查询词典 sequential file

If batch processing is acceptable, a sequential file organization is probably best.

如果可采用批处理的话，那么一个顺序文件结构可能是最好的了。

Our experiments show that, in most cases, the performance of such an implementation is as good as that of Intel's native PFS. In other cases, such as small sequential file access, large I/O requests and collective I/O, the SIO implementation is much more stable and better than that of the PFS.

我们的实验结果表明，在大多数情况下，这种实现方式下PFS的性能与原始的PFS性能相当，在某些情况下，如较小的顺序文件存取、较大的I/O请求、和Collective I/O，SIO-LLAPI上的PFS实现比原始的PFS性能更稳定和更好。

Moreover, it is not as efficient as sequential file organization for listing large number of records.

此外，它不是高效率的顺序列出文件组织大量记录。

The disadvantage of sequential file organization is that records must be ordered in a particular way and so searching for data is slow.

直接解决组织：相反的储存记录序列，直接文件组织，有时被称为随机文件的组织，存储记录在没有特定的顺序。

Sequential organization: Sequential file organization stores records in sequence, one after the other.

数据记录必须测序或命令之前，该文件是建立在存储介质。

For example, if the search is for points stored in a random sequential file, all records in the file must be queried to ascertain whether the desired points have been located.

在连续记录的档案中搜寻资料是很费时的，例如寻找纪录在某个连续档案中的点位，不管是否找到需要的点位，档案中的所有纪录都会被要求查询，因此未整理的档案只建议储存较小量的资料。

以多个相互关联的不同类型控制网为信息表示对象，将控制网的各种观测数据、观测仪器、平差计算数据、文档数据和描述性数据设计在一个数据集中，并以顺序文件形式存储。

Discrete control points being a information description object, a datasheet can be designed to include all kinds of coordinate data, coordinate explanation data, station occupation description data, file data of a single point, stored in the form of sequential file.

以离散的点位为信息表示对象，将一个点的各种坐标数据、坐标说明数据、测站描述数据、文件数据等设计在一张数据单中，并以顺序文件形式存储。

This paper discusses the organizing principle of knowledge library in expert system and suggest that the Sequential File, Index File, Multichain File, Backcomposing File, Hash File, etc can be adopted to organize knowledge library and the corresponding program is designed in the Prolog Language.

论述了专家系统中知识库的组织原则，对在计算机上如何实现知识库的物理组织问题，提出可以采用顺序文件、索引文件、多重链接表文件、倒排文件及散列文件等方法来组织知识库。
