Abstract
The invention belongs to a data base system field and provides a spatial database engine system, especially one applied in geographic information system (GIS). The invention provides a spatial database engine system which can directly store three dimensional data of geographical space and does not need conversion; meanwhile the system can carry out operations such as direct reading and editing, etc. on three dimensional data. The invention realizes a direct storage of three dimensional geographic information data and provides a great database system support to GIS system.
Description
Technical field
The present invention relates to a kind of spatial database engine system, especially a kind of spatial database system that is applied in the Geographic Information System (GIS) belongs to the Database Systems field.
Background technology
Current, along with the development of infotech and the continuous expansion of application, geographic information system technology has obtained development at full speed.Because GIS is the strategic technology that is related to national security, therefore exploitation has the homemade generalized information system platform of independent intellectual property right, and research and grasp forward position gordian technique among the GIS has very important meaning to development and the application of China GIS.
And the exploitation of generalized information system must rely on and gather geodata, then data is concluded, and arrangement is set up database and deposited geodata, supports with the data as generalized information system.That uses in generalized information system at present mostly is system R, the 2-D data relation can only be deposited by the relational data system, as the conversion that runs into multidimensional data relation and then need to carry out data just can deposit, and this conversion can influence the construction cycle and the operational efficiency of generalized information system.
Along with the continuous development and the renewal of advanced database technology and infotech, the Database Systems product that can deposit the three-dimensional information data will have the very big market space.
Summary of the invention
The objective of the invention is to: at the deficiency of above prior art existence, propose a kind of spatial database engine system, the three-dimensional data of geographical space can directly be deposited by this system, need not transform, simultaneously also can carry out three-dimensional data and directly read operations such as editor.
In order to reach above purpose, a kind of spatial database engine of the present invention system should comprise following assembly:
The data storage area---be used to store the memory cache district of geographical spatial data;
Addressing component---be used for according to reading command, parse the functional module of deposit data address;
The data read assembly---after the addressing component addressing, carry out reading of data in the address;
Storage medium---be installed in the computing machine, be used to store data.
When a kind of spatial database engine of the present invention system carries out data manipulation, comprise following steps:
Step 1: after at first the geographical spatial data information of gathering being carried out induction-arrangement, progressively be entered in the data storage area, physical record is corresponding address in the storage medium in the data storage area;
Step 2: in logging data, each data of typing are deposited this data corresponding address down in addressing component;
Step 3: during reading of data, accept to read request by the data read assembly, parsing needs the data address that reads in the order, carry out the data comparison then in addressing component, find match address after, sense data.
The present invention has realized the direct storage of three-dimensional geographic information data, provides powerful Database Systems support to generalized information system.
Embodiment
Embodiment one
The spatial database engine system of present embodiment should comprise following assembly:
The data storage area---be used to store the memory cache district of geographical spatial data;
Addressing component---be used for according to reading command, parse the functional module of deposit data address;
The data read assembly---after the addressing component addressing, carry out reading of data in the address;
Storage medium---be installed in the computing machine, be used to store data.
When a kind of spatial database engine system of present embodiment carries out data manipulation, comprise following steps:
Step 1: after at first the geographical spatial data information of gathering being carried out induction-arrangement, progressively be entered in the data storage area, physical record is corresponding address in the storage medium in the data storage area;
Step 2: in logging data, each data of typing are deposited this data corresponding address down in addressing component;
Step 3: during reading of data, accept to read request by the data read assembly, parsing needs the data address that reads in the order, carry out the data comparison then in addressing component, find match address after, sense data.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
