Data Analysis

The main goal of the proposed NBS Online Data Analysis Portal is to allow for dissemination of statistical data with a wide range of functionalities.

The major components of this portal are the following:

NBS Data Warehouse
The data warehouse is a query-intensive environment. At any time, different users of the NBS Data Warehouse might be executing multiple, big or small, queries to perform all types of data analyses. Part of the value of a data warehouse is to provide optimal data accessibility and manipulation.

Web based Data Portal
NBS Data Portal is built on a web-based platform. It contains five components: Maps, Data Analysis, Reports, Dashboards and Resource Center. The modules are described below.

Maps Module
The modules purpose is to display geographical indicators on a map. When a user selects an indicator and additional selections in other dimensions (e.g. time, measure, flow etc.) map regions are colored according to available data values.

The indicators displayed on the map page are selected from the NBS data. When a user hovers over the map, the selected indicator values are reflected on the map. When a user selects a region/district on the map, the regions data are displayed accordingly on a chart and in a table.

The module includes the National map. The data used on this module are connected to the NBS Data warehouse. Whenever data is updated in the warehouse, the data displayed on the map module is simultaneously updated as well.

Data Analysis
To give analyst-level users a complete hands-on feel on all available data collected, we provide the Data Analysis module within the NBS Online Data Portal. This module makes use of the OLAP (Online Analytical Processing) technology, an efficient analytical tool for performing multi-dimensional queries on various data sets, with resulting display exportable to external formats.

Via the Data Analysis module, users can easily, on the fly, interact directly with the data to create an explorer view that best meets their needs. By dragging and dropping dimensions from one component to another and selecting any set of locations, any period(s) of time frame, any indicator(s) of their choice, users can conduct custom analyses effortlessly and visualize the results in table and chart form.

The Data Analysis module allows for flexible retrieval of available data to fit each users needs. For example, if education indicators are involved: a specialist using the NBS Online Data Portal can choose to view multiple data series (ex. primary, secondary, and tertiary enrollment ratio) for a particular location; a development partner might choose to analyze trends across time and provide assessment updates; a government official might want to monitor literacy rate, poverty head count, public spending on education, and conduct location comparisons; a policy analyst might compare indicators across recent years to measure the effectiveness and impact of an education initiative.

Also, the Data Analysis module would support all key features of multidimensional data technology: "slice and dice," "drill down," "roll up." We allow users to pivot tables, filter data, highlight cells according to specific conditions, and perform some statistical analysis. They would also be able to save their existing queries for later use. The results of user queries can be printed, saved and/ or exported to appropriate Microsoft Office products, Adobe products, and/or other common file types.

Using convenient and presentation-ready graphical representations of information collected from the data warehouse, our reports make all data interpretable at a glance. Not only that, our reports can come with predefined texts and graphics that are dynamically linked to the data warehouse. As the data updates, the information displayed will refresh accordingly. The NBS Online Data Portal contains a default set of pre-defined reports, based on a preliminary list of data sources.

Users of the portal can directly review and access a set of pre-defined reports in convenient tables and charts format. These are pre-defined analytical reports that highlight the most requested data chosen by the NBS team. Users can also print directly from the application or export into various common file formats for distribution purposes.


This module provides a snapshot of specific preselected indicators. Various types of dashboards can be introduced to allow users to perform comprehensive analysis on both the global and regional levels. Users can also look at dashboards to compare indicators across topics/themes, sources, time, and location.

Resource Center
Numerous organization and country publications (including reports, publications released by major government organizations and trade associations, reference files, etc) are made available to users via the NBS Online Data portals Resource Center.
