Updating your database development skills to
More data has been collected in the past two years than in the entire human history. It’s a truly exciting time in the data world with new approaches to data collection, manipulation and types of databases.
departments, and by extension, their organizations overall.
The DBA is the person who manages, backs up and ensures the availability of the mountains of data produced and consumed by today’s organizations via their IT systems.
Data access can then be optimized by use of indexes, which read like a book’s table of contents.
DBAs help to ensure that the database is optimized to take advantage of the physical or virtual hardware on which it is hosted.
For instance, when a user enters a customer name and clicks to display their bank account balance, the database returns the correct amount and not, say, the loan balance.
They likely work with business analysts and others who are intimately familiar with banking operations to design the various application’s functions and modules.
There are also database administrators who create and design databases in the first place.However, for smaller, single-company databases a non-specialist DBA is usually sufficient.A third type of database administrator is the Application DBA.In the commercial bank example we used earlier, the bank most likely purchases or leases the software to run its banking operations from an Information Communication and Technology (ICT) company that specializes in banking software.This banking software is underpinned by a database, which is the backend storage for all the data, and that was designed and built by a team of specialist DBAs (more properly called ‘database designers’).Every day, we create an estimated 2.5 quintillion (that’s a 1 with 18 zeros, just FYI) bytes of data, and this amount is accelerating at an exponential rate. Without the database and ability to query the database, it would be nearly impossible to analyze any of that data in a meaningful way.
