Advantage Database Server is a relational database management system (RDBMS) for small to medium-sized businesses by SAP SE (formerly Sybase iAnywhere, formerly Extended Systems).
Description [ edit ]
Database author Cary Jensen describes Advantage as follows: "Advantage has been around since 1993, when it was introduced to provide a stable solution for Clipper developers who were tired of slow performance and corrupt indexes inherent to file server-based databases. Over the years, ADS has grown in both popularity and features. Advantage is now a mature product with an impressive collection of features that rival many of the more expensive and complicated database servers".
Advantage Database Server is most popular among application developers as a  client/server backend for shared, networked, standalone, mobile and Internet database applications. ADS provides both ISAM table-based and SQL based data access.
