The success of businesses is largely dependent on the integrity and accuracy of the data of their customers. The database is something most businesses and organizations use to store a large amount of data securely. The file size of the database is gigantic as they store different types of customer information.
If you’re a database administrator, one of the most important concerns for you is to make the specific pieces of data available to the authorized users. And the performance is a crucial factor so that you can make the data available. But sometimes, you might face corruption in the database of the SQL server that will not only cause inaccessibility of the data but also degrade the performance. Database corruption is undoubtedly the worst situation a database administrator can face. If you take too much time to fix the corruption, you will end up facing severe data loss.
In this article, we will discuss why database corruption in the SQL server occurs and some most effective ways to address this issue.
What Do You Need to Know about MS SQL Server?
Even though there are many reputed and reliable database software programs, the SQL server is the most effective and functional. The SQL server is one of the most well-known and popular database management systems in the world that is used by countless businesses and organizations. The excellent features and interface of the SQL server make it stand apart from the other available database software programs. Database administrators use the MS SQL server so that they can easily manage a big chunk of information and data. MS SQL server develops two databases: The MDF or primary database and NDF or secondary database.
Despite the reliability, there is one major issue regarding the SQL server that makes the database administrators go paranoid. The database files that are created by the SQL server are extremely vulnerable to corruption. Whenever the administrators face this corruption, they will end up making the database files inoperable and inaccessible.
SQL Database Corruption
Hardware failure is the primary cause behind more than 96% of SQL database corruption. The computer stores all the essential pieces of the data on the hard drive. If the hard drive crashes, the data stored in the hard drive including the SQL databases will become inaccessible. In such situations, you need to address this issue as soon as possible. Here are the common causes of SQL database corruption:
Virus Infection
Computer virus or malware is undoubtedly one of the most dangerous things. They are also one of the most common reasons behind the corruption of the SQL database. It doesn’t matter how expensive a computer you purchase, it won’t become immune to virus and malware attacks. A malware or virus can enter your computer in many ways such as through mailbox items, email attachments, web pages, malicious sites, internet downloads, etc. The database of the SQL server is extremely vulnerable to virus or malware attacks. The virus is capable of corrupting the database of the SQL server without any problem. As per the Mail Cleaner, viruses can slow down the performance of the computer.
Improper System Shutdown
This is probably the second most common cause of SQL database corruption. Despite the reason, if your system or computer turns off abruptly, you will most likely end up facing SQL database corruption. Most of the time, power failure is something that makes the computer shut down improperly. Let’s say you’re working on your SQL server. Suddenly the power goes off and your computer turns off. The SQL database file on which you were working before the shutdown will be corrupted. Hardware failure is something that can also contribute to the abrupt shutdown.
Internal Bugs
It doesn’t matter which software you download, they won’t be free of internal bugs. Due to the internal bug, the entire system or that specific software item will create an unexpected or incorrect result. Not to mention, the system or software might start behaving improperly. The SQL server of MS also comes with some internal bugs that can cause serious issues. These internal bugs of the SQL server are capable of Data Corruption in SQL Server beyond repair unless you use a third-party SQL database recovery tool.
Human Errors
Even experienced database administrators make some crucial mistakes that affect the effectiveness of the SQL server. Anything that we do wrong is known as human error. While operating your system, these errors will prove to be extremely fatal than you can ever imagine. Sometimes you might up deleting the system files unintentionally or adding corrupted data. These are human errors. Additionally, if you upgrade the SQL server improperly from the previous version, the new one might cause the SQL database to face corruption.
