OpenLink Virtuoso 5.0.9 (Open-Source branch)

OpenLink Virtuoso is a scalable, high-performance SQL-200n compliant object-relational database engine. It provide sophisticated database management for SQL, XML, and RDF. All interaction with Virtuoso occurs via its support of industry standard query languages, protocols, APIs, and data formats such as: ODBC, JDBC, OLE-DB, ADO.NET, XMLA, SQL, SPARQL, XQuery, SOAP, HTTP, WebDAV, SyncML, Atom (Publishing and Syndication), RSS, RDF, and more. License: GNU General Public License (GPL) Changes:
This version brings performance optimizations for the SQL and SPARQL engines and ODBC and JDBC drivers. New features include: an Excel MIME-type output option in the SPARQL endpoint; triple options bif:contains and transitivity; new RDF-generating cartridges with UMBEL lookups for the Sponger; support for very large HTTP client requests; a sparql-auth endpoint with digest authentication; and support for the Ubiquity Firefox plugin. There are also minor bugfixes for memory leaks, SPARQL "select distinct", and various SQL query syntax handling. XHTML validation is done in the ODS application suite. Image

NAME
grass-sqlite - SQLite driver SQLite driver SQLite driver in GRASS Creating a SQLite database GRASS is automatically creating the SQLite database if it is not yet existing when the first table is created in the SQLite database. It is sufficient to define the connection (see next step). Connecting GRASS to SQLite The database name 'sqlite.db' is at user's choice. Also the file storage location can be freely chosen. If the database does not exist, it will be automatically created when database content is created: # example for storing DB in mapset directory (keep single quotes): db.connect driver=sqlite database='$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite.db' db.connect -p Supported SQL commands All SQL commands supported by SQLite (for limitations, see SQLite help page: SQL As Understood By SQLite and Unsupported SQL). Operators available in conditions All SQL operators supported by SQLite. Browsing table data in DB A convenient SQLite front-end is sqlitebrowser. To open a DB file stored within the current mapset, the following way is suggested (corre- sponds to above database connection): eval `g.gisenv` # use double quotes: sqlitebrowser "$GISDBASE/$LOCATION_NAME/$MAPSET"/sqlite.db SEE ALSO
