Randomly distributing attributes across records: To randomly distribute attributes across members, we will use RANDBETWEEN() to assign each member a random integer between 1 and 100.Alternatively we can use the RANDBETWEEN() function to generate random integers within a given range. This expression even works for decimal and negative bounds. To generate random values within a given range, we can use the expression LOW + RAND()*( HIGH-LOW), where LOW and HIGH are the range bounds. Generating random numbers: In Excel, to generate random numbers we will use either the RAND() or RANDBETWEEN() functions.When building our custom attributes, we will typically use two techniques: We will use Excel to build these attributes, though we could instead use the mathematical functions in MySQL. Then we will create additional attributes which will allow us to build our fact tables. For our member dimension we will keep the company name, city, state, type (public/private), and category (sector). To build our member dimension, we will start with an existing list of companies with various attributes about those companies. We use an arbitrary high date of to represent coverages that are currently being offered. Next, we create our line of coverage dimension, which includes the coverage name and the start and end dates for when the coverage was offered. #EXCEL DUMMY DATA GENERATOR CODE#Thankfully, code already exists for many databases to build a date dimension. Your dataset will have member, line of coverage, and date dimensions with monthly revenue and budget facts.Ī date dimension will help us build our fact tables. Using this information, you construct a simple data model that you will base your demo dataset on.
