Some funders now make data sharing a requirement (you can check RDO funder requirements page), and it’s become increasingly commonplace for some subject areas to make data available to everyone.
The basic data sharing policy encourages authors to deposit data in a suitable repository, cite it, and include a data availability statement, sometimes referred to as a ‘data access statement’, which is crucial in signposting where the data associated with a paper is available, and under what conditions the data can be accessed, including links (where applicable) to the data set.
Some publishers offer Data availability statement templates, see Taylor and Francis, Elsevier, Springer Nature, others just give general advice on data availability, see PLOS Genetics.
Data citation is rapidly emerging as a key practice supporting data preservation, access and reuse, as well as sound scholarship.
Data Citation Synthesis Group (FORCE11), a cross-team committee, published a set of data citation principles*, which represents practices used in the research and publishing arenas and in common use.

An exhaustive guide, How to Cite Datasets and Link to Publications from the Digital Curation Centre (DCC) discusses data citation in great detail, with information for researchers and data repositories.
ORA-data, part of Oxford Research Archive designed to help access, create, archive, share and cite research data, advises researchers to follow these guidelines.
Sometimes the website has this information on individual data set pages. More frequently, the website or database where you found your data will also have information on how to cite that data in their FAQs, "About" page, or "How to Use" information
The APA Style Guide provides a recommended citation format for databases, with examples, but other style guides, including MLA and Chicago, don't--so you'll have to create your own.
You can try using CrossCite Citation Generator, which generates citations in many styles, and all you need to provide is the DOI from a dataset.
For citation styles that do not have a specific dataset format, you can base your citation on the closest equivalent formats: if the dataset is online, use a format for online items, and if it was created by multiple "authors" or editors or researchers, use a format for edited works or items with more than one author. Or, just base your citation off of the general reference format for your style guide.
If a grant application, scholarly journal, or instructor has strict requirements for citations, they'll usually make this clear, and may provide examples. If they don't offer an example for citing the kind of dataset you are using, don't be afraid to ask.
Use the reference type for "dataset".
Use other more generic reference type templates and fill in the essentials for your dataset.
Enter the citation in the system as a "Document," depending upon if/how the data producer provides a recommended citation; either:
• Export an RIS file and import this file into Zotero;
• Copy and paste the information from a recommended citation into a new Zotero item with the type "Document";
• Otherwise, use the "Document" item type to add the components of the citation.
The rise of electronic journals has led to new services being added to simple article access. One of these is the provision of forward links to papers citing the one being accessed.
An example of research dataset linking can be found on the Scopus page. If research datasets are available on the external data repository for an article, the Scopus Document details page will include a “Related Research Data” sidebar, located to the right of the article details. To access the dataset, click on the links provided.
Additional advice on general obligations of using or sharing data and more specifically on citation of data may be found on the Research Data Oxford website.
