Spawner can fill up database tables with sample data for testing. It either outputs CSV text values, or generates SQL INSERT statements, according to optionally configured data and field types (numeric, textual, names, address parts, varied-size text / enums / binary data). It can also connect to MySQL 5.x servers for insertions.
FreeTDS is a set of libraries for Unix and Linux that allows your programs to natively talk to Microsoft SQL Server and Sybase databases.
Apache Drill allows to query non-relational datastores. It supports HBase, MongoDB, MapR-DB, HDFS, MapR-FS, Amazon S3, Azure Blob Storage, Google Cloud Storage, Swift, NAS and local files. The aggregation and query mechanism even allows to join across multiple database backends. The query plan optimizer is datastore-aware and utilizes individual NoSQL filter and query mechanisms depending on each backend scheme.
LazSqlX is a cross-platform database management tool. It works with MariaDB/Mysql, PostgreSQL, SQLite, Firebird and Oracle databases.

ERMaster is an Eclipse plugin to make database Entitity-Relationship diagrams. It allows to import from a database, export a table definition to Excel, generate an ER image, or DDL output.
DBeauty is a database browser which visualizes relational structures and table/row interrelations. It can connect to an JDBC-supported SQL database, browser its content, navigate bidirectionally through tables, understands foreign key relations or user-defined connections, can generate SQL/DML, and execute arbitrary SQL queries.
SQL::Yapp is a Perl module which embeds SQL completely and safely into Perl. It checks SQL syntax at compile time and fully parses SQL to allow usage of any Perl scalars, arrays, and hashes in an intuitive and safe way. It makes SQL injections virtually impossible while making you feel as if SQL syntax were native to Perl.
