# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://chembl.gitbook.io/chembl-data-deposition-guide/master.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
