質問 # 15
What is the correct definition of a join query?
正解：C
解説：
A join in the context of a database, specifically SQL, is an operation that combines rows from two or more tables based on a related column between them. The purpose of a join is to retrievedata that exists across multiple tables which share a common field or key. The process typically involves the following steps:
1.Identify the Tables: Determine the tables that you want to join.
2.Determine the Common Column(s): Find the column(s) that the tables share, which will be used to match rows.
3.Choose the Type of Join: Decide on the type of join that suits your needs (INNER, LEFT, RIGHT, FULL).
4.Construct the Join Query: Write the SQL statement that specifies the join condition using the ON keyword.
5.Execute the Query: Run the query in the database to retrieve the combined results.
For example, if you have an Orders table and a Customers table, and both have a CustomerID column, you can join them on this column to retrieve a list of orders along with the customer information for each order.
References: The definition and explanation are based on standard SQL documentation and educational resources such as W3Schools1 and GeeksforGeeks2, which provide comprehensive guides on SQL joins.
質問 # 16
When would a business intelligence (BI) system be useful in making a decision?
正解：B
解説：
A BI system shines in this scenario because it leverages the power of data from various sources and turns that into actionable insights:
*Customer Sentiment Analysis: BI systems can incorporate natural language processing to analyze customer reviews, gauging sentiment and preferences towards organic food. Trends and patterns can be identified.
*Cost Analysis: BI can pull in data on ingredient costs (organic vs. conventional), preparing a comprehensive analysis of how switching to more organic food would impact operational expenses.
*Decision Support: By combining customer sentiment, cost analysis, and potentially market trends (through external data integration), a BI system can provide a holistic view of the trade-offs and the potential impact of increasing organic food usage.

質問 # 18
A programmer is working with C. Which type of language is this?
正解：C
解説：
C is commonly classified as a compiled programming language. In Information Technology curricula, C source code is typically processed by a compiler that translates the entire program into machine code or into object files that are linked into an executable. This compiled output can then be run directly by the operating system without requiring the original source code to be translated again each time. C is considered a high- level language compared with assembly and machine language, but it still provides relatively low-level control over memory and system resources through pointers and direct data structure manipulation. This makes it popular for systems programming, operating systems, embedded development, and performance- critical applications. Interpreted languages are usually executed through an interpreter at runtime, while machine language is binary code executed directly by the CPU, and assembly language uses mnemonic instructions that map closely to machine operations. Since C is normally translated ahead of time into executable code, it is best categorized as a compiled language. Therefore, the correct answer is compiled.
質問 # 19
What is the term used to describe additional requirements that are added after project initiation?
正解：C
解説：
In project management, scope creep refers to the uncontrolled expansion of a project's scope beyond its original boundaries. Here's a breakdown:
1.Project Initiation:
oProject initiation is the first step in starting a new project.
oDuring this phase, you establish why you're doing the project and what business value it will deliver.
oThe goal is to secure buy-in from key stakeholders based on the project's initial definition.
2.Scope Creep:
oOnce a project is underway, additional requirements or changes may arise.
oThese unplanned additions can lead to scope creep.
oExamples include:
New features requested by stakeholders.
Enhancements beyond the original scope.
Unforeseen requirements emerging during execution.
3.Impact of Scope Creep:
oScope creep can:
Delay the project timeline.
Increase costs due to additional work.
Affect quality if rushed changes are made.
Create frustration among team members.
4.Managing Scope Creep:
oTo prevent scope creep:
Define clear project boundaries during initiation.
Document requirements thoroughly.
Regularly review and assess any proposed changes.
Communicate with stakeholders about trade-offs.
