Perl API Documentation
Ensembl uses MySQL relational databases to store its information. A comprehensive set of Application Programme Interfaces (APIs) serve as a middle-layer between underlying database schemes and more specific application programmes. The APIs aim to encapsulate the database layout by providing efficient high-level access to data tables and isolate applications from data layout changes.
Ensembl's API is written in Perl:
To get a taster of using our API, see the filmed workshop (includes exercises to carry out at your leisure).
Sequence, genes and other automated annotation
Gene trees, homologies, multiple and pairwise genomic alignments
SNPs, somatic mutations and structural variants
Regulatory features, motifs and oligoprobes
The Registry system allows to tell your programs where to find the EnsEMBL databases and how to connect to them. It has been implemented for the Ensembl Core and Compara APIs.
Ensembl Software Support
Ensembl is an open project and we would like to encourage correspondence and discussions on any subject on any aspect of Ensembl. Please see the Ensembl Contacts page for suitable options for getting in touch with us.
If you are interested in undertaking a short-term collaborative project, our "Geek for a Week" scheme allows developers and researchers to work alongside Ensembl team members.
