TIS is a DATAWAREHOUSING application developed for the Travel & Tourism Industry which is basically a repository of an organization's electronically stored data to facilitate

reporting and analysis. This Classic or general definition focuses on data storage. 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 this system. Many references to TIS use this broader context. Thus, an expanded definition for Tourism Information System includes business intelligence tools, tools to extract, transform, and load data into the repository, and tools to manage and retrieve metadata.
