# Introduction

The ChEMBL Data Deposition Guide aims to assist depositors in correctly formatting data for submission to ChEMBL.

Developed by the European Molecular Biology Laboratory's European Bioinformatics Institute, ChEMBL is a manually curated database of bioactive molecules with drug-like properties. It brings together chemical, bioactivity and genomic data to aid the translation of genomic information into effective new drugs.  

ChEMBL is a [relational database](https://en.wikipedia.org/wiki/Relational_database); data is stored in tables which are linked by unique identifiers (primary and foreign keys, as discussed in the linked article).  The [ChEMBL schema](https://www.ebi.ac.uk/chembl/db_schema) can be accessed for more information about the structure of the public database.
