Introduction to Oracle Data Mart Builder

Product Overview z Major components of Oracle Data Mart Suite yDesigner:Data Modeling yBuilder: Data Populating yDiscoverer: Data Analysis

Data Mart Lifecycle Data Modeling (Designer) Data Populating (Builder) Data Analysis (Discoverer)

Designer: Data Modeling E-R diagram (OLTP) Empty Tables (Data Mart) Star Schema (Data Mart)

Builder: Data Populating zManage the flow of data from sources to the target data mart tables. yExtraction: define and select tables and columns you want from the source (SQL Query) yTransformation: calculation, aggregation, rename etc. yTransportation: load data into data mart

Builder: Data Populating zTypes of sources supported by Builder yFlat file: xfixed length: flat file with fixed length for each field xcharacter separated: flat file with fields separated by characters yRelational database: Oracle, Sybase, Informix, SQL Server etc.

Populating steps zPopulate dimension tables zPopulate time dimension tables zPopulate stage table zPopulate fact table

BaseView and MetaView zA BaseView is a graphical representation of all or a portion of a physical database, including the tables, columns, and joins. zA MetaView is the view you use to start building your data flow plans. Database BaseViewMetaView
