Business Intelligence (BI) refers to the technologies, processes, and tools used to collect, analyze, and present business data to support decision-making. BI transforms raw data into actionable insights, enabling organizations to make data-driven decisions.
Data Warehousing: A centralized repository for storing integrated data from multiple sources. Example: Amazon Redshift, Google BigQuery.
ETL (Extract, Transform, Load): A process for extracting data from sources, transforming it into a consistent format, and loading it into a data warehouse. Example: SSIS, Talend, Informatica, Pentaho.
OLAP (Online Analytical Processing): A technology for analyzing multidimensional data. Example: SSAS, SAP BusinessObjects.
Dashboards: Visual displays of key metrics and performance indicators. Example: Tableau, Power BI, QlikSense
Reporting: Generating structured summaries of data for analysis. Example: Crystal Reports, SSRS.
Data Sources: Databases, APIs, spreadsheets, cloud storage, IoT devices. Example: Sales data from a CRM system, website traffic data from Google Analytics.
Data Integration: Combining data from multiple sources into a unified view. Example: Using ETL tools to integrate sales and marketing data.
Data Storage: Storing integrated data in a data warehouse or data lake. Example: Storing customer data in Amazon Redshift.
Data Analysis: Processing and analyzing data to uncover insights. Example: Using SQL queries to analyze sales trends.
Data Visualization: Presenting data in visual formats like charts, graphs, and dashboards. Example: Creating a sales dashboard in Tableau.
Data Governance: Ensuring data quality, security, and compliance. Example: Implementing access controls and data validation rules.
