Pervasive Odbc Client Interface Driver Downloadl: Tips and Tricks for Optimizing Your Data Integrati

NOTE: The PSQL Workgroup engine is only needed for installations where a single user workstation will be running RDP. All other machines including the IRM, interface computers and RDPWin workstations can run on the PSQL 10 client (service) installation

The product was launched in February 1982 by SoftCraft, a firm located in Austin, Texas, by Doug and Nancy Woodward. Doug became the vice-president and handled software development, Nancy became the president of the company. They released a number of versions over the next few years: in February 1983 they released the Btrieve 2.x series, and when MS-DOS 2.0 developed support for file and directory handles, they released Btrieve 3.0. When MS-DOS 3.1 standardised its internal interfaces in March 1985, they released Btrieve 3.1 C/S one month later, which had network and client/server support. In February 1986, Btrieve 4.0 was released, and when the 4.1 upgrade was released it gained support for extended key types and supplemental indexes.

Applications make a function call to WBTRCALL.DLL, a loader and requester interface. The loader and requester module verify the BTI.INI configuration file is correctly set up to load the client-based Btrieve engine. In turn, this loads the local interface to the btrieve engine (WBTRLOCL.DLL). If necessary, this local interface loads the Btrieve engine (WBTR32.EXE) into memory and sends the necessary database requests to it. The database engine then calls various Win32 system libraries to perform file operations on the database files.[7]

As with the client-based interface, the Btrieve-based application makes a call to the WBTRCALL.DLL loader and requester interface library. This library checks the BTI.INI file to see if it needs to access data on the local system or whether it needs to access data on a remote server. If it needs to access the server, then it uses the Windows version of DPMI to access a DOS-based requester named BREQUEST.EXE. The requester then establishes a network connection to the server, which processes the request and passes back a message to the requester when the database request is completed.

On Windows 95, the MKDE interface (a Windows dynamic link library (DLL) called WBTRV32.DLL) determines what database access method is in use via the configuration file. If it detects both the client/server and workstation engines are installed on the same machine, it checks whether the target is set to workstation or server. If running on Windows NT and the server process NTMKDE.EXE is running along with the standalone workstation process W32MKDE.EXE it looks in the registry to determine if the target is a server or workstation. In both cases, if the MKDE interface is set to workstation, (the "Standalone workstation" configuration) it uses the MKDE (W32MKDE.EXE) to access the file directly. If it is set to server, the MKDE interface on the client uses a communications module (on Windows 95 this is W32BTICM.DLL, on Windows NT this is NTBTICM.DLL) that "talks" to the server. The server itself has its own matching communications module (again either W32BTICM.DLL or NTBTICM.DLL) that resides on the mapped drive. The server DLL communicates with the server MKDE (NTMKDE.EXE) which updates records, then sends a confirmation that the operation succeeded, back through the communications module to the client.[10]

Pervasive PSQL v11 was released in September 2010. One of the key drivers of the engineering effort behind Pervasive PSQL v11 was the redesign of the database engine to increase performance and scalability on multi-core CPU's. Pervasive PSQL v11 optimizes parallel threads performing similar activities, allowing the database to engage multiple cores during task execution. PSQL v11 also provides enhancements to the low-level synchronization mechanisms in the navigational interface. Multiple users can read the same cached file pages simultaneously and their operations can proceed on independent cores. Non-user activity such as checkpoints and log management can run on separate cores and multiple users accessing independent files can proceed on different cores.[14]

DBeaver is an Open-source and Multi-Platform Administration Database Tool that allows you to query data present in various database environments. In other words, DBeaver is a SQL client that connects with more than 80 database applications like MySQL, PostgreSQL, Oracle, Snowflake, and much more. With DBeaver editor, you can easily query data present across various databases using SQL commands. In addition, DBeaver is compatible with any external database application that has its own JDBC or ODBC driver.

Usually, developers use the web interface of Snowflake that serves as an interactive GUI tool to write SQL commands or queries for working with data. However, you can also connect external tools like Command Line Interface, JDBC drivers, ODBC drivers, and Node js drivers with the Snowflake database. On embedding such tools, you can run SQL commands to query data present in the Snowflake database directly from any respective external application that supports driver or CLI connectivity.

The Oracle OCI (Oracle Call Interface) driver requires Oracle client software to be installed on the user's machinein order to connect to the database. This driver uses native methods and is platform specific.

defaultRowPrefetch: Oracle JDBC drivers allow you to set the number of rows to prefetch from the server while the result set is being populated during a query. Prefetching row data into the client reduces the number of round trips to the server. A typical value for this property is 10. 2ff7e9595c
