15 PL/SQL Web Services Simple Search and DML interfaces PL/SQL packaged functions can be exposed as simple web services Easy to develop XML-based protocol for accessing services on the Web by using XML syntax to send commands over HTTP JDeveloper provides many features to help create and deploy web services These web services can be deployed in any J2EE container or APEX These are useful to expose specific database search or DML operations are web services to other components in a system 15

16 Why not OGC web services? OGC web services are useful for systems that need to publish services over the web to other institutions or departments They are useful for well defined sets of operations Overkill if simple interactions are required between different components of a workflow in a single system or closely related systems 16

17 Simple Search Example Create a PL/SQL function CREATE FUNCTION FIND_NEARBY_RISKS( LONGITUDE NUMBER, LATITUDE NUMBER) RETURN VARCHAR2 AS Result varchar2(3000); BEGIN SELECT XMLELEMENT( xmlagg(feature_name) ) into result FROM features_of_interest a WHERE SDO_ANYINTERACT(a.geometry, sdo_geometry(2001,8307, sdo_point_type(longitude,latitude,null), null, null)) = TRUE ; return result; END; 17

18 Publishing and Using the web service Jdeveloper makes it easy to take the PL/SQL function and publish it a s web service No code require, all widget driven OTN Jdeveloper pages have examples Use HTTP GET methods to use the service This will return an XML document with potential features of interest that are at risk near the incident location These type of services are easy to integrate into the workflow of a system that requires results based on spatial searches 18

19 Simple DML Example Create a PL/SQL function CREATE FUNCTION CREATE_INCIDENT( LONGITUDE NUMBER, LATITUDE NUMBER) RETURN VARCHAR2 AS Result incident_number; BEGIN incident_number := service_incidents_seq.nextval; INSERT INTO service_incidents values (incident_number, sdo_geometry(2001,8307, sdo_point_type(longitude,latitude,null), null, null)) ; commit; return incident_number; END; 19

20 Publishing and Using the web service A field technician wants to report an incident at a certain location Use HTTP PUT method to use the service d {longitude: longitude: 37} This will create an entry in the incidents table and trigger an event to generate a service request to process the event Database triggers should be used to automatically trigger these services requests based on the incidents 20

21 Provide Spatial analytics as web services Don t need to have SQL access to add spatial capabilities to an application Many times simple spatial search interfaces can integrated into different components of a system using PL/SQL based web services Don t need a separate GIS system if the application does not have direct access to the Spatial database Use the database services as much as possible to truly take advantage of enterprise wide spatial data 21

22 Hierarchical Report Generation Requirement Generate reports and maps using custom or standard geographic entities Provide drill down and drill up capabilities Hierarchy can be geometry based or name based Solution Use MapViewer for maps and reports Use commercial or open source data sets to build the hierarchies And associate these hierarchies with the application data 22

23 Hierarchy Examples Customer locations have an address Find the aggregate information for all customers in a city/county/state/ country Map interface to drill up and drill down to navigate through the hierarchy and visualize the aggregate information at different levels 23

24 Creating Hierarchical Data Model Many data sources available for coarse level admin area boundary data Oracle bundles HERE data (certain levels of administrative boundaries) sets with the database Open source data sets are also readily available Create a COUNTRY_HIERARCHY table with these columns (AREA_ID, NAME, ADMIN_LEVEL, PARENT_AREA_ID, GEOMETRY) Populate the parent_area_id column using SDO_RELATE operations 24

25 Using Hierarchical Data Model Geometry based hierarchy Associate each customer with the lowest level of the hierarchy In this example, lets say city is at level 4, county at level 3, etc. Associate the customer records with the city level admin area Once this hierarch is established it is easy to calculate aggregate metrics for different customer attributes at different admin areas Using SQL it is then easy to find the number of customers in each city/ county/state/country MapViewer api can be used to define themes that will show aggregate customer data at each level of the hierarchy All of this can be done dynamically on the operational data 25

