    <p>I think the reason of why text files are used in development is that they are universal against various development tools. You can look inside or even fix some errors using a simple text editor (you can't do it in a binary file because you never know how any fix would destroy other data). It doesn't mean, however, that text files are best for all those purposes.</p> <p>Of course, you can diff and merge them. But it doesn't mean that the diff/merge tool understand the distinct structure of the data encoded by this text file. You can do the diff/merge, but (especially seen in XML files) the diff tool won't show you the differences correctly, that is, it will show you where the files differ and which parts of the data the tool "thinks" are the same. But it will not show you the differences in the structure of XML file - it will just match lines that look the same.</p> <p>Regardless whether we're using binary files or text files, it's always better that the diff/merge tools take care of the data structure this file represents rather than the lines and characters. For C++ or Java files, for example, report that some identifier changed its name, report that some section was surrounded with additional if(){}, but, on the other hand, ignore changes in indents or EOL characters. The best approach would be that a file is read into internal structures and dumped using specific format rules. This way the diff-ing will be made through the internal structures and the merge result will be generated from the merged internal structure.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
