It can be downloaded for free from CodePlex.ĪdventureWorks has replaced Northwind and Pub sample databases that were shipped earlier. Microsoft SQL Server comes up with the sample database called AdventureWorks which is NOT installed by default with SQL server installation. If you are learning SQL Server you will come across many blogs, articles and training videos using sample database called AdventureWorks explaining and practicing database concepts with SQL Server technologies. I will be posting more about the concepts mentioned above as dedicated post. Have a look at the AdventureWorks OLAP schema. Below is the typical star schema strucutre: Star and Snowflakes schemas are the database design structures for OLAP databases to store data in the form of dimensions and measures. OLAP databases have different types (ROLAP, MOLAP, HOLAP) and I will be covering them later in my blog as a separate post. Various ETL tools are available in the market SSIS is one of them. What you get in the end is a data which is made perfect for reporting and separate from production OLTP so that performance of production system is not impacted while reports are running.ĮTL (Extract, Transform and Load) is the process that is used to extract the data from multiple database sources, transforming that based on the business rules and then loading them into the OLAP databases for reporting purposes. The data might go into some staging tables for cleansing before loading them into the OLAP database structure. OLAP (Online Analytical Processing) databases are extracts of one or more OLTP databases and are created for complex reporting, trend analysis and dashboards for decision making.ĭata is extracted from multiple OLTP sources using the ETL processes that run during off-peak hours.
If you want to see a complex diagram of a system then have a look at AdventureWorks OLTP schema. The typical diagram of OLTP database looks something like below:
Usually the OLTP data models are complex and hard to understand.

Each entity is broken down into table(s) to store the data in an optimal way and to prevent data redundancy and data update anomalies. The data is kept in a normalized structures (3NF). Since OLTP databases are used by the production systems therefore response time is very critical (< 1 second) to give better user experience. OLTP (Online Transaction Processing) databases are operational databases designed to keep the day-to-day business data transactions in the most optimal way by support faster queries, faster inserts, minimal locking and avoiding duplicates.
If you heard someone talking about databases then they are mostly “99.9%” of the times talking about the OLTP databases.
