Informational Elements



Users need essential information to decide if the database suits their needs.


Critical information needs to be available in the user interface to support the use of the database. The basic information includes how to interpret the tool’s prediction score, if the database is updated and how to cite the database.


The Informational Elements are usually contained on or accessed from the tool’s main page. They do not necessarily compose a single information block in the interface but present related information whose primary purpose is to inform the user about the use and status of the tool. The main page should display the current information about the number of miRNA targets supported and the last update date (Status and Statistics). The main page is also the preferred place to display the Citation that users must use to reference the database. The Informational Elements must also comprise the Methods used to calculate the prediction score shown in the Data Presentation. A Contact information should also be displayed to enable users to reach out for questions and suggestions.


Informational Elements should help the user quickly decide on using the database. A common problem with databases of miRNAs targets is a lack of updates (Mullany et al., 2015), so the user needs to quickly identify the Status and Statistics of the tool. Citation is essential so that the user correctly references what database was used to produce the results in their paper. Low interpretability of the results is one problem that affects users (Mullany et al., 2015). Thus, it is important that users can easily consult the Methods used for target prediction. Additionally, Contact can enable users to keep the database Status and Statistics up to date by submitting suggestions or updates.





  • The main page display information about the Methods used to predict miRNA targets.
  • Citation is easily visible on the bottom of the main page.
