Evolution in data storage has been significant but in many ways fairly the same general approach. Flat files was one of the first ways data was stored. A database was the next evolution.Being able to take advantage of indexing data providing a means to quickly access data without having to seek through its entirety.The purpose of this article is not to take a tour through the history of the database, but please bare with me I assure you its worth its while.There was a time when the DBA was the all powerful ruler of the database and analysts as well as engineers had little control over the schema and the data at all.One major issue when dealing with big data is handling data locality. There are two different types of databases that are often mutually exclusive: OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing)./p>/p>					ul classactions>						li>a hrefhttps://dovidkopel.com/2023/12/living-data classbutton>Full Story/a>/li>					/ul>				/article>								article>					header>						span classdate>December 04, 2023/span>						h2>a hrefhttps://dovidkopel.com/2023/12/intro-to-writing-code>Intro To Writing Code/a>/h2>					/header>					a hrefhttps://dovidkopel.com/2023/12/intro-to-writing-code classimage fit>img src alt />/a>					p>/p>					ul classactions>						li>a hrefhttps://dovidkopel.com/2023/12/intro-to-writing-code classbutton>Full Story/a>/li>					/ul>				/article>								article>					header>						span classdate>December 04, 2023/span>						h2>a hrefhttps://dovidkopel.com/2023/12/interviewing-candidates>Interviewing Candidates/a>/h2>					/header>					a hrefhttps://dovidkopel.com/2023/12/interviewing-candidates classimage fit>img src alt />/a>					p>p>Over my career I’ve participated in probably over a hundred interviews.
