Comparison Result
Colored background highlighting and font bolding is used to indicate differences in comparison results. Aqua Data Studio highlights the comparison between the schemas, tabs, files, directories, clipboard history, and results in different colors. Differences are highlighted in the default pink (deleted), purple (changed), or green (added). You can assign new colors from the Options dialog.
Version Control
Compare tools are also thoroughly integrated within Aqua Data Studio. When a version-controlled file is modified, Aqua Data Studio displays inline diff indicators on the Annotation bar. The inline diff indicator allows live comparisons with the local source control repository to be run as editing continues. A green diff indicator () signifies addition and a blue diff bar indicator (
) signifies replacement. An arrow
signifies the deletion of lines.
Files viewed within the Repository Browser can also be compared with their previous versions. 
Comparison Filters
Aqua Data Studio provides various comparison filters and options. When files, queries, or tabs are compared, the comparison functions down to the character level within each. When schemas are compared, the level of comparison granularity can be set by the user for database schema object types as desired. For even more control over the comparison, you can apply filters to the comparison result. The results of all comparisons can be saved as HTML for storage or sharing.
