A historical essay: Harmonious Approch

The Machine Screw

  • Principle discovered around 400 BC

  • Limited use until machine tools made mass production possible (18th cent.)

  • Every machine shop and foundry made unique sizes and thread dimensions

  • 1841: Joseph Whitworth presented “The Uniform System of Screw-Threads” to Britain’s Institute of Civil Engineers

  • 1864: William Sellers proposes “On a Uniform System of Screw Threads” to the Franklin Institute, Philadelphia

  • Enabled interchangeable parts and tooling for mechanization and mass production

  • 1945: British and American standards merged


Point-to-point integration Harmonious Approch

of data

Merge results

  • Application includes subprogram

  • to each different data source

  • Operations on data must be

  • processed by an application

    • Lots of coding efforts

    • Fully dependent of

    • data resources


Data Warehouse Harmonious Approch

  • Data are loaded in the database

  • Data need filtering, cleaning,

  • transformation

  • Data must be refreshed

    • Scripts must be written

    • Timeconsuming to refresh data

    • Up-to-date data can not be

    • guaranteed

ODBC - JDBC


ODBC – JDBC and more Harmonious Approch

Federated data

  • Data stay untouched

    • Integrates

    • heterogeneous local or

    • remote data sources

    • through wrappers

  • Just need to know what

  • data should be available

  • to whom and how to access them

  • It makes all data look

  • like it is one virtual database

  • hiding the data layer complexity


Ontologies Harmonious Approch

  • Controlled vocabulary means

  • only one controlled term is used for a given concept

  • Data Model:

    • Data structuring mechanism in which an ontology is expressed

P Harmonious Approch3G Knowledge Database

Knowledge Curation and Information Technology

  • The advantages of integrating databases in different aspects of Biobanks as public resources.

  • The first requirement that has to be fulfilled to enable biobank communication is a unique identity for each biobank

  • Second, a common nomenclature is needed in order to communicate between biobanks.


P Harmonious Approch3G Knowledge Database

The potential impact of integrating will be:

  • Promote communication within and between major biobanking initiatives thereby helping to overcome existing fragmentation of population genomic research.

  • Enhance the effective sharing and synthesis of information, thereby addressing the need for very large sample sizes and helping to promote collaborative international genetic epidemiological and clinical research.

  • Avoid the expensive mistakes and inefficiencies that can arise when individual initiatives repeatedly “re-invent the wheel”, thereby saving funders and researchers a lot of time and money

The Road Map:

  • WG 1: Nomenclature

  • WG 2: Sample handling

  • WG 3: Biobank information

  • WG 4: Phenotype data

  • WG 5: Genotype data

  • WG 6: Data modeling

  • WG 7: Database Integration

  • WG 8: Security

  • WG 9: Output and analysis

  • WG 10: Documentation


P Harmonious Approch3G Knowledge Database

The road map: Phenotype

  • Describe data format naming conventions

  • P3G data format standard (Start with GenomEUtwin documents)

  • Describe relations between the entities

  • Describe entities and their attributes

  • Sync genotype data

  • Questionnaires (validation)

  • Clinical measures

  • Laboratory phenotypes


P Harmonious Approch3G Knowledge Database

The road map: Data modeling

  • Conceptual data modeling using UML (Unified Modeling

    Language)

  • Build conceptual harmonized data model for genotype and phenotype data

  • Sequence variation standardization

  • Provide standardized data transfer format

  • Tracking of samples

  • XML and OWL for future use

The road map: Sampling handling

  • Sample collection

  • Sample identification

  • Data collection

  • Structure and standardization of data

  • Quality control procedures

  • Ethical and legal aspects

  • Name IWG-leaders

  • Name Cores

  • Now, open a KDB members area under www.p3gconsortium.org, to start the knowledge database

  • IWG-KDB meeting late spring 2005

  • Coordinate with other activities
