Lincoln C.

Systems Engineer

“Liked comparing files within a single window and exporting the differences to CSV for follow-up. Found that the free version includes less than thirty percent of the available tools.”

reshma P.

BI Analyst

“Liked running scripts against two databases at the same time, which saves time on comparisons. Found the layout and color scheme dull and dated compared with newer tools.”

Daniel V.

Senior Software Engineer

“Liked fast processing and low memory use with large data, plus a progress display. Found a dated interface, missing export and match views, and freezing during extraction.”

Pierre E.

Actuary

“Liked writing custom queries and how easily columns can be excluded from comparisons. Found that the user interface is not particularly attractive to look at or work in.”

Integrations

JuxtAPPose integrations

JuxtAPPose connects directly to relational databases and files rather than to business applications. It can extract data from Microsoft SQL Server, MySQL, Amazon Aurora and Oracle, and it can also read flat files, so teams can compare a database table against an exported file or two databases against each other. Users can write custom queries to limit comparisons to specific subsets, exclude columns that should be ignored, and save comparison results for later review. Some versions allow differences to be exported to CSV for follow-up in spreadsheets or ticketing tools. The application installs on Windows desktops and runs comparisons locally.
