| Hi, I am new to Database World. I have been with computers for a while and been graduate school but never had an opportunity to work with databases. So i need your advice on getting started , some good books and links, so that i get my baiscs right. In near future, i might have an opportunity to built DataWare house and data marts. So i am trying to new basics and some good practices. I have seen a post listing topics on Data Ware housing. An Introduction to Data Warehousing: Database systems -- OLTP& DSS Warehouse Architecture Staging Areas & Data Marts Data Modeling Normalization and De- Normalization Schemas Fact Tables Dimension Tables Star and Snowflake Schemas Concept of ETL ( Extract ,Transaction and Load Process ) OLAP concepts Understanding Dimensions, Details and Measures. But before getting there. What concepts i need to know about databases in general and some very specific details to built a DataWare house. Can the experts help me with this. I really appreciate all your time and help. thanks Praveen. |
