Be " normally " if a) set up this Object Management group and its supervisor status, then from the types index management, obtain the inner EDTypeID that uses of its management system;
B) otherwise, directly arrange the inquiry empty object information
3, utilize EDTypeID, on the index and managing listings of its Object Management group class, retrieve
A) the name information EDOName(of inspection electric power object is unique, and is unique in the classification at least) and in the object indexing tabulation of the type Object Management group tabulation, check the management of whether having set up this object;
B) if set up management and state for " normally ", from tabulating, its object indexing obtains its EDOID; Determine " normally " time and query time matching, as meet and then carry out Object Query; Otherwise, do not carry out follow-up inquiry work, the empty object information of inquiry directly is set;
C) if built standpipe reason but state be " deletion " directly arranges to inquire about empty object information.
4, utilize the EDOID that obtains, anchored object position during direct Object Management group in the type is tabulated is according to the object information of temporal information structure time version.
A) current information, directly return attribute value;
B) fixed time, need to from each attribute time sequential value, obtain the attribute value with time match; Structure has the constantly electric power object information of numerical value of complete attribute, returns.
[4] qualitative attribute (capacity and performance) guarantees mechanism
1, multi-level Indexing Mechanism: can be according to type, object, attribute, even the Index Design of dividing for more multi-layered time, guarantee the direct location of management object; And support the modification of regime type, attribute, support the mutable object attribute management.
2, be association of activity and inertia: the static store index information; Index information is take change information not as first-selected;
The dynamic memory change information, and define with minimum information unit (object).
3, internal memory/disk combination: according to internal memory and the disk storage resource situation of computer system, and according to generation and the handling characteristics of data object of management, automatically set up the data storage of the interior external memory combination of appropriate size standard; General index information keeps memory management, and recorded information, and the frequency that especially changes is low, the perhaps low type object of frequency of utilization, the storage management technique of taking interior external memory capable of regulating ratio at regular time and quantity.
4, quality of data inspection: the electric power object has also designed the behavior operational administrative that meets its basic physical features except basic attribute management, comprises the property value quality management in the type object, object relationship bookkeeping etc.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present invention.