26 Custom Hierarchies Geometry hierarchy Users want to create own geometry regions Define hierarchies based on user defined collections of geometries Hierarchies are defined based on business rules and do not necessary follow admin hierarchies Examples: postal_codes/sales_territories/sales_regions, etc. 26

27 Custom Hierarchies Data sources and session settings Session (spatial) content and state Data editing tools 27

28 MapViewer Web-based Editor A web-based spatial data editing tool (java applet) Supports versioned, concurrent editing through editing sessions Supports Workspace Manager Supports geometry model All aspects of an editing session are saved in database 28

29 APEX Map Application 29

30 Spatial enabled Applications in APEX Spatial data in tables First approach: two NUMBER columns What about lines and polygons? Spatial processing SQL, PL/SQL Visualization on a map Adding new spatial data via the browser Geocoding Spatial queries: Within Distance Nearest Neighbors Spatial Intersections 30

31 1) Map 31

32 2) Geocoder 32

33 3) Spatial Query: Within Distance 33

34 4) Spatial Query: Anyinteract 34

35 APEX and the Database provide everything you need... Spatial Data Type: SDO_GEOMETRY Spatial functions in SQL and PL/SQL Oracle elocation Map Service Oracle elocation Geocoder Service APEX plugins and widgets APEX Sample application 35

36 Sample Geolocation Showcase 36

37 Oracle Maps Utility Plugins 37

38 Step 1 SPATIAL DATA 38

39 Create a table for spatial data Can store points, lines, polygons and complex geometries Database provides indexing, query and processing capabilities create table my_spatial_images( id number(10) not null, image blob, thumbnail blob, file_name varchar2(200) not null, mimetype varchar2(200), geometry sdo_geometry, exif xmltype, datetime timestamp with time zone, constraint my_spatial_images_pk primary key (id) ) 39

40 Spatial tables need additional tasks Maintain spatial metadata Create an index mandatory for spatial queries begin - - create metadata for spatial table - - coordinates are lon/lat and over the whole world apex_spatial.insert_geom_metadata_lonlat( p_table_name => 'MY_SPATIAL_IMAGES', p_column_name => 'GEOMETRY' ); end; create index MY_SPATIAL_IMAGES_SX on MY_SPATIAL_IMAGES (GEOMETRY) indextype is MDSYS.SPATIAL_INDEX 40

41 Geocoding: APEX Plugin Dynamic Action Plugin 41

42 Step 2 VISUALIZATION ON A MAP 42

43 Architecture Oracle elocation Service with Map Database Background Maps Client Browser Geocoding Reverse Geocoding APEX database APEX Pages and objects to be shown on the map 43

44 Oracle MapViewer and Oracle Maps Map Rendering based on spatial data in the database Alternatives in APEX Own Installation of Fusion Middleware MapViewer Use Oracle elocation Service maps.oracle.com Programmers Interfaces APEX Plugin Oracle Maps JavaScript API 44

45 Oracle Maps APEX Plugin 45

46 Step 3 SPATIAL QUERY AND ANALYSIS 46

47 Within Distance Search WHERE Clause: SDO_WITHIN_DISTANCE Geometry column must be spatially indexed Input Parameters Geometry column to search in Search Geometry Distance Unit to use 47

48 Nearest Neighbor Search WHERE Clause: SDO_NN Geometry column must be spatially indexed Input Parameters Geometry column to search in Start geometry Maximum Distance Max. neighbors Unit to use select * from feature_table t where sdo_nn( t.geometry, start_geometry, 'distance=xx unit=km' ) = 'TRUE' 48

49 BUILD YOUR OWN APPLICATION 49

50 Your own application... 50

51 APEX and the Database But you can go further... Use your own map server... Use own map styles or own map data Deep Integration between database and map server Use your own geocoding facility Geocoder directly embedded in the database No HTTP requests any more And you can still use the APEX plugins and widgets 51
