So I ignored the warnings about Core Data being a more difficult solution and started reading. Within three hours I had it working. I had my table array being saved in Core Data and reloading the data upon opening the app back up! The tutorial code was easy enough to adapt and I was able to have it store both title and detail arrays with only a little extra experimenting.

Q 5 (a) What is need for normalization? Define First, Second and Third Normal Form.Ans. Need for Normalization: The basic objective of normalization is to reduce redundancy, which meansthat data to be stored only once. Because storing data many times lead to wastage of space and increaseaccess time. So relation/table are to be normalized so that we can alter them at any time without doingmuch changes.

Many years ago, we dealt with a client with a very large employee table. There were thousands of employees in this organization. A few dozen among the thousands needed very specialized data in addition to the general employee data.
Large companies with massive data storage systems long ago realized they could save money on data storage by implementing an efficient data design. Imagine a large company like Amazon and how much data is stored for past and present orders as well as products listed for sale.
Some years ago, we were working with a large bank on a department-level solution. We attended a meeting in an enormous conference room that had a long wall covered in a massive ERD during that engagement. It turned out this ERD was used just for their credit card operations. The diagram had hundreds of entities and a very complex set of defined relationships. Of course, this bank employed Ph.D.'s in math and data science, and it was their job to squeeze out efficiency and minimize redundancy. In this diagram were many one-to-one relationships.
As we mentioned previously, many-to-many relationships are quite common in database design. We often discover them only after discussions with system users and management. In many cases, they are not obvious until use cases are defined, and business needs investigated.
57. There are 10 vertical and horizontal squares on a plane. Each square is painted blue and green. Blue represents the sea, and green represents the land. When two green squares are in contact with the top and bottom, or right and left, they are said to be ground. The area created by only one green square is called "island". For example, there are five islands in the figure below. Write a Python program to read the mass data and find the number of islands. Go to the editorInput:Input 10 rows of 10 numbers representing green squares (island) as 1 and blue squares (sea) as zeros1100000111100000011100000001110010001000000001110000001111100001111111100011111011000111001110001000Number of islands:5Click me to see the sample solution 2b1af7f3a8
