Protecting Your Website Database

SQL ChartIf you have a database-driven website, do not think your database does not contain data that are pleasing to eyes of hackers. All websites and databases are juicy targets. This should be your mindset to ensure vigilance against any threats to your site.

This is the reason most companies – at least businesses that rely heavily on online transactions – hire companies providing SQL server consulting services to upgrade their security protocols and make it difficult for anyone to pry into their data without their consent.

Here are some suggestions on how you can protect your website database from unwanted intrusions.

A very strong password

Using strong passwords for your website and its database is your first line of defence. While this is standard knowledge, you will be amazed at some people who settle for easier to remember passwords that leave their sites vulnerable to prying eye.

Use a combination of uppercase and lowercase letters, as well as numbers and special characters, whenever allowed, in your database passwords. While this may not be foolproof, at least it would be tough for hackers to crack.

Continuously update security software

Keeping the software that runs your website and its database updated is another defence against possible hacking attacks. Hackers are legends in looking and finding software security vulnerabilities that they can exploit to penetrate your website or database.

Employ proper parameters

Ensuring all your queries have appropriate parameters is essential when using MySQLi databases. This is because databases with improper SQL statements are easy preys to hackers. Using rogue code, hackers can get information that you stored on such database, change its tables or delete the data it contains.

All websites and their databases are targets for hackers, and it is your responsibility to protect against such attempts. There is no excuse for leaving your site vulnerable to attacks. Work hard to protect your database, because you know hackers work hard to break into your security walls.

SQL Performance Tuning: Simple Tips for the Common Businessman

by Admin - on Dec 7th 2015 - Comments Off on SQL Performance Tuning: Simple Tips for the Common Businessman

BusinessmanStructured Query Language (SQL) is commonly used to communicate with databases, and is considered to be the standard language used for relational database management systems. An SQL statement can be used to update and retrieve data from a database. Database tuning can be tricky, especially when handling large amounts of data since the smallest changes can have a great impact on the performance.

 Here are some simple SQL performances tuning tips to ensure that your business database always runs smoothly and efficiently.

  1. Blindly reusing code may not always be the best alternative. Try trimming the code to meet your current requirements for better performance and better results. Simply reusing data could also slow down the performance since it often pulls more data than really necessary.
  2. Using update blindly can also affect the performance. Instead, try using case. By testing each row for order amount conditions, this option can be used to set the ‘preferred’ label before writing it into the table. Hence: faster performance.
  3. Know when using temp tables will work. When used right, temp tables can keep you from making errors, like double-dipping. Resorting to using temp tables all the time can cause you more headache than anything else.
  4. Pre-stage data, whenever possible. Often, people overlook this step, and end up using more server resources than required.
  5. As much as you can, steer clear of correlated subqueries. These queries usually run row by row, and can greatly slow down the performance. Instead, refactoring correlated subqueries as a join.

When you have no time or the knowledge of SQL language, you also have the option of hiring professionals like DBA Services to take care of the SQL performance tuning for you.

Regularly tuning a database ensures that the search query results are displayed quickly and also that the database is not unnecessarily tied up.Choose a reputed service provider, to ensure that the job is done properly and efficiently.
