OLTP and OLAP
Organizations use database technology to store data that they collect, analyze, measure, and monitor as they conduct business. Data that is captured during transactional processes, as organizations sell products and services to their customers, is best structured in an OLTP database. Data that is used to analyze trends, key metrics, summary data, and for data mining is best stored in an OLAP database. Database designers need to understand the differences between OLTP and OLAP data and how to best design and build databases to support OLTP or OLAP requirements.
From the perspective of a Database Designer, identify the differences between Online Transaction Processing (OLTP) and Online Analytical Processing (OLAP) databases. Explain when a company would choose one database over the other and why.

Spatial Database Indexing
Includes 5 Long Answers to Discussion Question
Part of a Database Administrator’s job is to ensure appropriate information retrieval performance of their databases. End users do not and in many cases can’t wait for databases that perform slowly. This is true for many spatial databases. Consider Google Maps and the spatial data that this application stores and provides to its users. If it performs slowly, it would not provide useful driving directions. It has to perform well to be used. Slow database performance would make this application ineffective and could be dangerous or life threatening for the people who rely on it for driving directions.
From the perspective of a Database Administrator who is concerned about database performance, explain why indexing is so important when working with a spatial database.
