What is staging table in informatica?
The concept of a staging table is not specific to Informatica, but is a common term used in datawarehousing and ETL. It is a database table used to store data prior to loading it into the main data warehouse tables. The name reflects that it a stage on the data's journey from source to target (rather like a staging post for a stagecoach). Typically this data would have been extracted from a source system database, and the staging table would have a structure similar to the source table. The database schema used to hold these staging tables is referred to as the staging area or the relational staging area. Data might also be stored in files prior loading in the warehouse - such files are called stage files and the directories in whch they are kept are known as the file staging area.

How Data warehousing and Data Mining is useful in terms of MIS?
Data warehousing and data mining contribute to Management Information Systems (MIS) by providing a centralized location for storing and accessing data, enabling users to run complex queries and generate reports for strategic decision-making. Data mining techniques help uncover patterns and trends in the data, allowing organizations to gain valuable insights and make informed decisions based on the information retrieved from the data warehouse. Ultimately, these tools enhance the effectiveness of MIS by facilitating more efficient data analysis and interpretation.

What is data warehousing?
Data Warehousing is the process of unifying data from multiple data sources under a single unified schema. A data warehouse is a subject-oriented, integrated, time-variant and non-volatile collection of data in support of management's decision making process.
What is the use of data?
In computing, a data warehouse (DW) is a database used for reporting and analysis. The data stored in the warehouse is uploaded from the operational systems. The data may pass through an operational data store for additional operations before it is used in the DW for reporting.A data warehouse maintains its functions in three layers: staging, integration, and access. Staging is used to store raw data for use by developers. The integration layer is used to integrate data and to have a level of abstraction from users. The access layer is for getting data out for users.This definition of the data warehouse focuses on data storage. The main source of the data is cleaned, transformed, catalogued and made available for use by managers and other business professionals for data mining, online analytical processing, market research and decision support (Marakas & O'Brien 2009). However, the means to retrieve and analyze data, to extract, transform and load data, and to manage the data dictionary are also considered essential components of a data warehousing system. Many references to data warehousing use this broader context. Thus, an expanded definition for data warehousing includes business intelligence tools, tools to extract, transform and load data into the repository, and tools to manage and retrieve metadata.
