QlikView: Designer

I.                   Objectives

This course focuses on the basic analysis part of the QlikView tool.

It provides the basis for understanding the philosophy of the associative model proposed by QlikView and the objects that allow access to data and display it in different formats.

At the end of the course, the student will have sufficient knowledge to:

Access different types of data (both file format and structure).Create tables and graphs for analyzing information (bars, lines, pie charts, etc.).Understand the associative model of QlikView elements.

Customize the display of analysis objects.

II. Requirements

No specific requirements are needed beyond having used other simple analysis tools (Microsoft Excel, for example).

Knowledge of SQL and the use of plain text files can facilitate understanding of the subject.

III.Duration

15 hours.

IV. Methodology

The course is developed through theoretical presentation accompanied by practical demonstrations and explanations of the results obtained.

The student carries out the modeling of different data sources, to test the characteristics of the product, in addition to designing analysis sheets and control panels by inserting selection elements and graphics.

Resolution of doubts about the concepts presented.

Advanced SQL

I.                 Objectives

This course develops advanced SQL methods with both database functions (views and indexes) and specific syntax (analytics, advanced grouping, hierarchical tables, etc.).

The course uses the Oracle Database relational database.

At the end of the course, the student will have sufficient knowledge to:

Use views for data retrieval and DML restrictions. Know and use the main indexes provided by the Oracle database.

Use advanced SQL queries for efficient data retrieval in specific cases such as: data analytics, complex grouping, hierarchical tables, advanced searches, pivoting and unpivoting of data sets and multiple insertion). Elements that will be useful for different areas (data integration processes, data analysis, query performance improvement).

II.Requirements

SQL knowledge (preferably in an Oracle Database environment).

III. Duration

20 hours.

IV. Methodology
