Study Notes
Metadata Repository
- Metadata is "data about data"
- Technical metadata describes how data is structured and stored
- Business metadata describes the meaning of the data
OLAP Tier
- OLAP server presents multidimensional data from data warehouses or data marts
- OLAP extensions and related tools allow for the construction and querying of cubes for data analysis
- XMLA (XML for Analysis) allows for the exchange of multidimensional data between client applications and OLAP Servers
- MDX (MultiDimensional eXpressions) is a query language for OLAP databases
- SQL/OLAP is an extension of the SQL standard to provide analytical capabilities
Front-End Tier
- Client tools allow users to access and manipulate data warehouse content
- OLAP tools enable interactive data exploration and manipulation
- Reporting tools allow for the creation, delivery, and management of reports
- Statistical tools analyze and visualize data using statistical methods
Multidimensional Model
- Data is viewed in an n-dimensional space called a data cube or hypercube
- Dimensions are perspectives used to analyze data, measures are evaluated quantitatively
- Dimensions have associated attributes describing them
- Dimension levels represent granularity or detail of measures
- Instances of dimensions are called members
- Hierarchies allow for analysis of data at different levels of detail
