BIRDQL

BIRDQL Biological Query Language

BIRDQL in few words

The heterogeneous data integrated in BIRD System are represented by several relational tables. The exploitation of these data by SQL queries is not obvious except for developers or computer scientist experts.

Building queries with SQL in this context is not easy with because that requires to use joins (terme technique) to select data in multiple tables. This complexity must be hidden by HTML forms but a lot of queries can not be setup with HTML forms.

We proposes own query language (BIRDQL), there is new standard biological query language allowing the biologist or clinician to create data retrieval protocols without exhaustive knowledge of the data sources and their architecture. BIRD System is driven with a high level query engine: BIRDQL, which makes it possible for biologists to express easily queries and to extract knowledge by classical constraints and scientific functions (StructuralDistance,SequencePattern,AssociationRule...).

BIRDQL in not a mathematically complete language but indeed an idiom adpated to the GUI, human readable enough to be modified by hand. The construction of this BIRDQL query engine was used some main idea from SaadaQL [1]

BIRDQL Grammar

ID <list of id/ac/query_id > DB <bank names>

WH <Field> Contains <(kw1 & kw2) | kw_n>

WH PATTERN <function SequencePattern() >

WH PATTERN <function DiagonalMolecule()>

WH PATTERN <function InteractionProtein()>

WH PATTERN <function AssociationRule()>

WH SQLNative select from ...

FD <Field out1,Field out2,... / GET_COUNT/GET_DR(bankname)>

OF <OFFSET, Default OF=0>

LM <number of maximum display>

FM <Fasta/Flat/Xml/CSV/Simple/Object/OID>

Two other examples below also show how to use the BIRD-QL syntax.

Example 1: simple query, search and fasta format generation

ID * DB UNIPROT

WH TEXT contains "synthetase" & "tyrosyl" & not ("homo sapiens" & "human")

FD AC, ID,DE,OX,SQ

LM 100

FM FASTA

Example 2: FullText query with operator: & , not (TEXT=definition, organism scientific organism common, dbref,..)

//

ID * DB UNIPROT

WH TEXT contains "histone" & not "homo sapiens"

FD AC,DE,OS

LM 3

FM FLAT

//

ID * DB UNIPROT

WH TEXT contains not "homo sapiens"

FD AC,DE,OS

LM 3

Example 2: complex query, GBFULL=EST+ WGS +Release +New

ID * DB GBFULL
