The Embedded MySQL Server Library provides most of the features of regular MySQL as a linkable library that can be run in the context of a client process. After initialization, clients can use the same C API calls as when talking to a separate MySQL server but with less communication overhead and with no need for a separate database process.
This is a high performance, typesafe numerical array set of classes and functions for general math, FFT and linear algebra. The library, developed for .NET/Mono, aims to provide 32- and 64-bit script-like syntax in C#, 2D & 3D plot controls, and efficient memory management. It is released under GPLv3 or commercial license. [10]
Each thread reading from a database gains ownership of an element in a shared memory array, which it may update to indicate when it is within a transaction. Writers scan the array to determine the oldest database version the transaction must preserve without requiring direct synchronization with active readers.
OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB) is an API designed by Microsoft that allows accessing data from a variety of sources in a uniform manner. The API provides a set of interfaces implemented using the Component Object Model (COM); it is otherwise unrelated to OLE .
Since the processing happens at the database server, local methods, which are not defined as a part of the lambda expressions representing the predicates, cannot be used. However, it can use the stored procedures on the server. Any changes to the result set are tracked and can be submitted back to the database server. [13]
DataFlex is a GUI development language in a style comparable with Visual Basic, Delphi and C++. From version 4 (1996) up until version 17.1 (2015), the product was labeled Visual DataFlex. From version 4 (1996) up until version 17.1 (2015), the product was labeled Visual DataFlex.
A database abstraction layer (DBAL [1] or DAL) is an application programming interface which unifies the communication between a computer application and databases such as SQL Server, IBM Db2, MySQL, PostgreSQL, Oracle or SQLite. Traditionally, all database vendors provide their own interface that is tailored to their products.
Berkeley DB, the C database library that is the subject of this article; Berkeley DB Java Edition, [15] a pure Java library whose design is modelled after the C library but is otherwise unrelated; Berkeley DB XML, [16] a C++ program that supports XQuery, and which includes a legacy version of the C database library
