Editorial - Serverless Software |
|||||||||||||||||
I love the words "loosely coupled." At times in my career, I've built software and have aimed to ensure that processes, workflows, and components worked well on their own. In the places where I had to work with data or services on different physical machines, I tried to ensure that each item would run separately, and communicate when needed, but wouldn't fail if another machine was down. That's kind of the idea proposed in the article that says the future of software is serverless? It's an interesting read, talking about the advances in cloud services that can change the way developers build applications. Developers should think about liking services, and pieces of applications, ignoring the idea their systems are tied to specific servers. It's a future that I think makes sense for most environments. Development shouldn't be concerned about the size or care of physical machines. Instead they should think about building on a platform of services, and expecting the scale to grow or shrink as needed, without code changes. I do think this could be the future in which development proceeds inside companies, as well as for commercial software. However vendors need to sell "private clouds" which function in the same way as the public ones, for those companies that want to control, and invest in, their own hardware. » Join the debate, and respond to today's editorial on the forums The Voice of the DBA PodcastsWe publish three versions of the podcast each day for you to enjoy.

Yesterday's Question of the Day |
|||||||||||||||||
USE tempdb
CREATE TABLE dbo.MyTable
(
MyTableID INT NOT NULL IDENTITY (1, 1),
SomeText VARCHAR(100)
);
INSERT INTO dbo.MyTable
(SomeText)
VALUES ('qwerty');
DBCC CHECKIDENT ('dbo.MyTable', RESEED, 100);
INSERT INTO dbo.MyTable
(SomeText)
VALUES ('uiop');
SELECT MyTableID
FROM dbo.MyTable;
Which two values are returned? Assume this is SQL Server 2012. Answer:
Explanation: SQL Server 2012 BOL for CREATE TABLE - http://msdn.microsoft.com/en-us/library/ms174979(v=sql.110).aspx The Identity "seed" is the value used for the very first row loaded into the table. In the example code the first row inserted received an identity value of 1. When supplying a new RESEED value the rules about which value will be issued next change depending on whether there are rows in the table when DBCC CHECKIDENT with RESEED was issued. SQL Server 2012 BOL for DBCC CHECKIDENT - http://msdn.microsoft.com/en-us/library/ms176057(v=sql.110).aspx DBCC CHECKIDENT ( table_name, RESEED, new_reseed_value ) Current identity value is set to the new_reseed_value. If no rows have been inserted into the table since the table was created, or if all rows have been removed by using the TRUNCATE TABLE statement, the first row inserted after you run DBCC CHECKIDENT uses new_reseed_value as the identity. Otherwise, the next row inserted uses new_reseed_value + the current increment value. |

Grouped Failover, a 2008R2 version of Availability GroupsOne of the new cool features in SQL 2012 is the SQL Server Availability groups. In other words being able to failover a group of databases which are logically connected. i.e. SharePoint databases. Well, it is also possible to do that in SQL 2008 (R2). It’s called a Grouped Failover. More » |
