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]. SaadaQL query language was developed in my PhD ( Astrophysics & Virtual Observatory ,2002-2006).

BIRDQL Grammar

WH <Field> Contains <(kw1 & kw2) | kw_n>
WH PATTERN <function SequencePattern() >
WH PATTERN <function DiagonalMolecule()>
WH PATTERN <function InteractionProtein()>

BIRDQL example
Data can be selected with BIRD Data Access Protocol
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
Result
>Q92PK5 | SYY_RHIME | Tyrosyl-tRNA synthetase (EC 6.1.1.1) (Tyrosine--tRNA ligase) (TyrRS). | 382

Example 2: FullText query with operator: & , not (TEXT=definition, organism scientific organism common, dbref,..)
ID * DB REFSEQ
WH TEXT Contains "Tyrosyl-tRNA synthetase" & "Homo sapiens"
LM 100
FM FASTA
//
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
WH OC Contains "Eukaryote"
WH DR Contains "GO"
WH GENE contains "GF100027"

The query above allow to search in Genbank full, the Eucaryotic sequences containing the GF100027 gene with a cross reference in GeneOntology.
Example 3: mining in GENBANK EST
