In computing, a data warehouse (DW, DWH), or an enterprise data warehouse (EDW), is a sysem used for reporting and data analysis. Integrating data from one or more disparate sources creates a central repository of data, a data warehouse (DW). Data warehouses store current and historical data and are used for creating trending reports for senior management reporting such as annual and quarterly comparisons.

Different types of systems:

Data Mart: A data mart is a simple form of a data warehouse that is focused on a single subject (or functional area), such as Sales, Finance, or Marketing. Data marts are often built and controlled by a single department within an organization. Given their single-subject focus, data marts usually draw data from only a few sources. The sources could be internal operational systems, a central data warehouse, or external data. http://docs.oracle.com/html/E10312_01/dm_concepts.htm

OLAP (On Line Analytical Processing) is characterized by relatively low volume of transactions. Queries are often very complex and involve aggregations. For OLAP systems a response time is an effectiveness measure. OLAP applications are widely used by Data Mining techniques. In OLAP database there is aggregated, historical data, stored in multi-dimensional schemas (usually star schema). OLAP would have data latency typically in few hours as opposed to data mart where latency is expected to be closer to one day. OLTP (On Line Transaction Processing ) Also called Decision Support Systems is characterized by a large number of short on-line transactions (INSERT, UPDATE, DELETE). The main emphasis for OLTP systems is put on very fast query processing, maintaining data integrity in multi-access environments and an effectiveness measured by number of transactions per second. In OLTP database there is detailed and current data, and schema used to store transactional databases is the entity model (usually 3NF).

Predictive Analysis: Predictive analytics is about finding and quantifying hidden patterns in the data using complex mathematical models that can be used to predict future outcomes. Predictive analysis is different from OLAP in terms of OLAP is focused on historical data analysis and is reactive in nature while Predictive analysis is focused on future. These systems are also used for CRM (Customer Relationship Management)
