SQL Operations Studio Dashboards

SQL Operations Studio is a free tool that runs on Windows, macOS, and Linux, for managing SQL Server databases.

I have a great experience running this tool on Linux CentOS and you can build server and database management dashboards  like below.dashboard02dashboard03

What is Stretch Database?

Stretch Database is a feature of SQL Server where data can be split between on-premises storage and cloud storage. With Stretch Database, cold, historical data is kept in the cloud and active data is kept on-premises for maximum performance.

Stretch Database requires no changes to client applications or existing Transact-SQL queries, so you can implement it seamlessly for existing applications. Stretch Database can reduce on-premises storage requirements both for data and associated backups. Backups of on-premises data are smaller and therefore run quicker than standard backups. Data in the cloud is backed up automatically.

With Stretch Database, cold historic data remains available for users to query, although there might be a small amount of additional latency associated with queries.

Implement a Stretch Database
You can implement Stretch Database entirely within SQL Server Management Studio; you do not need to pre-configure servers or storage within Microsoft Azure.
Implementing Stretch Database involves the following steps:

  1. Start Microsoft SQL Server Management Studio and connect to the instance of SQL Server.
  2. In Object Explorer, expand Databases.
  3. Right-click the database, point to Tasks, point to Stretch, and then click Enable.

After implementing Stretch Database, you can monitor it from SQL Server  Management Studio.

In Object Explorer, expand Databases, right-click the stretch-enabled database, point to Tasks, point to Stretch, and then click Monitor to open the Stretch Database Monitor. This monitor shows information about both the local and Azure SQL instances, along with data migration status.

Thinking in Sets

Thinkins in sets is a great book by Joe Celko’s. This book tell us about concepts how we need to think when we were working with databases.
Columns are not fields, rows are not records and tables are note files, hence SQL is declarative, not procedural. There is no sequential access or ordering in table, so “first,” “next,”
and “last” rows are totally meaningless.
I agree when he write “One of the first things that a newbie does is use a proprietary autonumbering feature in their SQL product as a PRIMARY KEY”. This is completely wrong, and it violates the definition of a relational key.
An attribute has to belong to an entity in the real world being modeled by the RDBMS. Autonumbering does not exist in an entity in the real world being modeled by the RDBMS. Thus, it is not an attribute
and cannot be in a table, by definition.
That’s how I think and was totally wrong before.

So lets do something sets!
