How does a decision support system differ from a transaction processing system? List the steps involved in data processing. How does a data warehouse support in the decision making process?
Understand the Problem
The question is asking for an explanation of how a decision support system differs from a transaction processing system, as well as the steps involved in data processing and how a data warehouse supports the decision-making process. This implies a focus on information systems and their functions in an organizational context.
Answer
DSS focuses on decision-making, TPS on transaction processing. Data processing steps: collection, input, processing, storage, output. Data warehouses consolidate data for complex analysis aiding in decision-making.
A Decision Support System (DSS) aids in decision-making through data analysis and simulations, while a Transaction Processing System (TPS) focuses on processing routine transactions quickly and accurately.
Data processing steps typically include:
- Data collection
- Data input
- Data processing
- Data storage
- Data output
A data warehouse supports decision-making by consolidating and organizing large volumes of data from different sources, enabling complex queries and analysis.

More Information
DSS analyzes complex, non-routine decisions, using techniques such as 'what-if' scenarios. TPS handles frequent, daily transactions like billing and inventory management. Data warehouses enhance analytical capabilities, allowing businesses to identify trends and patterns.
Tips
A common mistake is confusing the purpose and functionality of DSS and TPS. Remember, DSS is for decision support, and TPS is for operational transaction handling.
