Match the following terms with their correct definitions:

Rate of Change Split = A process performed to optimize storage consumption or reduce query costs in some systems Table Compression = An alternative to rate of change split that is recommended in some cases Optimize Storage Consumption = One of the main purposes of performing rate of change split Reduce Query Costs = Another main purpose of performing rate of change split in some systems Signup and view all the answers

Match the following actions with their correct descriptions:

Performing Rate of Change Split = A process that can be done to optimize storage consumption or reduce query costs Using Table Compression = An alternative method that can be used instead of rate of change split Optimizing Storage Consumption = A result achieved by performing rate of change split or using table compression Reducing Query Costs = Another result achieved by performing rate of change split or using table compression Signup and view all the answers

Match the following statements with their correct interpretations:

Rate of Change Split is performed to optimize storage consumption = A true statement about the purpose of rate of change split Table Compression is the recommended alternative to performing rate of change split = A true statement about the alternatives to rate of change split Rate of Change Split is performed to reduce query costs in some systems = A true statement about the purpose of rate of change split in certain scenarios The recommended approach for rate of change split is to use table compression = A statement that suggests the preferred method for rate of change split Signup and view all the answers

Match the following terms with their correct definitions in the context of rate of change satellite split:

Rate of change = The speed at which data in a satellite table changes over time Satellite table = A table that contains the descriptive attributes of a business entity Rate of change satellite split = A technique for splitting a satellite table into two or more tables based on the rate of change of the data Data Vault = A data modeling and database methodology that is designed to provide long-term historical storage of data Signup and view all the answers

Match the following scenarios with the appropriate rate of change satellite split strategy:

Customer data = Split into two satellite tables: one for data that changes frequently, and one for data that changes rarely Product data = Split into three satellite tables: one for data that changes frequently, one for data that changes occasionally, and one for data that changes rarely Employee data = Not suitable for rate of change satellite split as all attributes may have different rates of change Sales data = Split into multiple satellite tables based on the rate of change of different attributes Signup and view all the answers

Match the following steps with their correct order in the process of rate of change satellite split:

Step 1 = Identify the attributes in the satellite table that have different rates of change Step 2 = Create a new satellite table for each rate of change Step 3 = Transfer the corresponding data from the original satellite table to the new satellite tables Step 4 = Update the ETL processes and queries to work with the new satellite structure Signup and view all the answers

Match the following benefits with the appropriate action in rate of change satellite split:

Improved performance = Splitting a satellite table into multiple tables based on the rate of change of the data Reduced storage requirements = Creating separate satellite tables for data with different rates of change Easier data analysis = Having dedicated satellite tables for data that changes at different rates Simplified data querying = Working with smaller and more focused satellite tables Signup and view all the answers

Match the following attributes with their expected rate of change in a rate of change satellite split:

Shipping address = Frequently changing Name = Rarely changing Contact information = Frequently changing Date of birth = Rarely changing Signup and view all the answers

Match the following data entities with their appropriate rate of change satellite split strategy:

Sales data = Split into multiple satellite tables based on the rate of change of different attributes Inventory data = Not suitable for rate of change satellite split as all attributes may have different rates of change Customer data = Split into two satellite tables: one for data that changes frequently, and one for data that changes rarely Supplier data = Split into multiple satellite tables based on the rate of change of different attributes Signup and view all the answers
