Strengthening the Foundations of Software Architecture

  • Article

The term 'Architecture' seems to imply a plan that you can't easily subsequently deviate from. It's true that, if you abandon software architecture, you end up with a big ball of mud, but maybe the art of software is to make change much easier by planning how to implement each feature, tackling dependency issues, splitting functionality into small discrete components and considering how they should interact with each other.

Question of the Day

The Read Committed Snapshot Isolation behaviour

I am currently working with Sql Server 2022 and AdventureWorks database. First of all, let's set the "Read Committed Snapshot" to ON: 

use master;
go

alter database AdventureWorks set read_committed_snapshot on with no_wait;
go
Then, from Session 1, I execute the following code: 
--Session 1
use AdventureWorks;
go

create table ##t1 (id int, f1 varchar(10));
go

insert into ##t1 values (1, 'A');
From another session, called Session 2, I open a transaction and execute the following update: 
--Session 2
use AdventureWorks;
go

begin tran;
update ##t1 
set f1 = 'B'
where id = 1;
Now, going back to Session 1, what happens if I execute this statement? 
--Session 1
select f1
from ##t1
where id = 1;
