Friend or foe? SQL Server views have been a subject of heated debates when I was in my first year using SQL Server. They said it was bad because it was slow. But how about today?
Are you on the same boat as I was many years ago? Then, join me on this journey to unravel the real deal about SQL views so that you can write them the fastest possible.
Read MoreWe often see poorly written complex SQL queries running against a table or tables in databases. Those queries make the time of execution very long and cause consuming huge CPU and other resources. Still, complex queries provide valuable information to the application/person running them in many cases. Therefore, they are useful assets in all varieties of applications.
Read MoreFacing an SQL Server performance issue, you need to identify the source of that performance problem fast. Therefore, a tool for tracking the current workload and detecting the bottleneck issues without causing extra load is necessary.
Read MoreThis document records steps, scripts, and ideology behind the maintenance performed on a production database between 22nd April 2015 and 23rd April 2015. The details are specific to an application, but the principles may be useful to others in need of doing similar operations in production.
Read MoreRelational databases follow the ACID properties in how they implement transactions – Atomicity, Consistency, Isolation, and Durability. Isolation is necessary to ensure that multiple transactions can’t cause changes to data and leave the eventual results inconsistent. To guarantee that the operations remain isolated, SQL Server applies Locking mechanisms.
Read MoreDatabase backups, integrity checks, and performance optimizations are core regular tasks of DBAs. The client data is very important for a DBA to manage the database backup and make sure the integrity of the backups. So if something goes wrong with a production database, it can be recovered with minimum downtime. The database integrity checks are also important because, in the case of database corruption, it can be corrected with minimum downtime and data loss. Managing database performance is also important. Managing database performance is a combination of multiple tasks. Read More
The database is a critical and vital part of any business or organization. The growing trends predict that 82% of enterprises expect the number of databases to increase over the next 12 months. A major challenge of every DBA is to discover how to tackle massive data growth, and this is going to be a most important goal. How can you increase database performance, lower costs, and eliminate downtime to give your users the best experience possible? Is data compression is an option? Let’s get started and see how some of the existing features can be useful to handle such situations.
In this article, we are going to learn how the data compression solution can help us optimize the data management solution. In this guide, we’ll cover the following topics:
Before deploying your application into production, doing a performance load test is imperative for measuring future performance and ensure that your application is production-ready.
Testing is essential for every application to make sure that any application works and performs according to the desired requirements. During the application testing process, we can attempt and find out if any imperfections are remaining in the application. There are numerous sorts of testing like functional testing, unit testing, acceptance testing, and integration testing. We compose Functional and UI tests to see whether the application is working as per the requirements. Read More
There are a number of situations which would warrant the movement of database files or transaction log files from one volume to another on the same server. These may include:
Performance monitoring and troubleshooting in SQL Server is a vast topic. In SQL Server 2005, dynamic management views, also known as DMV’s, have been introduced and became an essential helping tool for diagnosing SQL Server performance problems. At the same time, we can use dynamic management views for Azure SQL Database. Some of them can differ from SQL Server on-premise database but the logic of work is still the same. Microsoft has very good documentation about dynamic management views. The only thing, you need to be careful about the version and product validation of dynamic management views. Read More
