See Also connection pool, connection string, Connector/NET, Connector/ODBC, DSN, host, port.  A cache area that allows database  connections  to be reused within the same application or across different applications, rather than setting up and tearing down a new connection for every database operation. This technique is common with  J2EE  application servers.  Java  applications using  Connector/J  can use the connection pool features of  Tomcat  and other application servers. The reuse is transparent to applications; the application still opens and closes the connection as usual. See Also connection, Connector/J, J2EE, Tomcat.  A representation of the parameters for a database  connection , encoded as a string literal so that it can be used in program code. The parts of the string represent connection parameters such as  host  and  port . A connection string contains several key-value pairs, separated by semicolons. Each key-value pair is joined with an equal sign. Frequently used with  Connector/NET  applications; see Creating a Connector/NET Connection String for details. See Also connection, Connector/NET, host, port. See Also API, client, Connector/C++, Connector/J, Connector/NET, Connector/ODBC.  MySQL Connectors provide connectivity to the MySQL server for  client  programs. Several programming languages and frameworks each have their own associated Connector. Contrast with the lower-level access provided by an  API .  Connector/C++ 8.0 can be used to access MySQL servers that implement a document store, or in a traditional way using SQL queries. It enables development of C++ applications using X DevAPI, or plain C applications using X DevAPI for C. It also enables development of C++ applications that use the legacy JDBC-based API from Connector/C++ 1.1. For more information, see MySQL Connector/C++ 8.0 Developer Guide. See Also client, connector, JDBC.  A  JDBC  driver that provides connectivity for  client  applications developed in the  Java  programming language. MySQL Connector/J is a JDBC Type 4 driver: a pure-Java implementation of the MySQL protocol that does not rely on the MySQL  client libraries . For full details, see MySQL Connector/J 8.0 Developer Guide. See Also client, client libraries, connector, Java, JDBC.  A MySQL  connector  for developers writing applications using languages, technologies, and frameworks such as C# ,  .NET ,  Mono ,  Visual Studio ,  ASP.net , and  ADO.net . See Also ADO.NET, ASP.net, connector, C#, Mono, Visual Studio.  The family of MySQL ODBC drivers that provide access to a MySQL database using the industry standard Open Database Connectivity ( ODBC ) API. Formerly called MyODBC drivers. For full details, see MySQL Connector/ ODBC Developer Guide. See Also connector, ODBC.  A version of the  mysql  and  mysqli APIs  for  PHP  optimized for the Windows operating system. See Also connector, PHP, PHP API.  A read operation that uses  snapshot  information to present query results based on a point in time, regardless of changes performed by other transactions running at the same time. If queried data has been changed by another connection pool connection string connector Connector/C++ Connector/J Connector/NET Connector/ODBC consistent read Connector/PHP 6143
