* Sailboats database: sailing yacht data sheets all over the world

Development of this type of database involved not only design issues but the development of complex interfaces whereby researchers could access existing data as well as submit new or revised data.

Berkeley DB ( BDB ) is a software library that provides a high-performance embedded database for key / value data.

A program accessing the database is free to decide how the data is to be stored in a record.

* MySQL database system – Prior to v5. 1, MySQL included a BDB data storage backend.

The database does not reveal the actual passwords or keylogged data.

The company planned to monetize their work by creating a value-added database of genomic data to which users could subscribe for a fee.

In computing, a data warehouse ( DW or DWH ) is a database used for reporting and data analysis.

The staging layer or staging database stores raw data extracted from each of the disparate source data systems.

The integration layer integrates the disparate data sets by transforming the data from the staging layer often storing this transformed data in an operational data store ( ODS ) database.

The integrated data are then moved to yet another database, often called the data warehouse database, where the data is arranged into hierarchal groups often called dimensions and into facts and aggregate facts.

Data federation methods or data virtualization methods may be used to access the distributed integrated source data systems to consolidate and aggregate data directly into the data warehouse database tables.

While it is true that a workbook that contains three sheets is indeed a file containing multiple tables that can interact with each other, it lacks the relational structure of a database.

Additionally, it has other features such as web album export, annotations, database and keyword searching, contact sheets, screen shows, batch conversion, photo finishing, red eye correction, screen capture and TWAIN import.

Facts sheets, reports, expenses, charter, and other information is included in the database.

* Lamarck's Herbarium ( online database with 20. 000 sheets in HD )

There is also a " Highlights " database with longer entries on over 4, 000 objects, and several specialized online research catalogues and online journals ( all free to access ).

Fully normalized database designs ( that is, those satisfying all five Codd rules ) often result in information from a business transaction being stored in dozens to hundreds of tables.

The database research area has several notable dedicated academic journals ( e. g., ACM Transactions on Database Systems-TODS, Data and Knowledge Engineering-DKE, and more ) and annual conferences ( e. g., ACM SIGMOD, ACM PODS, VLDB, IEEE ICDE, and more ), as well as an active and quite heterogeneous ( subject-wise ) research community all over the world.

More and more such database products are emerging, both of new vendors and by virtually all established database vendors.

The database needs to be based on a data model that is sufficiently rich to describe in the database all the needed respective application's aspects.

It balances all the external views ' performance requirements, possibly conflicting, in attempt to optimize the overall database usage by all its end-uses according to the database goals and priorities.

Database security deals with all various aspects of protecting the database content, its owners, and its users.

First, the conceptual level is designed, which defines the over-all picture / view of the database, and reflects all the real-world elements ( entities ) the database intends to model, as well as the relationships among them.

When the database is ready ( all its data structures and other needed components are defined ) it is typically populated with initial application's data ( database initialization, which is typically a distinct project ; in many cases using specialized DBMS interfaces that support bulk insertion ) before making it operational.

The transformation should maintain ( if possible ) the database related application ( i. e., all related application programs ) intact.

* DBMS management and operation component-Comprises many components that deal with all the DBMS management and operational aspects like performance monitoring and tuning, backup and restore, recovery from failure, security management and monitoring, database storage allocation and database storage layout monitoring, etc.

Practically only a very small percentage of addresses is kept as initial reference points ( which also requires storage ), and most of the database data is accessed by indirection using displacement calculations ( distance in bits from the reference points ) and data structures which define access paths ( using pointers ) to all needed data in effective manner, optimized for the needed data access operations.

In other words, to the outside world a committed transaction appears ( by its effects on the database ) to be indivisible, atomic, and an aborted transaction does not leave effects on the database at all, as if never existed.

Thus since a database can be normally changed only by transactions, all the database's states are consistent.

In the navigational approach all of these data would be placed in a single record, and unused items would simply not be placed in the database.

The searchable photo database permits browsing and retrieval of over 550 historical images.

A database is not generally portable across different DBMS, but different DBMSs can inter-operate to some degree by using standards like SQL and ODBC together to support a single application built over more than one database.

In general it typically refers to a modular DBMS architecture that allows distinct DBMS instances to cooperate as a single DBMS over processes, computers, and sites, while managing a single database distributed itself over multiple computers, and different sites.

The information may comprise specific database objects ( e. g., record types, specific records, data structures ), certain computations over certain objects ( e. g., query types, or specific queries ), or utilizing specific access paths to the former ( e. g., using specific indexes or other data structures to access information ).

A database transaction is a unit of work, typically encapsulating a number of operations over a database ( e. g., reading a database object, writing, acquiring lock, etc.

IBM ’ s IMS system and the RDM Mobile are examples of a hierarchical database system with multiple hierarchies over the same data.

A database transaction is a unit of work, typically encapsulating a number of operations over a database ( e. g., reading a database object, writing, acquiring lock, etc.

A relational normalised database imposes a heavy access load over physical storage of data even if it is well tuned for high performance.

The FAO Statistical Division produces FAOSTAT, an on-line multilingual database currently containing over 3 million time-series records from over 210 countries and territories covering statistics on agriculture, nutrition, fisheries, forestry, food aid, land use and population.

* Luding. org-board game database with over 15, 000 English and German reviewed games

This database covers 11 major data series for over 200 countries.

* A database containing factorizations, complete and incomplete, of over 500 million numbers.

This was a significant advance over MFT's memory management, but had some weaknesses: if a job allocated memory dynamically ( as most sort programs and database management systems do ), the programmers had to estimate the job's maximum memory requirement and pre-define it for MVT.

The majority of the efforts have looked at embedding spatial database indices such as the Space Filling Curves ( SFCs ) including the Hilbert curves, Z-curves, k-d tree, MX-CIF Quad tree and R *- tree for managing, routing, and indexing of complex Grid resource query objects over DHT networks.

The computer system and database used for this service were not sold, taken over, or continued in any way.
