So they need information system that is subject oriented, integrated, non volatile and time variant. Data warehouse is the viable solution. It is integrated repository of data gathered from many sources and used by the entire enterprise. In order to standardize data analysis and enable simplified usage patterns, data warehouses are normally organized as problem driven, small units called data marts. Each data mart is dedicated to the study of a specific problem. The data marts are merged to create data warehouse. This paper discusses about design and integration of data marts and various techniques used for integrating data marts. Keywords - Data Warehouse; Data Mart; Star schema; Multidimensional Model; Data Integration __________________________________________________________________________________________________________ I. INTRODUCTION A data warehouse is a subject-oriented, integrated, time variant, non-volatile collection of data in support of management’s decision-making process [1]. Most of the organizations these days rely heavily on the information stored in their data warehouse.

Computer scientists have been develop- ing techniques for preserving data integrity during trans- formation since the 1970s (Doan, Halevy, and Ives 2012); however, we agree with the authors of (Breiner, Subrah- manian, and Jones 2018) and others that these techniques are insufficient for the practice of AI and modern IT sys- tems integration and we describe a modern mathematical approach based on category theory (Barr and Wells 1990; Awodey 2010), and the categorical query language CQL2, that is sufficient for today’s needs and also subsumes and unifies previous approaches. 1.1 Outline To help motivate our approach, we next briefly summarize an application of CQL to a data science project undertaken jointly with the Chemical Engineering department of Stan- ford University (Brown, Spivak, and Wisnesky 2019). Then, in Section 2 we review data integrity and in Section 3 we re- view category theory. Finally, we describe the mathematics of our approach in Section 4, and conclude in Section 5.

As time goes by, these organizations produce a lot of data related to their business, but often these data are not integrated, been stored within one or more platforms. Thus, they are hardly used for decision-making processes, though they could be a valuable aiding resource. A central repository is needed; nevertheless, traditional databases are not designed to review, manage and store historical/strategic information, but deal with ever changing operational data, to support “daily transactions”. 3/80 Andrea Brunello Data Warehousing What is Data Warehousing? Data warehousing is a technique for collecting and managing data from different sources to provide meaningful business insights. It is a blend of components and processes which allows the strategic use of data: • Electronic storage of a large amount of information which is designed for query and analysis instead of transaction processing • Process of transforming data into information and making it available to users in a timely manner to make a difference 4/80 Andrea Brunello Data Warehousing Why Data Warehousing? A 3NF-designed database for an inventory system has many tables related to each other through foreign keys. A report on monthly sales information may include many joined conditions.
