Importance of Customer Database

With more emphasis towards the use of statistical techniques, methodologies, and applications to develop models of customer behavior, attitudinal data, business patterns, future forecasts, and decision making marketers tend to be heavy users of customer Databases. Business Intelligence tools help to enhance business operations with interactive access and manipulation of data. A customer database, which is an internal database, is usually preferred than a data warehouse for marketing purposes as a data warehouse can contain a large pool of unstructured information which is irrelevant for marketing purpose and requires additional business intelligence tools for analysis. Database marketing helps target the right customers at the right time. However, a customer database carries only the relevant information in a structured format which can be retrieved or analyzed using simple queries or minimal business intelligence tools.

Difference Between Customer Database and Data Warehouse

Both Customer Databases and data warehouses work on relational data systems whereas a data warehouse is built to store large quantities of unstructured, complex historical data, a database keeps only current, structured data and uses Online Transaction Processing (OLTP) for fast access to specific transactions. Data warehouses can analyze complex queries across all data with great efficiency using Online Analytical Processing (OLAP). While a customer Database contains data only related to customers and other required data for the marketing department only, a data warehouse stores enterprise-wide data, not just limited to any one department. Customer Databases are mostly used for transactional purposes. Though analytical queries can also be performed, they are difficult to carry out due to data complexity whereas, data warehouses make analytical queries simpler to perform.


Examples of Customer Database

1. Oracle RDBMS: Companies like WalMart, Amazon, Costco and Target use Oracle RDBMS which supports multiple UNIX and Linux and Windows versions. It supports large databases, reduces processing time and occupies less space.

2. SAP Sybase ASE: This is a relational model database server product designed to meet new demands for performance, reliability, and efficiency. It has been in use in different sectors like financial services, healthcare, transportation, telecommunication, and retail industry. With the help of cloud computing and synchronization of mobile devices with the software, it can perform millions of transactions swiftly.
