Database performance and maintenance
Performance in a database is more than adding a few indexes. Whilst it’s possible to have too few, it’s also possible to have too many. Or more simply that they need maintenance. The design, where it’s hosted and on how powerful a computer also play a role and this is why you need experts. After all why pay for more computing power if you can restructure your queries and remove unnecessary maintenance tasks?
However, it’s not always apparent where future performance and maintenance issues can come from. Many database products will perform quite adequately, even with a badly designed database, until the volume of data and queries reaches some critical mass. As requirements change and data volumes grow, it’s necessary to improve on, extend or even rebuild what you have. Conversely you may need to review how data gets into the system.
Regardless, slow processes result in slow teams and a slow business.
A well designed database is performant, easy to maintain and easy to plan for scale. This allows a business to access accurate data information, to respond quickly to the market and take advantage of faster reporting and analysis. It makes better, more informed decisions.
