A JDBC-ODBC bridge consists of a JDBC driver which employs an ODBC driver to connect to a target database. This driver translates JDBC method calls into ODBC function calls. Programmers usually use such a bridge when a given database lacks a JDBC driver, but is accessible through an ODBC driver.
The JDBC driver gives out the connection to the database and implements the protocol for transferring the query and result between client and database. JDBC technology drivers fit into one of four categories. [2] JDBC-ODBC bridge; Native-API driver; Network-Protocol driver (Middleware driver) Database-Protocol driver (Pure Java driver) or thin ...
Type 1 that calls native code of the locally available ODBC driver. (Note: In JDBC 4.2, JDBC-ODBC bridge has been removed [15]) Type 2 that calls database vendor native library on a client side. This code then talks to database over the network. Type 3, the pure-java driver that talks with the server-side middleware that then talks to the database.
GaussDB supports application development in languages such as C and Java, and provides interfaces for JDBC and ODBC. [4] An advanced generation of GaussDB was launched in June 2023. [5] GaussDB provides an array of capabilities for database management.
The unixODBC project was first started in the early months of 1999 (by Peter Harvey) and was created as at that time the developers of iODBC (another open source ODBC implementation) were not then willing to LGPL the code, expand the API to include the current ODBC 3 API specification, and did not consider the addition of GUI based configuration tools worthwhile. iODBC now has these parts ...
OLE DB providers are analogous to ODBC drivers, JDBC drivers, and ADO.NET data providers. OLE DB providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle , Microsoft SQL Server , Sybase ASE , and many others.
It provides ODBC, JDBC, and OLE DB access to Adabas and enables SQL access to Adabas using COBOL programs. Search facilities may use indexed fields, non-indexed fields, or both. Does not natively enforce referential integrity constraints, and parent–child relations must be maintained by application code.
Database virtualization may use a single ODBC-based DSN to provide a connection to a similar virtual database layer. [clarification needed] Alluxio, an open-source virtual distributed file system (VDFS), started at the University of California, Berkeley's AMPLab. The system abstracts data from various file systems and object stores. [citation ...
