Data and Information Flashcards
Why is unprocessed data considered less useful?
It does not provide insights or meaning.
What is Data
Raw unprocessed facts
What is Information
Processed organized data that provides meaning or context
These are software systems that collect, process, and transform data into meaningful information
Database Applications
What is the Process Flow of DB Apps
Input Data -> DB App -> Information
Enumerate the 3 DB Architectures
- Single Monolithic Application
- Client-Server
- 3-Tier Architecture
It is a data-based application with a simpler system that is less scalable
Single Monolithic Application
What is a Client and a Server in a Client-Server Architecture
Client (DB App): Sends requests, like queries, to the server
Server (DB Server): Processes requests and returns result to the client
Architecture that separates UI from data processing. This allows simultaneous multiple-user interaction
Client-Server
A modular and scalable architecture, often used in web-based apps
3-Tier Architecture
What are the 3 layers to a 3-tier architecture
- Presentation Layer (UI)
- Logic Layer (Processing)
- Data Layer (DB)
What does it mean for information to be “complete”?
It includes all necessary details without omissions.
Why must information be “relevant”?
To meet the specific needs of the user.
What is the benefit of using a 3-tier architecture over a single monolithic application?
Increased modularity and scalability
