Data Warehouse Introduction

Data Warehouse is a core component of Business Intelligence and Data Analysis. It is a system used to store for data analysis and reporting. DWs acts as a central reposition which helps to keep everything in one place. Data Warehouse ensures that everything remains in one place and not in disparate sources. All current and historical data are stored in one place.

Data stored in a single place is then used for different purposes such as sales or marketing. The typical operation of a Warehouse is ETL(Extract, transform, load). Before data is stored, it is cleaned, cataloged, transformed and managed by a business professional.

History of Data Warehouse

The concept of Data Warehouse is not new, and it dates back to 1980s. Most of the works were done by the Paul Murphy and Barry Devlin as they developed the “business data warehouse.” The initial aim of data warehouse is to provide an architectural model to solve flow of data to decision support environments. Let’s list some key events in the history of Data Warehouse.

  • 1960s – General Mills and Dartmouth College, in a joint research project, develop the terms dimensions and facts.
  • 1970s – ACNielsen and IRI provide dimensional data marts for retail sales.
  • 1970s – Bill Inmon begins to define and discuss the term: Data Warehouse.
  • 1975 – Sperry Univac introduces MAPPER (MAintain, Prepare, and Produce Executive Reports) is a database management and reporting system that includes the world's first 4GL. First platform designed for building Information Centers (a forerunner of contemporary data warehouse technology)
  • 1983 – Teradata introduced the DBC/1012 database computer specifically designed for decision support.
  • 1984 – Metaphor Computer Systems, founded by David Liddle and Don Massaro, released a hardware/software package and GUI for business users to create a database management and analytic system.
  • 1988 – Barry Devlin and Paul Murphy publish the article An architecture for a business and information system where they introduce the term "business data warehouse".
  • 1990 – Red Brick Systems, founded by Ralph Kimball, introduces Red Brick Warehouse, a database management system specifically for data warehousing.
  • 1991 – Prism Solutions, founded by Bill Inmon, introduces Prism Warehouse Manager, software for developing a data warehouse.
  • 1992 – Bill Inmon publishes the book Building the Data Warehouse.
  • 1995 – The Data Warehousing Institute, a for-profit organization that promotes data warehousing, is founded.
  • 1996 – Ralph Kimball publishes the book The Data Warehouse Toolkit.
  • 2012 – Bill Inmon developed and made public technology known as "textual disambiguation". Textual disambiguation applies context to raw text and reformats the raw text and context into a standard database format. Once the raw text is passed through textual disambiguation, it can easily and efficiently be accessed and analyzed by standard business intelligence technology. Textual disambiguation is accomplished through the execution of textual ETL. Textual disambiguation is useful wherever raw text is found, such as in documents, Hadoop, email, and so forth.

Data Warehouse Tools

Data Warehouse tools enable data scientists, data wranglers, managers and anyone working with data to quickly make decisions or extract/import data. There are many open source warehouse tools one can use to manage maximum efficiency in their work process. We will list both open source tools and proprietary tools that you can use in Data Warehouse adventure.

  • Ab Initio Software: The product offers a full range of features including batch processing, data analysis, graphical user interface(GUI) based parallel processing software, etc. Their approach to data processing is evident from their 20 years experience.
  • Amazon RedShift Amazon RedShift is one of the best data warehouse solutions right now. It is managed by Amazon and falls under the Amazon web services. With Redshift, a company can easily use SQL and existing BI tools to run complex queries on petabytes of structured data.
  • CodeFutures CodeFutures Dbshards offers excellent features for database sharing. It offers scalability and the opportunity to work with traditional database platforms such as PostgreSQL and MySQL.
  • Teradata Corporation Teradata offers unique featureset for companies who want to make their data usable in a feature-set functionality. They offer analytics data platforms and other crucial functionalities required to make companies competitive.
  • Oracle: Oracle offers data warehousing service for its customers. It uses the famous Oracle 12C database to maintain performance and scalability. It follows industry standards. The company’s main platform for maintaining the warehouse functions is the Oracle Exadata Machine.
  • Cloudera:Cloudera is another major player in the data warehouse systems. It offers hadoop-based data processing and storage solutions. Cloudera’s Enterprise Data Hub(EDH) is what makes it an interesting choice.
  • MarkLogic: MarkLogic uses NoSQL database for the data warehouse solution. It recently got some attention and it was also included in the Gartner’s Magic Quadrant on DBMS.
