If you need someone to create, manage and maintain huge databases then what you are looking for is a database architect. These highly skilled professionals are critical for the 21st century business, as a good database architect will can be critical for helping companies grow and dominate new marketplaces, while managing their business and formulating realistic strategic goals. A database architect will collaborate extensively with design analysts, software engineers and other specialized professionals to deliver optimized databases that will host thousands, even tens of thousands of users.
Of course, while the database architect constructing a glittering database wins all the glory, you also need someone to do the hard work of properly maintaining it. This is the database administrator. He needs to perform all the tasks required to make the database available as required. This means managing, backing up and making all the data accessible and available even as it is generated, processed and consumed by the employees and clients of his organization. Responsibilities of the database administrator include but are not limited to installing/upgrading database servers, allocating the physical requirements of the system, performing modifications and adaptations to conform with input from application developers and more. A database administrator may also be required to perform more fundamental database performance tuning – and in extreme cases may even call in the original database architect to pick apart the innards of the database.
database performance tuning
Like it or not, achieving and sustaining high database performance is a critical part of running goal-critical applications. Doing so requires continual database performance tuning, but what exactly is it?
Basically, database performance tuning includes every single step that can be taken to improve performance, the goal being to optimize system resource use and achieving ever greater efficiency. This is not the same of maintenance, which simply means fighting entropy and upholding the status quo. Rather, by fine tuning specific database elements including but not limited to query structure, index use, system configuration and data models, the performance of the overall system can be designed beyond the specifications of the original data architect.
