History of Data Warehousing


The concept of data warehousing dates back to the late 1980s  when IBM researchers Barry Devlin and Paul Murphy developed the "business data warehouse". In essence, the data warehousing concept was intended to provide an architectural model for the flow of data from operational systems to decision support environments. The concept attempted to address the various problems associated with this flow - mainly, the high costs associated with it. In the absence of a data warehousing architecture, an enormous amount of redundancy was required to support multiple decision support environments. In larger corporations it was typical for multiple decision support environments to operate independently. Each environment served different users but often required much of the same data. The process of gathering, cleaning and integrating data from various sources, usually long existing operational systems (usually referred to as legacy systems), was typically in part replicated for each environment. Moreover, the operational systems were frequently reexamined as new decision support requirements emerged. Often new requirements necessitated gathering, cleaning and integrating new data from"data marts" that were tailored for ready access by users.

Data warehouses are computer based information systems that are home for used data that originated from any another application or from an outer system or source. Warehouses optimize database query and reporting tools because of their capacity to analyze data, often from disparate databases and in interesting ways.

First and foremost the movement to data warehousing was a consumer driven movement. Some technology trends are vendor and product driven. Other trends are consumer driven. Characteristic of a vendor and product driven marketplace are a few well defined products that have a broad range of functionality. Characteristic of a consumer driven market place are lots of technologies, where the consumer takes what is already in place and adapts that technology to suit the needs of the consumer. Consumers have to knit together different technologies to achieve the effects they want. Data warehouse in that regard is definitely a consumer driven marketplace.

In the early stages only two vendors within the IT industry foresee what was happening later become data warehouse.  A data warehouse is a relational database that is designed for query and analysis rather than for transaction processing. It usually contains historical data derived from transaction data, but it can include data from other sources.
