aRT: FAQ
- Q: Which DBMS' does aRT supports?
- A: Currently only MySQL and Postgres.
- In principle aRT can support any DBMS supported Terralib. All is needed is to extend aRT for other DBMS already supoported by Terralib. Contributions to extend the list of supported DBMS are welcome.
- we should have a road map to guide such expansions!
- Q: Can I run aRT without a DBMS?
- currently no. There are plans to implement this.
- Q: how does aRT get to know which DBMS do I have?
- aRT (on LINUX) has a
configuretool which runs during the instalation and searches for the supported BDMS available in the system
- Q: Why do I get
IDfromgetPoints()andidfrom getData()on a layer?- A: This is not a bug, but a feature. sp package uses ID to represent the identification of spatial objects. We just follow the pattern. Points do not need to have an identification so we introduced an ID in order to follow the spatial model for lines and polygons. Data from attribute tables are "as is". If you want to put together attributes and geometries fearlessly, then use themes.
