Ferret: Ferret is the GNU data modeller. It lets you create data models and implement them in a relational database. You can draw your data model via an entity-relation diagram, generate the tables from it (another graphical diagram), and then generate the SQL that creates such relational tables. Several SQL dialects are supported (for most popular free software database systems) and it is very easy to patch the sources to support more. This package was formerly known as 'GerWin.'

FerretDB: Modified from README.md: FerretDB was founded to become the de-facto free software substitute to MongoDB. FerretDB is an free software proxy, converting the MongoDB 6.0+ wire protocol queries to SQL - using PostgreSQL or SQLite as a database engine. FerretDB is compatible with MongoDB drivers and popular MongoDB tools. It functions as a drop-in replacement for MongoDB 6.0+ in many cases. Features are constantly being added to further increase compatibility and performance.

Ffproxy: ffproxy is a filtering HTTP proxy server that can filter by host, URL, and/or header. Custom header entries can be filtered and added. It can even drop its privileges and optionally chroot() to a directory. It supports logging to syslog() and using another auxiliary proxy server.

Glom: 'Glom' is a GUI that lets you design PostgreSQL table definitions and the relationships between them, as well as edit and search the data in those tables. The design has the added advantage of separation between interface and data. It attempts to provide a simple generic framework sufficient to implement most database applications (which normally consists of lots of repetitive, unmaintainable code). Glom-specific data such as the relationship definitions is saved in the Glom document. Glom re-connects to the postgreSQL server when it loads a previous Glom document. The document is in XML format.

Gnome transcript: GNOME Transcript is an SQL database client with a plugin system that supports multiple database servers. It features different table designers for different database servers (based on the plugin system) to maximize the capabilities of each server, the ability to drop/browse/edit tables easily, and the ability to open multiple connections at the same time. You can also work with multiple connections from different servers at the same time.

Gnowsys: GNOWSYS is an acronym for "Gnowledge Networking and Organizing SYStem." It is a web based object oriented database server with each object provided by an unique URL. GNOWSYS is a tool to construct and store persistently a Gnowledge Base (GB). The GB consists of the following three groups of constructor classes (system and temporal classes under development): PredicateGroup: relationType, relation, functionType, function Object Group: metaType, class, object (with provision to have classes and objects of declarative, procedural, encapsulated, temporal etc.) Structure Group: systemType, system, flowType, flow, processType, process GNOWSYS indexes data and metadata of objects in a catalogue for faster queries. Optionally, data can remain anywhere on the Internet (only the metadata stays in the database). Surrogates of procedures (classes, functions, and system calls) can also be installed in the database as special objects. These procedures execute as web services, so users can design applications without writing program in any programming language by specifying the semantics of a program and mapping the elements of the program to the surrogates of procedures is sufficient for GNOWSYS to test the application design.

Gnu Hosting Helper: This package provides tools to manage many of the aspects of a hosting environment.It also provides a client utility to reduce the need for staff to perform tasks that a client needs such as managing email accounts.

HTTP-Replicator: 'Replicator' is a replicating HTTP proxy server. Files that are downloaded through the proxy are transparently stored in a private cache, so an exact copy of accessed remote files is created on the local machine. It is, in essence, a general purpose proxy server, but especially suited for maintaining a cache of Debian or Gentoo packages.

Halberd: To cope with heavy traffic loads, web site administrators often install load balancer devices. These machines hide (possibly) many real web servers behind a virtual IP. They receive HTTP requests and redirect them to the real web servers in order to share the traffic between them. Halberd is a tool aimed at discovering real servers behind virtual IPs.

Haskell Database Connectivity: HDBC provides an abstraction layer between Haskell programs and SQL relational databases. This lets you write database code once, in Haskell, and have it work with any number of backend SQL databases (MySQL, Oracle, PostgreSQL, ODBC-compliant databases, etc.)

Say you have a program that records your steps, one that monitors work outs, and a third program to track your nutrient intake. Typically, if you wanted to access your information, you'd have to use each respective service's interface. With HealthBox, those developers would be able to store all the information in one place, making it much easier for you to compare different health metrics, and share information between services.

Hipercontracer: High-Performance Connectivity Tracer (HiPerConTracer) is a ping/traceroute service. It performs regular ping and traceroute runs among sites and can export the results into an SQL or Non-SQL database.

Two SMTP back-ends are provided. One delivers mail to qmail-queue, mimicking most of the behavior of qmail-smtpd, with the addition of support for SMTP AUTH. The other rejects all SMTP commands if $SMTPREJECT is set, and execs its command line otherwise (in order to run the above program).

Mandos: The Mandos system allows computers to have encrypted root file systems and at the same time be capable of remote and/or unattended reboots. WouldnÃ¢â¬â¢t it be great if you could have the security of encrypted root file systems and still have servers that could boot up automatically if there was a short power outage while you were asleep? That you could reboot at will, without having someone run over to the server to type in the password? Well, with Mandos, you (almost) can! The gain in convenience will only be offset by a small loss in security. The setup is as follows: The server will still have its encrypted root file system. The password to this file system will be stored on another computer (henceforth known as the Mandos server) on the same local network. The password will *not* be stored in plaintext, but encrypted with OpenPGP. To decrypt this password, a key is needed. This key (the Mandos client key) will not be stored there, but back on the original server (henceforth known as the Mandos client) in the initial RAM disk image. Oh, and all network Mandos client/server communications will be encrypted, using TLS (SSL).

MaraDNS: 'MaraDNS' is a fully functional DNS server supporting authoritative DNS, recursive DNS, and caching DNS. It is intended for environments where a DNS server must be secure and where the server must use the absolute minimum number of resources possible.

MonetDB: MonetDB is a database management system developed from a main-memory perspective using a fully decomposed storage model, automatic index management, extensibility of data types and search accelerators, and SQL- and XML- frontends. It was designed to provide high performance on complex queries against large databases, e.g. combining tables with hundreds of columns and multi-million rows. Because of this, MonetDB can be used in application areas that have in the past been too slow for using traditional database technology in real-time.

Mongo Engine: MongoEngine is a Python Object-Document Mapper for working with MongoDB. Documentation available at http://hmarr.com/mongoengine/ - there is currently a tutorial, a user guide and an API reference.

MongoDB

In Oct 2018, MongoDB's "community edition" switched from AGPLv3 to another license making it harder for free software users to depend on it. The source linked in this entry is the last available code base under the AGPLv3. See FerretDB for an alternative. MongoDB (from "humongous") is a scalable, high-performance, schema-free, document-oriented database. Features:

Document-oriented storage (the simplicity and power of JSON-like data schemas)
Dynamic queries
Full index support, extending to inner-objects and embedded arrays
Query profiling
Fast, in-place updates
Efficient storage of binary data large objects (e.g. photos and videos)
Replication and fail-over support
Auto-sharding for cloud-level scalability
MapReduce for complex aggregation

Monkey HHTP Daemon: Monkey HTTP Daemon is a small, fast Web server. It is based on the HTTP 1.1 protocol. Features include language support, GET, POST, and HEAD methods, CGI, PHP4, a config file (optional for every user), a mime.types file, virtual hosts, the ability to deny URLs and IPs, to run as a different user (such as nobody), serve users home directories, and more.

Mumblr: Mumblr is a simple Tumblelog application, written in Django. It uses MongoDB as its database, and MongoEngine for communicating with MongoDB from Django.

My SQL Navigator: MySQL Navigator is MySQL database server GUI client program. The purpose of MySQL Navigator is to provide a useful client interface to MySQL database servers, while supporting multiple operating systems and languages. You can currently enter queries, get result sets, edit scripts, run scripts, add, alter, and delete users, and retrieve client and server infomation.

My2pg: 'my2pg' converts MySQL 3.22 and 3.23 dumps into Postgres dumps. It emulates ENUMs and SETs via user types and operators. It is intended for PostgreSQL users who want to migrate from MySQL. It is included in the contributed tree of the PostgreSQL distribution.

MyBkp 2: This is a candidate for deletion: 1. No files sources found. This is a Korn shell script for performing various backup and recovery related tasks of MySQL. This tool can be used for various purposes including various kinds of backups (Dump, Cold, Hot, Snapshot), restoration of backups in a database, verifying the backups (checksum), set Retention policy for backups, generating reports of backups taken and their status, scheduling Jobs for backups and report generation, and doing Point-in-time recovery.

MyClient: MyClient is a Web client interface for the MySQL database. Features include multiple query windows, one-button table descriptions, one button database switching, query save and load, and query results saving. It is not a full featured administration tool, but a quick and easy query interface for users who want a Web-based implementation of the command line interface.

MyDNS: MyDNS is a free DNS server for *nix. It was implemented from scratch and is designed to serve records directly from an SQL database (currently either MySQL or PostgreSQL). Its primary objectives are stability, security, interoperability, and speed, though not necessarily in that order. MyDNS does not include recursive name service, nor a resolver library. It is primarily designed for organizations with many zones and/or resource records who desire the ability to perform real-time dynamic updates on their DNS data via MySQL.

MySQL: MySQL is a fast, reliable, and easy to use relational database management system that supports the standardized Structured Query Language.

MySQL Backup: MySQL Backup is a Perl script that uses mysqlshow to grab the database names and "show tables" to grab the table names for a user's account, and then uses mysqldump to save the data in a subdirectory named in the script. It then tars and gzips the files, using the date and time for the file name. It can be run from cron on a daily basis. It removes old files and has an option to email the gzip file to an admin and/or FTP the backup file to a remote server. It also has options to use "select data into outfile" or a regular "select" for users who can't use mysqldump. It supports LARGE sets of databases and tables (GNU/Linux utilities such as tar, ls and nice break when the argument list gets too long). To do this, the script places all the sql text files in a subdirectory and tars the directory. For security, if a .my.cnf file is used then mysqlshow and mysqldump run without the --user and --password parameters, so the password doesn't display in the process list.
