What methods allow non-technical users to retrieve database information?

Non-technical users can retrieve database information through query builders, report generators, and data visualisation tools.

Query builders are user-friendly tools that allow non-technical users to retrieve data from a database without needing to know SQL or any other database language. They provide a graphical interface where users can select the data they want to retrieve, and the tool generates the necessary SQL code in the background. This makes it possible for users to retrieve data without having to understand the underlying database structure or syntax. Examples of query builders include Microsoft Access and Oracle's SQL Developer.

Report generators are another method that non-technical users can use to retrieve database information. These tools allow users to create customised reports based on the data in a database. Users can select the data they want to include in the report, and the tool will retrieve the data and format it in a readable way. This can be particularly useful for business users who need to analyse data for decision-making purposes. Examples of report generators include Crystal Reports and Microsoft's SQL Server Reporting Services.

Data visualisation tools are a third method that non-technical users can use to retrieve database information. These tools allow users to create visual representations of data, such as graphs and charts, which can make it easier to understand and interpret the data. Users can select the data they want to visualise, and the tool will retrieve the data and create the visualisation. This can be particularly useful for users who need to present data to others in a clear and understandable way. Examples of data visualisation tools include Tableau and Microsoft's Power BI.

In conclusion, while databases can be complex and difficult to understand, there are a number of tools available that make it possible for non-technical users to retrieve database information. These tools abstract away the complexity of the database, allowing users to focus on the data itself.
