =8+88+888+8888+......+n terms
= 8/9 [9+99+999+9999+....to n terms]
= 8/9 [(10−1)+(10² −1+(10³ −1)+(10⁴ −1+....to n terms]
= 8/9 [(10+(10²+(10³ .....n terms) - (1 + 1 + 1 + ....n terms)
= 8/9 [(10(10ⁿ-1))/(10-1) - n] [Sun of GP= a(rⁿ-1)/(r-1) when r > 1]
= 8/9 [ 10 (10ⁿ -1)/9) -n]
= 80/81(10ⁿ -1) -8/9n
Thus, it is correct to state that 80/81(10ⁿ -1) -8/9n

Imagine you're an Event Expert at SeatGeek. How would you respond to this customer?
* Hi SeatGeek, I went to go see a concert last night with my family, and the lead singer made several inappropriate comments throughout the show. There was no warning on your website that this show would not be child friendly, and I was FORCED to leave the show early because of the lead singer's behavior. I demand a refund in full, or else you can expect to hear from my attorney.
Best, Blake
