Question
Chapter 4, Problem 1Q
Program Plan Intro
Fact-finding questions and Zachman Framework.
Expert Solution & Answer
Explanation of Solution
Fact finding is the means of collecting information. Five questions which help in getting facts are discussed below:
- Who? Example: Who do this? Why he/she did this? Who will do this?
- What? Example: What is the problem? Why problem occurs? What is the solution?
- Where? Where problem occurs? Where problem can be resolved?
- When? When problem arises? Why it arises there? When will it be resolved?
- How? How problem impacts the system? Why it impacts a system? How problem can be resolved?
For every question, one additional question “why” is must, which helps in clarifying the purpose of the project.
Zachman Framework for Enterprise Architecture asks questions in system development context. Over time, a framework has evolved and helps in better understanding of model and ensures proper translation of business goals into successful IT projects. It has added graphics, and better tools but the main concept remains the same: Who? What? Where? When? How? And additional “Why?”

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forward
- We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key.
