Main principles, components, requirements

19.04.2005 MSIS, Bratislava, Slovakia 2

Strategies developed by:

•Experts from the NSI•Local experts •Assisted by EU experts •National Phare Technical Assistance Project


Strategy for development of ISIS and IT Strategy

Interrelated documents;Common scheme:

- Main objectives and tasks,- Current situation;- What to be achieved – components,

architecture, principles;- Requirements and constrains;- Consistency development.


The purpose of the Strategy for Development of

ISIS

to define the essence, architecture, leading principles, main directions and stages of the ISIS development and implementation using contemporary information technologies


Conclusions concerning the current situation

“stove-pipe”-system;

Documentation of the statistical work on paper;

Procedures and technologies are in dependence on the expert’s experience;

Many different databases for statistics storage

Limited standardization;

Use of administrative sources – in embrio;

Collection of metadata – without SW application and approved standard;

Statistical Business Register – outdated SW and technology.


I S I S – general definition

Centralized DB-s centrally maintained;

Decentralized services

Composed of components

Standardization of the procedures in the statistical activities;

Metadata driven system – common definitions, terminology, management rules, relations, functionalities in common MD base.


I S I S – architecture

Functional components:- Planning and design of statistical surveys;- Data collection;- Data editing;- Data processing;- Statistics (statistical data) production;- Dissemination of statistical products and services.

Infrastructure components:- Metadata base;- Statistical registers;- Data from administrative sources.

Databases: Observation registers, Final observation register, Macrodata base Dissemination database


I S I S – architecture

Integration in ISIS by standardisation of: Information;Technologies;Organization of the ISIS elements.

Shared databases

Multi-layer system


I S I S – functionality (1)

Planning and Design of the Statistical Surveys Component SW application for detailed standard description of

statistical survey; creation of catalogues of questionnaires, definitions,

variables; questionnaire design; standard procedures in the statistical survey; methods, control algorithms, processing description; MD collection in Metadata base for common use



Data Collection Component

Data Editing Component

Data Processing Component

Dissemination of Statistical Products Component



Metadata Base Component core infrastructural ISIS component; metadata collected for the statistical survey system metadata; system management rules and regulations; unified conceptual data-model for all metadata; object-oriented approach and flexible database

model;

Statistical Registers ComponentData from Administrative Sources Component


ISIS Development Principles Conformity with the law Standardization and integration of ISIS components Guaranteeing the interests of the independent partners within ISIS Security of the system Openness in terms of system environment Adaptability Continuity Gradual realization


Necessary conditions for ISIS development and functioning

General regulation of work on and concerning the ISIS functionality, in compliance with approved rules for ISIS organization, governance and security. General organization requirements relevant to ISIS management Financial requirementsIT requirements


IT requirements

included in the IT Strategy as migration rules;

Strong dependence between development of ISIS and IT environment


Consistency of ISIS development and implementation

ISIS - gradually developed depending on funding priority development of some infrastructural components within 18 months. The metadata component could be developed after development functional components.The NSI Intention - in the 4-5 years period to develop all components and achieve a real integration.


Experience gainedgood organization and collaboration in the statistical office and the developing company

The integration is based on the common data model in different information systems;

The integration requires a clear definition of the inherent services in every one of the integrated systems and a performance of all “separate” systems, as their own functionality;

Involve responsible experts from the statistical units in the development process of the systems


IT Strategy principles

An IT Strategy has the same structure as the Strategy for Development of ISIS. The Strategy of IT development in NSI contains basic assumptions relevant to the targeted IT environment and IT management structure. The fundamental principle when establishing the future IT environment is to achieve a maximum reasonable consolidation of the currently heterogeneous IT resources.


Requirements concerning the structure, range, quality parameters and system

functionality are based on: Requirements derived from ISISAn analysis of the currently existing IT environment in NSI;The necessity to change the IT organizational and management structure;The current trends in development of the IT environment components;Requirements aiming at optimization of the organization and management of the IT environment.The necessity to ensure the IT security;The achievement of financial efficiency and investments protection;The adoption of good practice of developed statistical institutions.


Obligation to follow and ensure the application of the

principles: Assuring the functional requirements of ISIS components.Centralized control of resources;Centralized services;Operational compatibility with the e-government information systems;Independence when taking a technological decision;Compatibility;Expandability
