(BI) Using MS Excel Powerpivot
2018 ASCUE Proceedings Developing an Introductory Class in Business Intelligence (BI) Using MS Excel Powerpivot Dr. Sam Hijazi Trevor Curtis Texas Lutheran University 1000 West Court Street Seguin, Texas 78130 [email protected] Abstract Asking questions about your data is a constant application of all business organizations. To facilitate decision making and improve business performance, a business intelligence application must be an in- tegral part of everyday management practices. Microsoft Excel added PowerPivot and PowerPivot offi- cially to facilitate this process with minimum cost, knowing that many business people are already fa- miliar with MS Excel. This paper will design an introductory class to business intelligence (BI) using Excel PowerPivot. If an educator decides to adopt this paper for teaching an introductory BI class, students should have previ- ous familiarity with Excel’s functions and formulas. This paper will focus on four significant phases all students need to complete in a three-credit class. First, students must understand the process of achiev- ing small database normalization and how to bring these tables to Excel or develop them directly within Excel PowerPivot. This paper will walk the reader through these steps to complete the task of creating the normalization, along with the linking and bringing the tables and their relationships to excel. Sec- ond, an introduction to Data Analysis Expression (DAX) will be discussed. Introduction It is not that difficult to realize the increase in the amount of data we have generated in the recent memory of our existence as a human race. To realize that more than 90% of the world’s data has been amassed in the past two years alone (Vidas M.) is to realize the need to manage such volume. -

Identity Columns
Guide to Using SQL: Identity Columns A feature of Oracle Rdb By Ian Smith Oracle Rdb Relational Technology Group Oracle Corporation 1 Oracle Rdb Journal – Identity Columns The Rdb Technical Corner is a regular feature of the Oracle Rdb Web Journal. The examples in this article use SQL language from Oracle Rdb V7.1 and later versions. Guide to Using SQL: Identity Columns There have been many requests for Oracle Rdb to generate unique numbers for use as PRIMARY KEY values. In Rdb 7.1 we chose to implement two models that capture the functionality of most SQL database systems on the market and reflect the current planning for the draft SQL Database Language Standard. CREATE SEQUENCE and AUTOMATIC columns The identity feature described here is closely related to two other features of Rdb V7.1: the automatic columns, and the create sequence statement. Identity combines these two features into a simple package for creating table specific unique values. The current draft SQL database language standard, informally called SQL:200x, defines identity as an internal sequence generator. This implies that the associated sequence is not stored in the system tables and has no private name. That is, it is not an explicitly named schema object such as that created using create sequence, instead a sequence is implicitly created when the identity clause is applied to one column of a table. The IDENTITY syntax is currently quite simple. IDENTITY [ (start-value [, increment]) ] Note: In the future it is likely that Rdb will extend this syntax when the final SQL:200x standard is published. -

Columnar Storage in SQL Server 2012
Columnar Storage in SQL Server 2012 Per-Ake Larson Eric N. Hanson Susan L. Price [email protected] [email protected] [email protected] Abstract SQL Server 2012 introduces a new index type called a column store index and new query operators that efficiently process batches of rows at a time. These two features together greatly improve the performance of typical data warehouse queries, in some cases by two orders of magnitude. This paper outlines the design of column store indexes and batch-mode processing and summarizes the key benefits this technology provides to customers. It also highlights some early customer experiences and feedback and briefly discusses future enhancements for column store indexes. 1 Introduction SQL Server is a general-purpose database system that traditionally stores data in row format. To improve performance on data warehousing queries, SQL Server 2012 adds columnar storage and efficient batch-at-a- time processing to the system. Columnar storage is exposed as a new index type: a column store index. In other words, in SQL Server 2012 an index can be stored either row-wise in a B-tree or column-wise in a column store index. SQL Server column store indexes are “pure” column stores, not a hybrid, because different columns are stored on entirely separate pages. This improves I/O performance and makes more efficient use of memory. Column store indexes are fully integrated into the system. To improve performance of typical data warehous- ing queries, all a user needs to do is build a column store index on the fact tables in the data warehouse. -
