A hybrid cloud is a combination of on-premises infrastructure and cloud services, allowing for greater flexibility and optimization of workloads.
What is multi-tenancy vs. single-tenancy in cloud computing?
Multi-tenancy refers to multiple users or organizations sharing the same cloud infrastructure, while single-tenancy involves dedicated resources for one user or organization.
What is dynamic scaling in cloud computing?
Dynamic scaling allows cloud systems to automatically adjust resources (e.g., storage, processing power) based on demand.
What is information granularity?
Information granularity refers to the level of detail of information, ranging from detailed to summarized data.
What are the three characteristics of organizational information?
The three characteristics are:
1. Accuracy
2. Timeliness
3. Relevance
What is master data management (MDM)?
MDM refers to the process of ensuring consistency, accuracy, and accountability of an organization’s critical data across different systems.
How does MDM impact corporate governance?
MDM helps ensure data integrity, reduces errors, and enhances decision-making, contributing to better corporate governance.
What are two categories of information types?
The two categories are operational and analytical information.
What are the five characteristics of high-quality information?
The five characteristics are:
1. Accuracy
2. Timeliness
3. Relevance
4. Completeness
5. Consistency
What are the four primary traits that help determine the value of information?
The four primary traits are:
1. Accessibility
2. Accuracy
3. Consistency
4. Timeliness
What is metadata?
Metadata is data that describes other data, providing information about the data’s structure, content, and context.
What are data elements?
Data elements are the smallest units of data that can be individually stored and processed.
What is a primary key in a database?
A primary key is a unique identifier for a record in a database table.
What are integrity constraints in a relational database?
Integrity constraints are rules that ensure data accuracy and consistency, such as primary keys and foreign keys.
What is a logical view in a database?
A logical view is how data is presented to users or applications, independent of its physical storage.
Can a database support multiple logical views?
Yes, a database can support multiple logical views, allowing different users to access the data in different ways.
What is a data-driven website?
A data-driven website is one that uses a database to manage and display dynamic content based on user input or interaction.
What are the advantages of a data-driven website?
Advantages include better data management, customization, and the ability to dynamically update content.
What does it mean to be data-rich but information-poor?
It means having access to a large amount of data, but not being able to extract meaningful insights or actionable information from it.
What is business intelligence?
Business intelligence refers to the use of data analysis tools and techniques to make better business decisions.
What is distributed computing?
Distributed computing is the use of multiple computers working together over a network to perform complex tasks.
What is the difference between a traditional blockchain token and an NFT?
A traditional blockchain token represents a digital asset or currency, while an NFT (Non-Fungible Token) represents a unique, non-replaceable asset, often associated with digital art or collectibles.
What are network providers and network categories?
Network providers are companies that offer internet or network services, while network categories refer to the type of network (e.g., LAN, WAN, MAN).
