Hi, I am not a programmer or software developer or very computer savvy. So I would very much appreciate some help - I would like to know what is a relational database back-end? I can't find the definition on the Internet. Also, can I use it in a sentence like this: "Since CPAS is based on a relational database back-end, it collects, stores and analyses data from proteomics experiments."??

Whoohoo! Nevermind I got it - just googled the terms separately. A relational database is a collection of data items organized as a set of formally described tables from which data can be accessed easily. A relational database is created using the relational model. The software used in a relational database is called a relational database management system (RDBMS). A relational database is the predominant choice in storing data, over other models like the hierarchical database model or the network model. It consists of n number tables and each table has its own primary key. A back-end database is a database that is accessed by users indirectly through an external application rather than by application programming stored within the database itself or by low level manipulation of the data (e.g. through SQL commands). A back-end database stores data but does not include end-user application elements such as stored queries, forms, macros or reports.
