For who
The workshop is intended for advanced programmers and Oracle users who seek knowledge and information on the efficient development of information systems in an Oracle database, and the tuning and testing of performance issues in existing applications. This course builds on knowledge often unavailable or incorrectly presented in the technical documentation, and collected during many years of practice leading them instructors. These workshops may be the end of the training path for developers, or a single step for people with extensive experience designing and programming in Oracle
Purpose of training
The workshop aims to provide mechanisms that occur in an Oracle database when performing SQL statements. Allows participants to avoid errors during software development, and explore, diagnose, and resolve performance problems in existing applications.
Particular emphasis is placed on the workshops, where we show the methodology and the practical aspects of the application and tuning SQL statements.
The content of the training
Mechanics perform SQL commands
Managing the process cost optimization
Methods of data storage and indexing
Monitoring database performance and processes based on dictionaries and track system applications
Analysis of cases of the most common problems that cause performance
Notes
The workshops are based on the software version 11g XE
