When doing away with rows, columns, and tables, what is the most critical consideration to bear in mind?
Step by step
Solved in 2 steps
- What is one thing that you need to keep in mind while you are removing rows, columns, and tables?What should you remember as you fill in rows, columns, and tables?Down the left side of the table, list the four sorting algorithm names covered in Week 1. In the first column (Description), give a brief description of the algorithm. In the next column (Benefits), list some of the benefits of using the sorting method. Note: You may also include pitfalls if you want to capture some of the downside of the method. In the next column (Uses), list some organizational uses for the method. When you are done, you should have a 1-page table and a one-half to 1-page narrative of the table (a narrative is simply a description of the table in writing) that could be used as a reference piece or for a teaching tool if you were explaining sorting algorithms to someone.
- While the datamodel design process was still underway, an enterprising accountant started putting together data in a spreadsheet already. Tshepo applauded his enthusiasm, but he is worried about the integrity of the data, despite the fact that the accountant says his data is in first normal form already.
