However, for databases in Azure SQL Database, the assessments identify feature parity issues and migration blocking issues for deploying to a single database or pooled database. Then, in the Add sources dialog box, select AdventureWorks2012, select Add, and then select Start Assessment.Next, on the Select sources screen, in the Connect to a server dialog box, provide the connection details to your SQL Server, and then select Connect.Thirdly, in the Data Migration Assistant, on the Options screen, select Next.And then select Create to create the project. Secondly, specify a project name, in the Source server type text box, select SQL Server, in the Target server type text box, select Azure SQL Database.Firstly, in the Data Migration Assistant, select the New (+) icon, and then select the Assessment project type.Assess your on-premises databaseīefore you can migrate data from a SQL Server instance to a single database or pooled database in Azure SQL Database, you need to assess the SQL Server database for any blocking issues that might prevent migration A summary of the required steps follows: However, you can use Azure Database Migration Service to migrate the databases from a SQL Server instance to Azure SQL Database.
#ADVENTUREWORKS2012 LOGICAL SCHEMA HOW TO#
SELECT OBJECT_SCHEMA_NAME (t.In this we will learnabout how to Migrate SQL Server to Azure SQL Database offline using DMS. In order to see how the partitioning split the records across the files and filegroups you can run this query: )WITH ( SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF , ONLINE = OFF) ON ( )Īfter configuring the partition using the above settings you can look at the table properties to see how the partition is setup. This script will modify the table to leverage the partitioning:ĬREATE CLUSTERED INDEX ON . Follow the steps to setup the partitioning and implement it on the table. In SSMS right click on the Sales.SalesOrderHeader to configure the storage for this table. Now that the partition function and partition schema are created, I need to modify the Sales.SalesOrderHeader table to leverage the newly created partition. SQL Server 2014 support up to 15,000 partitions of a table.ĬREATE PARTITION SCHEME AS PARTITION However, on the database you would need to configure the table to be a partitioned table.

The applications that perform CRUD operations continue to operate normally and do not require code changes. However, it is physically divided into 12 files in the database. In this scenario, you would have a single logical entity that represents the entire table.
You could create a partition for each month based on the transaction date by creating 12 filegroups to store the monthly partitions.
For instance if you are collecting 1 million records daily. SQL Server allows you to partition tables into smaller files and filegroups to make management and access more efficient for your large datasets. One alternative to keeping all of the data together is to split the table into smaller units. Queries and maintenance on the table and indexes will take longer to execute. If all of these records are kept in a single physical table. As the data ages, the older records generally require fewer updates. Data warehouses and data repositories often have tables that store millions of records and each day adding thousands more.
