You want to publish an article but you don't know the answer? How much experience do you have with them (I've never heard of them). How easy was it for you to install them, connect them to a website, find libraries to query them etc?
Do you want to use the content of these databases for your article, or do you want the information about your article to appear in these databases? If the first case, then you should read their conditions, and (may be) pay for the access. If the second case, then, if your article will be published in the respected place, then these databases will harvest the information about your article by themselves. These databases harvest the information about the citations in the scientific articles, similar to the links on the web, and these databases calculate the citation weights of the articles, similar to PageRank, Page Authority, and so on.
