PostgreSQL is a powerful, relational database system. Is a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness.

EnterpriseDB PostgreSQL free EnterpriseDB
Enterprise PostgreSQL - EnterpriseDB Advanced Server is an enterprise-class relational database management system (RDBMS) that is compatible with applications written for Oracle based on PostgreSQL.

pgAdmin
pgAdmin is the most popular and feature rich administration and development platform for PostgreSQL, running on any platform, as well as commercial and derived versions of PostgreSQL.

phpPgAdmin
phpPgAdmin is a web-based administration tool for PostgreSQL. It is perfect for PostgreSQL DBAs, newbies and hosting services.

One of most popular and important web SQL database, for all type of data. From PC solution to warehouse, full professional and stable.

Adminer is a full-featured database management tool written in PHP. Conversely to phpMyAdmin, it consist of a single file ready to deploy to the target server. Adminer exsists in one edit only version too, and is aviable for MySQL, PostgreSQL, SQLite, MS SQL and Oracle.

VFront VFront (SF)
VFront is a free, open source front-end for MySQL or PostgreSQL databases written in PHP and Javascript. With VFront you can create forms for manage your data in AJAX style, different rules and privileges for groups, report in XML,HTML,PDF,statistics and much more. VFront is released under GPL license (version 2.0). VFront is useful for companies (icl. SOHO) or organizations, which use MySQL or PostgreSQL, in need of an easy consulting or modyfing access to database by their own employed whithout developing a specific client for that but simply using a web browser. VFront as an interface tool for database, similar for some functions to MS access, but taking the lead with an easy access via web. VFront is not a database administration tool like phpMyAdmin and it's not replacing it : interface is for basic user working on data. VFront is created for non-expert users capable to work safely on data using an intuitive graphic interface.

DbVisualizer
DbVisualizer is the universal database tool for developers and database administrators. It is the perfect solution since the same tool can be used on all major operating systems accessing a wide range of databases.

SQL Buddy
Web based MySQL administration - No setup: Just unzip the files to your server and it's ready to use. Seriously, the next step is logging in with complete control of users. Logins are handled directly by MySQL.

nuBuilder

provides an ideal replacement/upgrade from MS-Access. It won't get slower and slower as you add more records; un-like MS-Access. Use MySQL database.

Xataface
is for web developers and database administrators who would like to build a front-end for their MySQL database. However the resulting applications are targeted at non-technical users such as secretaries. Provides extensible and intuitive user interface for MySQL databases with ability to add/edit/delete/search and manage relationships. Written in PHP. (Formerly called Dataface).

DBDesigner
DBDesigner 4 is a visual database design system that integrates database design, modeling, creation and maintenance into a single, seamless environment. Optimized for MySQL.

Open Limbas
Open Limbas is a database management system in order to quickly create web-based applications. Limbas is based on PHP and includes the GPL2 license. Like Access, from basic features such as table management, form and report generator as well as charting and workflow features it can be dynamically modeled with one another to any product solution. The independant database-system includes a pre-integrated User-/Groupmanagement, a document management and various groupware functionalities.

MongoDB (from "humongous", the bigest) is a cross-platform document-oriented database system. Classified as a "NoSQL" database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster.

Apache Cassandra
The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data. Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages. In 2012, University of Toronto researchers studying NoSQL systems concluded that "In terms of scalability, there is a clear winner throughout our experiments. Cassandra achieves the highest throughput for the maximum number of nodes in all experiments" although "this comes at the price of high write and read latencies.

Oracle Database

Oracle Database 12c introduces a new multitenant architecture that makes it easy to consolidate many databases quickly and manage them as a cloud service. Oracle Database 12c also includes in-memory data processing capabilities delivering breakthrough analytical performance. Additional database innovations deliver new levels of efficiency, performance, security, and availability. Oracle Database 12c enables customers to plug into the cloud and power the real-time enterprise. Oracle Database 12c comes in three editions and features a wide range of enterprise edition options to meet specific customer requirements in the areas of performance and availability, security and compliance, data warehousing and analytic, unstructured data, and manageability.
You can download the Oracle database for free. Oracle give: ... license to use the programs only for the purpose of developing, testing, prototyping and demonstrating your application, and not for any other purpose.

Microsoft® SQL Server® 2014 SQL Server Express
Microsoft® SQL Server® Express is one proprietary database, free to develop, deploy, and distribute, they are big starter database for: - Developers working on PHP, Java, .NET, XML, and Open Source applications - DBAs who need a free, starter database for training and deployment - Independent Software Vendors (ISVs) and hardware vendors who want a starter database to distribute free of charge. - Educational and investigation institutions who need a free database for their curriculum, investigation and development. - Limit: 1 processor, 10 GB database.
