A data professional would like to combine multiple data sources into a relational database to improve their business efficiency.
Which data integration initiative can help them achieve this?

  1. Manually collect the data from various source interfaces, then clean and combine the data into one warehouse.
  2. Use a middleware application that acts as a mediator to normalize data and bring it into a master data pool.
  3. Create a data warehouse to run queries, reports, and analyses to retrieve data in a consistent format.
  4. leverage data lakes to manage complex and massive volumes of structured and unstructured data.

Answer(s): B

Explanation:

A middleware application is a software that acts as a mediator between different data sources and data consumers. It can normalize data and bring it into a master data pool, which is a centralized repository of consistent and quality data. This can help a data professional to combine multiple data sources into a relational database to improve their business efficiency. A middleware application can also provide data integration services such as data transformation, validation, cleansing, and enrichment.
