数据库开发 Jobs

In modern times, we are realizing more than ever that some of the most important and valuable information that a company can have is its data. We know that a company’s reputation can be compromised through a data hack or leak, and that often times, the right intellectual property can add millions, or even billions, of dollars, to the market capitalization of a corporation. As a result, companies both big and small should be doing everything that they can to keep their data safe.


Database developers work to make sure that databases where information is stored is as efficient and flexible as possible, to make sure that no matter what happens, companies can have their data safe, in any situation. The right database developer can make sure that this is done at the lowest cost possible, and also avoid storing redundant data, which obviously makes operations less productive and efficient.


No matter what, data is essential. We know that Big Data is one of the biggest technological trends in the world, because it helps to illuminate information, whether it’s regarding consumer trends or scientific research. A database developer understands the important of keeping information safe, which is essential in modern times.

I want to build a program that can read the players' screen names who I am playing against (the positions of where the players' names are displayed are always in the exact same positions on the screen, but the players are always different players as the player pool is in the 100s) and be able to create & save notes as well as view previously saved notes on specific players. Ideally, I would click on a player's name, a box would pop up (that is empty if there are no previous note), where i can read previous notes as well as create & save a note at that moment that can be viewed in a future game.
