The project has 2 related sets of aims. As a language, RAQUEL is to : 1. be a pure relational algebra language (unlike SQL) as defined by Date & Darwen's "The Third Manifesto"; 2. incorporate a generalised extension of the ANSI-SPARC 3-layer DB architecture; 3. have the maximum ratio of functionality to conceptual complexity (as defined by Fred Brooks). As a DBMS, RAQUEL is to : 1. have an Open Architecture, enabling a variety of DBMS configurations of 'black box' code,...

This PL/SQL package converts a query with a sdo_geometry into an ESRI shape file and a shape file into a Oracle table. It can also convert a Oracle table into a dBase file and vice versa. Sample 1 - create a shape file (alk.shp, alk.shx, alk.dbf) of type 5 (=Polygon) from table MYTABLE with sdo-column="geo" and SDO_GTYPE=3003: select zvk_shape.write_shp('DATA_PUMP_DIR','alk', 'select t.C01 "NAME", t.C20 "FLST", t.GEO from MYTABLE t where t.C02 = ''ALK'' order by t.C01','GEO',5) "alk" FROM dual;
