Introduction to SQL Basics | Basic SQL Programming (AA-TTSQL002)

A company's success hinges on responsible, accurate database management. Organizations rely on highly available data to complete all sorts of tasks, from creating marketing reports and invoicing customers to setting financial goals. Data professionals like analysts, developers and architects are tasked with creating, optimizing, managing and analyzing data from databases ñ with little room for error. When databases aren't built or maintained correctly, it's easy to mishandle or lose valuable data. Our SQL Programming and Database Training Series provides students with the skills they require to develop, analyze and maintain data and in correctly structured, modern and secure databases.

SQL Programming Basics is a hands-on, essentials-level course that provides you with basic practical experience with Relational Databases (Oracle), SQL essentials, basic querying, working with regular expressions and basic analytics. In order to be successful in the hands-on portion of the training, it would be helpful to have some prior scripting or exposure and a high-level understanding of databases. We can tailor this agenda to suit your incoming skill level and needs. Please inquire for details.
