INTRODUCTION TO DATA WAREHOUSING CONCEPTS
A data Warehousing is a database designed to enable business intelligence activities: it exists to help users understand and enhance their organization's performance. It is designed for query and analysis rather than for transaction processing, and usually contains historical data derived from transaction data, but can include data from other sources. Data Warehousing separate analysis workload from transaction workload and enable an organization to consolidate data from several sources. This helps in:
- Maintaining historical records
- Analyzing the data to gain a better understanding of the business and to improve the business
WHY DATA WAREHOUSINGS ?
Data Warehousing are distinct from online transaction processing (OLTP) systems. With a data warehousing you separate analysis workload from transaction workload. Thus data Warehousing are very much read-oriented systems. They have a far higher amount of data reading versus writing and updating. This enables far better analytical performance and avoids impacting your transaction systems. A data Warehousing system can be optimized to consolidate data from many sources to achieve a key goal: it becomes your organization's "single source of truth". There is great value in having a consistent source of data that all users can look to; it prevents many disputes and enhances decision-making efficiency.
WHO SHOULD LEARN DATA WAREHOUSINGS ?
Users of the data warehousing perform data analyses that are often time-related. Examples include consolidation of last year's sales figures, inventory analysis, and profit by product and by customer. But time-focused or not, users want to "slice and dice" their data however they see fit and a well-designed data Warehousing will be flexible enough to meet those demands. Users will sometimes need highly aggregated data, and other times they will need to drill down to details. More sophisticated analyses include trend analyses and data mining, which use existing data to forecast trends or predict futures. The data Warehousing acts as the underlying engine used by middleware business intelligence environments that serve reports, dashboards and other interfaces to end users.
SCOPE OF DATA WAREHOUSINGS?
A data mart serves the same role as a data warehousing, but it is intentionally limited in scope. It may serve one particular department or line of business. The advantage of a data mart versus a data warehousing is that it can be created much faster due to its limited coverage. However, data marts also create problems with inconsistency. It takes tight discipline to keep data and calculation definitions consistent across data marts. This problem has been widely recognized, so data marts exist in two styles. Independent data marts are those which are fed directly from source data. They can turn into islands of inconsistent information. Dependent data marts are fed from an existing data Warehousing. Dependent data marts can avoid the problems of inconsistency, but they require that an enterprise-level data warehousing already exist.
KEY CHARACTERISTICS OF A DATA WAREHOUSING
- Data is structured for simplicity of access and high-speed query performance.
- End users are time-sensitive and desire speed-of-thought response times.
- Large amounts of historical data are used.
- Queries often retrieve large amounts of data, perhaps many thousands of rows.
- Both predefined and ad hoc queries are common.
- The data load involves multiple sources and transformations.
