PSQL v12 / September 2015 Development status Active Available in English, Japanese, NotOnlySQL Website Pervasive PSQL is an -compliant (DBMS) developed. It is optimized for in applications and used in several different types of packaged offered by (ISVs) and (OEMs). It is available for (SaaS) deployment due to a file-based architecture enabling partitioning of data for needs. Applications can store the data and the relationships in in a (RDBMS) or store the data in a -less way with no fixed. Pervasive PSQL runs on system platforms that include, and. Both and editions of Pervasive PSQL are available. Editions are also specifically designed for different computer networking needs, such as, and highly virtualized environments, including.

The original name for Pervasive PSQL was. Pervasive Software was acquired by in 2013. Contents. Uses and customers Because Pervasive PSQL is used for embedded databases, and sold indirectly, it is not well known. Pervasive PSQL is embedded by OEMs like, maestro. Technologies, ABACUS Research AG (Switzerland), and Unikum (Sweden) in packaged software applications that address the accounting, finance, retail, point-of-sale, entertainment, reservation system, and medical and pharmaceutical industry segments.

“Users include Novell, Microsoft, PeachTree Software, Fair Isaac, Disney World, Radio Shack, Cardiff and others.” The accounting industry formed a large part of its market in 2007. Historically, Pervasive PSQL served as a DBMS for. DBMS architecture.

See also: Pervasive PSQL supports stand-alone, client-server, and (SaaS). The central architecture of Pervasive PSQL consists of two engines: (1) the, known as MicroKernel Database Engine (MKDE) and described by Pervasive Software as a engine and (2) the engine, known as SQL Relational Database Engine (SRDE). Both engines can access the same data, but the methods of differ. MicroKernel Database Engine Pervasive’s transactional database engine, the MicroKernel Database Engine, interacts directly with the data and does not require fixed data schema to access the data.

It uses key-value store to store and access the data. Calls to the MKDE are made programmatically with API rather than through the use of a; therefore, Pervasive PSQL does not have to the request. This places the MicroKernel Database Engine in the category of databases. Low-level API calls and memory caching of data reduce the time required to manipulate data. The MKDE operates in complete database transactions and guarantees full ACID (, ). If a transaction does not fully run its course due to an external event such as a power interruption, the data remains in the state in which it existed before the transaction began to run. In the MKDE, records are stored in which are roughly equivalent to the tables of a relational database engine.

It supports multiple on a record and therefore multiple indexes in the file. The MKDE caches data in memory to facilitate performance. When a call is made to the MKDE, data is searched first; physical storage is searched if there is no cache of the data. Settings for caches can be pre-configured by to optimize Pervasive PSQL performance for their applications. Relational Database Engine The second database engine, the SQL Relational Database Engine or SRDE, operates in a manner similar to other relational database engines, that is, through the support of queries. SRDE parses queries and sends them to the MKDE to run. The SRDE implements.

PSQL v12 SP1 New Features. Online Defragmenter. Automatic Defragmentation - The online defragmenter can now be set to run automatically - you don't have to manually.

I started the CD with drivers for XP, click in the Device Manager, click on the 'Audio Device on High Definition Audio Bus' and click on 'Update Driver Software', than 'Browse My Computer for Driver Software'. Drivers were installed without a problem. I found a way to install the drivers. Ga-81915pm drivers windows 7.

Significant other features include relational, and temporary tables. SRDE extends its functionality by supporting, and. In addition to its support for SQL-92, the SRDE supports several significant features of: COBOL and COBOL OCCURS and VARIANT records. Additional features Pervasive PSQL provides the following additional features:. aware.

with Pervasive DataExchange Interfaces. Pervasive PSQL fall into two categories: management interfaces and interfaces. Management interfaces Pervasive Software provides the management interfaces Distributed Tuning Interface (DTI) and Distributed Tuning Objects (DTO), a (COM) (wrapper) for the DTI. These provide for configuration, monitoring, and diagnostics of Pervasive components. COBOL can also provide component management through a COBOL connector that can talk to DTI.

Application interfaces All other interfaces exist for data manipulation purposes. Btrieve, (JCL), COBOL, and provides direct access to the MicroKernel Database Engine (MKDE).; v3.51 and 2 for Core, Level 1, and Level 2; and provide access to the SQL Relational Database Engine (SRDE). Pervasive Direct Access Components (PDAC) are a set of (VCL) components that enable direct access to both MKDE and SRDE for and environments. Tools Pervasive provides designed to facilitate administration and use of Pervasive PSQL. There are graphical and utilities in, Linux, and environments. Pervasive Control Center (PCC) is the main utility that enables the user to create and manipulate databases and tables, to access and clients, to set configuration, properties, and to edit data.

Through PCC, the user can access a series of other utilities:. License Administrator utility handles activities. Notification Viewer utility displays licensing-related messages logged by the PSQL engine. Monitor utility checks and displays activities and attributes of both engines, including usage, information, and communication statistics. Pervasive System Analyzer utility tests the connections between the engines and within the and displays information about system components. Maintenance utility enables users to create and edit schema-less files.

Rebuild utility enables users to convert and rebuild files in its MKDE file format. DDF ( file) Builder utility enables SQL users to create and modify table schemas for data stored in the MKDE, thus providing relational access to the data. Query Plan Viewer enables SQL users to analyze for. Function Executor assists developers with, and by simulating direct operations into MKDE and providing a view into the schema-less data. Versions See, beginning with Pervasive.SQL 7. Editions and licensing Editions There are four editions of PSQL: Pervasive PSQL Client, Pervasive PSQL Workgroup, Pervasive PSQL Server, and Pervasive PSQL Vx Server. Pervasive PSQL Client is designed for use with Pervasive PSQL Server and Pervasive PSQL Vx Server in a client-server network.

Pervasive PSQL Workgroup edition is intended for or small workgroup, peer-to-peer, installations. Pervasive PSQL Server edition is intended for configurations that have at minimum ten connections and it is scalable up to thousands of concurrent network users in client-server network and on the level. PSQL Vx Server runs under in a environment. It is designed for customers “who need support for highly virtualized environments enabling live migration, fault tolerance, high availability and cloud computing.” Licensing Pervasive Software uses two different models, user-count licensing and capacity-based licensing.

In user-count licensing, each specifies a licensed user. At any given moment, that many users can be connected to the engine.

Capacity-based licensing is based on the amount of performed by the database engine. It measures data in use and sessions in use. This license model is designed to facilitate Cloud computing and highly virtualized environments. Both PSQL Server and PSQL Workgroup use a user-count licensing model, while PSQL Vx Server uses capacity-based licensing.

Limitations. Pervasive PSQL lacks some of the, and reporting services built into database engines such as and. Pervasive PSQL lacks Unicode support in the RDBMS layer. Pervasive PSQL lacks the ability to perform. References. ^ Wiejers, Ben (December, 2000 (updated October 2001)). Data Access Worldwide.
