Tabular Data Manager
This is the user guide to Tabular Data Manager portlet.
Overview
Tabular data manager, is a working environment which ensures the management of tabular resources such as datasets, codelist and generic tables. Different types of data can be imported into the platform and a set of operations performed to create, explore and partially manipulate your file. Tabular Resources are used in different scientific fields ranging from statistics to signal processing and econometrics. Among the available facilities of Tabular Data Manager is the possibility to check for data correctness using codelist files, to perform aggregating and filtering operations. The main strength of the platform is the management of big dataset with more than million of data without having problems in exploring and further process your file.

Split Column
- CHAR_SEQUENCE
- For example, the Tabular Resource when splitted setting char sequence:
- is transformed in:
- INDEX
- For example, the following Tabular Resource when splitted setting INDEX:
- is transformed in:
- REGEX
- For example, the following Tabular Resource when splitted setting REGEX:
- is transformed in:
- N.B. Value is a POSIX Regular Expression
Normalize
For example, the following Tabular Resource:
when normalized setting as normalized column name 'Year', as value column name 'Quantity' and with columns to normalize '1998', '1999' and '2000' is transformed in:
Denormalize
For example, the following Tabular Resource with 'Quantity' column of type integer or numeric:
when denormalized setting as value column name 'Quantity' and as attribute column name 'Year' is transformed in:
