	Embedded Database - Daffodil DB
		Embedded Database: Daffodil DB Daffodil DB Embedded Database edition is a platform-independent, feature-rich and zero-administration Java RDBMS that complies with SQL 99, JDBC 3.0 and J2EE standards.
		Daffodil DB embedded database supports multiple-concurrent connections and has been designed specifically for embedding inside Java applications.
		Daffodil DB Embedded Database edition has the advantage of being practically invisible to the user, since it requires no administration and runs in the same Java virtual machine (JVM) as the application.

	Embedded Databases
		Embedded databases are sometimes referred to as "fire and forget" or "implement and forget" databases, since they require no or minimal database administration.
		The embedded database, once a backwater of the database market, is starting to become an important player in the industry as leading database vendors are competing to introduce embedded editions of their RDBMS's.
		What drives the actual choice of a particular embedded database is the purpose of the application/solution/device, available processing speed and memory, the capabilities of the embedded database, migration requirements, and software design considerations such as language and SQL support.

	Embedded.com - Embedded database adds RTOS support
		SANTA CRUZ, Calif. — Promising to bring enhanced search capabilities to embedded software developers, Hitachi 's Embedded Business Group is announcing that Entier, its relational database management system, is being ported to real-time operating systems (RTOSes) from Mentor Graphics Corp. and Wind River Systems.
		Hitachi claims that a minimum-size relational database with SQL search capability will take as little as 300 kbytes.
		Steven King, vice president of marketing at Hitachi's Embedded Business Group, said Hitachi has already ported Entier to Mentor Graphics' Nucleus Plus RTOS, and is in the process of porting Entier to Wind River's Linux Edition and VxWorks Edition operating systems.

	Berkeley DB: DB->stat (Site not responding. Last check: 2007-10-21)
		This ensures the stability of the data items read during the stat operation but permits that data to be modified or deleted by other transactions prior to the commit of the specified transaction.
		Database items read during this operation may include modified but not yet committed data.
		If the database was not opened read-only and the DB_FAST_STAT flag was not specified, the cached key and record numbers will be updated after the statistical information has been gathered.

		Embedded databases are particularly prevalent in accounting software, retail applications such as West Marine's, and applications for the health-care industry.
		Despite their obvious benefit and almost ubiquitous nature, sales of database software for embedded applications have slumped badly during the recession--people aren't buying as many refrigerators, vending machines, industrial controllers, networking devices, airplanes, and medical-imaging systems, and so they're not buying as many embedded databases.
		What's more, large packaged applications with embedded databases seem to be losing some of their popularity, while vertical-market and workgroup applications with embedded databases are becoming more prevalent, Aberdeen Group analyst Wayne Kernochan says.

		Database configuration and maintenance have historically been complex tasks, often requiring expert knowledge of database design and application behavior.
		In an embedded environment, it is not feasible to require such expertise and ongoing database maintenance.
		By "embedded" I mean a database that does not run in a separate process, but instead is directly linked ("embedded") into the application requiring access to the stored data.

	Sleepycat Software: Products: Technical Features of Berkeley DB (Site not responding. Last check: 2007-10-21)
		Moving databases from one location to another, or even from one machine to another, is simpler, since it only requires copying ordinary files.
		For example, one database may store information on employees by employee ID, and another may store information on departments by department ID. If each employee is assigned a department ID, then Berkeley DB can join the two databases, and fetch department-specific information via the employee database.
		After a failure, a database can be restored to its last transaction-consistent state by restoring the database file and rolling the log forward.

	SQLite CVSTrac
		Db.* is designed to be embedded in a C/C++ application and access data using a library of C function calls.
		However, based on the file formats one would expect a db.* database to use less disk space when all records are nearly the same size (contain strings with the same number of characters and numeric values of the same magnitude.) When records are of varying size, SQLite database files are expected to be smaller.
		The database uses a fixed schema that must be defined before the application is compiled.

	The Dxstore Database System
		As part of this project, a database of free database systems is being compiled.
		database looks like any another file on the system, so the usual commands can be used to control access to the database, rename or copy it, and so on.
		In some databases, the size of a stored value must be known at the time the data is given to the database and the data must all reside in contiguous memory.

	Berkeley DB: DB->rename (Site not responding. Last check: 2007-10-21)
		If no database is specified, the underlying file represented by file is renamed, incidentally renaming all of the databases it contained.
		On these architectures, attempts to rename databases that are currently in use by any thread of control in the system may fail.
		The database parameter is the database to be renamed.

	Berkeley DB: Db.upgrade (Site not responding. Last check: 2007-10-21)
		Unlike all other database operations, Db.upgrade may only be done on a system with the same byte-order as the database.
		Further, because the Db.upgrade method upgrades a physical file (including all the databases it contains), it is not possible to use Db.upgrade to upgrade files in which some of the databases it includes have sorted duplicate data items, and some of the databases it includes have unsorted duplicate data items.
		If the file does not have more than a single database, if the databases do not support duplicate data items, or if all of the databases that support duplicate data items support the same style of duplicates (either sorted or unsorted), Db.upgrade will work correctly as long as the Db.DB_DUPSORT flag is correctly specified.

	Why Use an Embedded Database? (Site not responding. Last check: 2007-10-21)
		Relational databases running on standalone servers are such a fundamental part of the way we view data today, that it can be hard to recognize occasions in which other relational database models are more effective.
		Later, if this embedded database has to sync with another (such as Outlook synching with Microsoft Exchange or with a handheld device), you rely on application-level data import and export functions to perform this function.
		The best embedded databases have several traits in common: they don't consume a lot of resources, they're fast, and they are utterly reliable—three qualities that consumer products must deliver in today's highly competitive markets.

		The DB handle is the handle for a Berkeley DB database, which may or may not be part of a database environment.
		The handle should not be closed while any other handle that refers to the database is in use; for example, database handles must not be closed while cursor handles into the database remain open, or transactions that include operations on the database have not yet been committed or aborted.
		The database will be opened in the environment specified by the OPENINFO parameter of the GROUPS section of the ubbconfig file.

	DotNetFirebird: Using Firebird SQL in .NET: January 2005
		Of those surveyed, 23 percent of developers picked Firebird for use in "edge" databases—in other words, those that are embedded in systems or in devices, such as a point-of-sale system in a retail outlet or a network device.
		To summarize: Embedded Firebird is a clear win when you need a fully embedded database that users are not aware of.
		One of the cool Firebird features is that the database can be deployed just by copying the database file (although you can have a database in multiple files, by default it is in a single one).

	Berkeley DB: DB_ENV->set_lk_detect (Site not responding. Last check: 2007-10-21)
		As transactions acquire locks on behalf of a single locker ID, rejecting a lock request associated with a transaction normally requires the transaction be aborted.
		Although the DB_ENV->set_lk_detect method may be called at any time during the life of the application, it should normally be called before making calls to the db_env_create or db_create methods.
		Use whatever lock policy was specified when the database environment was created.
