Answer:
Difference between database and data warehouse:
| Database | Data Warehouse | |
| Definition | The database is a structured array of information that is stored, tampered with, and retrieved as needed. | Due to the broad variety of diverse types of data, you need a data warehouse for review and report generation. |
| Design | Operational database architecture is distinct from the design of data centers. When updating real-time data, it primarily observes data precision. | The data-warehouse architecture ensures a wide variety of information that is used for the purpose of research over time. |
| Focus | The database focuses specifically on transactions with the aid of queries. | It has the capacity to evaluate data that is gathered from multiple sources and to produce reports. |
| Type of Information | Information such as online seat availability is included in the databases. | The data (analysis reports) collected from the data warehouse is used to enhance and track the performance of the enterprise. |
| Types | Many forms of databases exist. OLTP, CSV, text files, excel spreadsheets and XML files are examples, etc. | It is an OLAP category of database that resides and conducts analysis on the top layer of another database. |
