Memento Database is a database management software tool for mobile devices (Android) and personal computers (Microsoft Windows, Linux, Apple Macintosh). Elements of a user's database — [[Library|libraries]] and associated files — may be synchronized across these [[Platforms|platforms]] via an available cloud service. Libraries also may be [[Sync with Google Sheets|synchronized with Google Sheets spreadsheets stored on the user's Google Drive]] to enable the user's data to be manipulated or analyzed by either tool, as needed. [[Importing and exporting CSV files|Import/export from/to comma-delimited (CSV) files]] enables coordinated use with external applications, like Microsoft Excel.

Data libraries may be linked, allowing any number of libraries to work together to form a database and provide a solution.

All data can be stored in the [[Cloud storage and Teamwork|Memento Cloud]]. All such libraries, photos, and files are synchronized automatically between the cloud and local copies on Android devices. Users can provide access to their data to other users, enabling [[Cloud storage and Teamwork|teamwork use]].

Memento's online catalog of user templates contains thousands of predefined, ready-to-use libraries to use directly or serve as a starting place. It also gives users the opportunity to familiarize themselves with a large number of ways to use Memento to provide solutions.

=== [[Platforms]] ===
=== '''''[[Platforms]]''''' ===
Memento was first implemented on the Android platform for smartphones and tablets, and Android continues to be a prime platform for Memento. The Mobile Edition operates off locally stored data that may or may not be synchronized to the Memento Cloud.

=== Primary data structures ===
=== Primary data structures ===
User data is stored in Memento in Fields within a Library. See [[Terminology]] to see how this relates to other database technologies and tools. A collection of libraries is called a Group. A collection of fields within a Library structure is called a Page. When data is entered into fields, an Entry is created, so while a library's structure is made up of fields, the library itself is made up of entries.
