Data Warehousing

There is a lot of confusion surrounding the term “data warehouse.” A data warehouse is simply a repository of data that is used for reporting and analysis. It can be a subset of a larger database, or it can be the entire database. The important thing to remember is that a data warehouse is designed to be used by analysts, not by operational users.

Data Mining

Data mining is a process of extracting valuable information from large data sets. It is a subset of the larger field of data science. Data science is a interdisciplinary field that deals with the collection, analysis, and interpretation of data. Data science is closely related to fields such as statistics, machine learning, and artificial intelligence.

Data mining is often used to find patterns in data that can be used to make predictions. For example, data mining can be used to predict consumer behavior, or to identify trends in the stock market. Data mining can also be used to detect fraud, or to find new ways to improve customer service.

Data Modeling

Data modeling is the process of designing and creating a model of data. The model is a representation of data that can be used to better understand, visualize, and work with data. Data models can be created for databases, data warehouses, or other data repositories.

Data Analysis

Data analysis is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, suggesting conclusions, and supporting decision-making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, while being used in different business, science, and social science domains.

Data Integration

Data integration is the combination of technical and business processes used to combine data from disparate sources into a single, coherent store. Data integration is a key component of data warehousing, business intelligence, and other data management initiatives that rely on aggregating data from multiple sources.
