There are many different types of databases which slightly differ from one another. While DBA are general database administrators that know how handle most things, there are DBAs who are experienced in managing a specific database. MySQL DBA is a database administrator who is an expert in managing MySQL databases.
MySQL is one of the most well-known, widely used, and efficient technologies in today’s big data ecosystem. Basic knowledge of MySQL is essential for anyone involved with enterprise data or general IT, and even those who are unfamiliar with relational systems can quickly kickstart data storage systems using MySQL. The open source and relational nature of this database are its biggest advantages, being the reason for its use in both larger and smaller businesses.
That being said, and although MYSQL database is considered well documented and has a large community to support it, there are still a few things that need to be taken into consideration when using MYSQL database.
A business' database is a big and important asset and when managed correctly it can be efficiently monetized and help grow a business. But, with today's regulations and the importance of data PII for customers, misuse or data leaks can cause severe damage to a company's image which might result in revenue loss and leave your business exposed to lawsuits.
Like all SQL-based databases, MySQL has some common security issues with its sister platforms as well as a few of its own. Weak passwords, DDoS and SQL injection attacks are only some of the most prevalent security risks that come from both inside and outside of a business.
To improve resource usage and system performance in light of the complexity brought on by increasing data volume and dynamic workloads, database performance tuning and MySQL query optimization are critical.
For non-experts, SQL tuning can be a little challenging for several reasons, with the first being that writing and comprehending various execution plans requires a high level of technical knowledge. An expert with deep knowledge of SQL is responsible for writing clear and comprehensive SQL statements.
Besides its complexity, tuning is very time-consuming, as finding which SQL statements need to be tuned and which ones to leave out can be somewhat unclear when there are many of them to sort through. Every statement is unique, and each one's tuning method differs depending on the functionality it serves.
Managing backup and recovery policies are essential for every organization to guarantee durability in a case of datacenter failures, disk damage or even a malicious statement corrupting data.
Doing so in an efficient way includes taking into the equation things like the overhead included on the database instance, the length of the duration in which there is data not being backed up, recovery time in a case of failure and more.
Throughout the lifecycle of a system, database capacity planning is crucial to delivering a pre-determined, optimal and consistent experience. When adjustments to the computing environment such as the addition of more CPU, memory, storage, or network capabilities, combined with appropriate configuration changes to the application are needed, database capacity planning assists in identifying and anticipating demand.
Database management is key for running a successful business. While some businesses choose to administer their data tier infrastructure and applications themselves – the process is often complicated and holds many risks and pitfalls which can make it more costly and time consuming than expected.
