Overview

ADatum Corporation is a retailer that sells products through two sales channels: retail stores and a website.



Existing Environment

ADatum has one database server that has Microsoft SQL Server 2016 installed. The server hosts three mission-critical databases named SALESDB, DOCDB, and REPORTINGDB.

SALESDB collects data from the stores and the website.

DOCDB stores documents that connect to the sales data in SALESDB. The documents are stored in two different JSON formats based on the sales channel.

REPORTINGDB stores reporting data and contains several columnstore indexes. A daily process creates reporting data in REPORTINGDB from the data in SALESDB. The process is implemented as a SQL Server Integration Services (SSIS) package that runs a stored procedure from SALESDB.



Requirements

Planned Changes

ADatum plans to move the current data infrastructure to Azure.

The new infrastructure has the following requirements:

✑ Migrate SALESDB and REPORTINGDB to an Azure SQL database.

✑ Migrate DOCDB to Azure Cosmos DB.

✑ The sales data, including the documents in JSON format, must be gathered as it arrives and analyzed online by using Azure Stream Analytics. The analytics process will perform aggregations that must be done continuously, without gaps, and without overlapping.

✑ As they arrive, all the sales documents in JSON format must be transformed into one consistent format.

✑ Azure Data Factory will replace the SSIS process of copying the data from SALESDB to REPORTINGDB.



Technical Requirements

The new Azure data infrastructure must meet the following technical requirements:

✑ Data in SALESDB must encrypted by using Transparent Data Encryption (TDE). The encryption must use your own key.

✑ SALESDB must be restorable to any given minute within the past three weeks.

✑ Real-time processing must be monitored to ensure that workloads are sized properly based on actual usage patterns.
