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.
The SQL Editor, based on RSyntaxTextArea by fifesoft.com, provides syntax highlighting. It can open, create, save and execute files containing SQL statements. SQuirreL supports simultaneous sessions with multiple databases. This allows comparing data and sharing SQL statements between databases. [4] SQuirreL runs on any platform that has a JVM.
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 can also provide access to hierarchical data stores such as ...
[citation needed] ODBC is a widely used data access interface for relational database management systems RDBMS. DEC and Oracle licensed Simba products in 1993. [ citation needed ] In 1994, Attachmate , Liant and PageAhead jointly developed a product that would allow Attachmate to use PageAhead's SDK products to build their original QuickDB server.
Trino is an open-source distributed SQL query engine designed to query large data sets distributed over one or more heterogeneous data sources. [1] Trino can query data lakes that contain a variety of file formats such as simple row-oriented CSV and JSON data files to more performant open column-oriented data file formats like ORC or Parquet [2] [3] residing on different storage systems like ...
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 or non-indexed fields or both. Does not natively enforce referential integrity constraints, and parent-child relations must be maintained by application code.
