Records is a Mac utility designed to help you create databases to store information about your book collection, events, customers, expenses, etc. The program gives you access to a wide variety of database templates which can be customized to fit your requirements.
Unlike other database creating tools for Mac, this utility comes with a reasonable price. It also features an efficient search tool, enables you to print your database info directly from its interface, and lets you choose between various database view and sort options.
Personally, I had some difficulties learning how the program works. To be more exact, it took me a while to find a way to include elements into my database (fields like contact names, dates, etc.). So, an integrated help manual wouldn't hurt, especially to beginner Mac users.
Furthermore, the program supports a few output formats when it comes to exporting the stored content.
In conclusion, it's up to you to decide, based on your needs and if the aforementioned aspects bother you or not, if it's worth buying this product for your Mac.
