78 results about "Connection string" patented technology

In computing, a connection string is a string that specifies information about a data source and the means of connecting to it. It is passed in code to an underlying driver or provider in order to initiate the connection. Whilst commonly used for a database connection, the data source could also be a spreadsheet or text file.

Unique session storage design

A system and method for providing user session state across various networked machines is disclosed. The system encompasses a session saver and a sessions database centrally maintained for access by a plurality of computing devices. The system indexes each stored variant by a user defined key and a descriptive variable name. The session saver is a drop in replacement for the IIS session object that provides session state without using cookies. The session saver is divided into various subcomponents, including Csaver for providing the COM interface, OleDbSessionTable to read and write the data from an OLE database, Cconnection for retrieving a connection string from a UDL file, RegistryInfo that reads the location of the UDL file from the memory, StorageVariant enabling storage of variants in any properly configured OLE DB provider, and CcomVariantEx. Any of the operations servers generates a session key when initially contacted by the user and the session saver stores the session key and variables associated with the particular session, such as account numbers, passwords accepted, and so forth. These session keys and stored variables are available to any of the other operations servers and a procedure for retrieving these keys and variables is performed each time a session is either commenced or resumed. Each generated session key is unique and non predictable such that multiple operation servers can simultaneously generate keys without conflict.

Method for zero-modification migration of application program under heterogeneous database platforms

The invention discloses a method for the zero-modification migration of an application program under heterogeneous database platforms. An architecture of the method comprises a server side and a client side; the server side consists of two compatible heterogeneous database platforms which are respectively called an original database platform and a new database platform, and the compatibility of the database platforms comprises data types and SQL (Structured Query Language) sentences; the client side consists of the application program and an application program loader, and the application program accesses the database platforms by using an ADO (ActiveX Data Objects) and OLE DB (Object Linking and Embedding Database) mode and is connected with the database platforms by using an ADO and OLEDB connection character string; and the application program loader starts the application program, searches from a memory, replaces a database connection character string of the application program, and closes the running of the application program. According to the method for the zero-modification migration of the application program under the heterogeneous database platforms, the seamless migration and switchover between the two database platforms can be achieved, the workload for application program migration is greatly reduced, and the human, material and financial resources are saved.
