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 be 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.

Main interface features

Composition of the interface :

Ribbon menu

The interface consists of a top ribbon menu of four tabs (i.e Home, Curation, Modify and Analyse) which includes the main functionalities of the portlet.

Tools area

The interface has a left side panel, which reports the main characteristics of the activated table (i.e tab properties). In also, you can visualize the list of the performed operations (once you have already manipulated your file) and if those have been successfully validated (i.e validation tab). The tab resources, lists possible operations to perform on your file (i.e export csv).

Main area

In the central panel, your active tabular resource is displayed. The picture shows on which table you are working on as confirmed by the bottom panel.

Labels

Users can change all the column labels of the tabular resource all at once using the Labels button.

Column type

this is a very important function to define the type of columns of your table and therefore properly manipulate its data. Users can define per column the column type and its attributes.

Tabular Data Manager, Column type

Tabular Data Manager, Attribute type

Add column

By specifying a label and a column type, users can add a column per time to their tabular resources.

Tabular Data Manager, Add column

Delete column

The left side panel allows to select the column to delete all at once.

Tabular Data Manager, Delete column

Merge column

Users can decide to merge two column and to create a new one. The original separated columns can be deleted or not. A new column label has to be specified.

Tabular Data Manager, Merge column

Split Column

The column of a tabular resource can be split accordingly to different criteria: 'char_sequence', 'index', and 'regex'.

Here below, an example of the application of the CHAR SEQUENCE method in the Column Split function:

Tabular Data Manager, split column and char sequence method

The original table is transformed into:

Tabular Data Manager, split column by char sequence

Here below an example of the application of the INDEX method in the Column Split function:

Tabular Data Manager, split column and index method

The original table is transformed into:

Tabular Data Manager, split column by index

Here below an example of the application of the REGEX method in the Column Split function:

Tabular Data Manager, split column and regex method

The original table is transformed into:

Tabular Data Manager, split column by regex

N.B. Value is a POSIX Regular Expression

Normalize

If you want to normalize the data in your Tabular resource, you can continue as follow:

Tabular Data Manager, normalize

Considering the structure of our table you will name a Normalized and a Value column. The system will create these two new columns at the end of the normalization.

In the pop-up setting windows, the Normalized Column will be the column containing the normalized variables, whereas the Value column will contain the values of the normalized data (i.e Normalized column: 'Year', Value column:'Quantity' and columns to normalize '1998', '1999' and '2000' )

The original table is transformed into:

Tabular Data Manager, normalize result

Denormalize

A table resource can be denormalized using the Denormalize button in the Structure menu of the Curation tab:

The original table, can be transformed by selecting the Value column and the Attribute column.

Using the normalized table of the previous section, by setting 'Quantity' as value column and 'Year' as attribute column we will obtain the original table:

Tabular Data Manager, denormalized table

Helper Menu

Extract Codelist

There is the possibility to extract a codelist from Tabular resources. Let's use the table below:

Tabular Data Manager, extract codelist

Click on the Extract codelist button, in the Helper menu of the Curation tab:

Tabular Data Manager, extract codelist button

Select the columns, for example 'code' and 'name':

Tabular Data Manager, extract codelist source column

Define the target column, for example new column:

Tabular Data Manager, extract codelist target column

Define the label and the type of your new column:

Tabular Data Manager, extract codelist target new column

The target column should appear as follow:

Tabular Data Manager, extract codelist target fill column

Choose a name for the new codelist:

Tabular Data Manager, extract codelist detail

A new codelist is extracted now:

Tabular Data Manager, extract codelist result

If you want to directly connect the tabular resource to the codelist extracted, you must set attach on detail so:

Tabular Data Manager, extract codelist attach

The original tabular resource is attached to new codelist:

Tabular Data Manager, extract codelist result by attach

Note: in this case the extracted codelist is set to final automatically.

Map Import

Modify

The modify tab includes several functions in the Table menu to work on your Tabular Resources (i.e group, add, delete, unify table etc...)

Tabular Data Manager, Modify tab

Table Menu

Union

In the Table menu, the Union button allows to relate one or more columns of your tables resources in one file.

Here below, an example of the functionality of the Union button with one tabular resources.

Selection of the files:

Tabular Data Manager, Selection of the files

Selection of the column within the table resources to unify:

Tabular Data Manager, Columns selection

The original table has been transformed into:

Tabular Data Manager, Table resulting from the Union function

A final pop-up window will inform you about the success of the union procedure.

Note: The system will report a question mark for the fields that are not involved in the union.The same if,in the selected column, there are empty fields.

Group by

In the Table menu, the Group by button allows to group the columns of your Tabular Resource accordingly to their average, counts, max, min etc...

Once selected the table to work on, the system asks to tick from the column list that one the grouping must replies on:

Tabular Data Manager, Selection of the column to apply the grouping criteria

then define the criteria, from the aggregation list, by selecting the method and the reference column:

Tabular Data Manager, Aggregation list criteria

Tabular Data Manager, Column aggregation by the selected criteria

The original table has been transformed into:

Tabular Data Manager, Result of the grouping by function

Time aggregation

The Time aggregation allows to order your data according to a time dimensional column. Before execute this function, you need to be sure that the column you want to aggregate is a time dimension type. You can modify your column by using the Column type function in the Structure menu of the Curation tab.

First select one or more columns you want to use to apply the function

Tabular Data Manager,Time aggregation for the time dimensional column

then define the criteria, from the aggregation list, by selecting the method and the reference column/s:

Tabular Data Manager, Period of time and aggregation criteria to apply on the column/s

Tabular Data Manager, Processed table results

Add row

You can add a row to your Tabular resource by clicking on the button Add row.

Delete row

You can delete a row or multiple rows in your Tabular resource by fist selecting and then clicking on the button Delete row.

Delete duplicate

You can delete duplicates in one or more columns in your table by selecting the relative columns in the column list.
