| 1. | Note : these functions depend on the locale settings of the server 注意:这些函数依赖于服务器的地区设置。 |
| 2. | Evaluation to candidate keys by functional dependencies in the database 数据库中利用函数依赖求解候选码的方法 |
| 3. | Information granules and granular computing on function dependencies in information system 信息系统函数依赖的信息颗粒原理与计算 |
| 4. | Unique , primary key , referential , check , and functional dependency constraints are supported 惟一约束、主键约束、参照约束、检查约束和函数依赖约束在这里都受支持。 |
| 5. | Similarly , if you schema bind a function , you cannot modify or drop the referenced objects and columns in a way that breaks the dependencies of the function 同样,如果将函数绑定到架构,也不能采用中断函数依赖关系的方式修改或删除被引用对象和列。 |
| 6. | The main research work is to make use of concept lattice structure to solve the problem of mining association rules , classification rules , and functional dependencies from data 研究工作的重点是使用概念格结构模型对关联规则、分类规则和函数依赖的发现问题进行求解。 |
| 7. | By propagating xml keys to relations as functional dependencies , we update xml data and it ' s storage over relational databases at the same time , we preserve the coincidence between them 通过把xml键约束映射为关系数据库中的函数依赖,在更新xml文档时,不但保持了xml文档本身的键约束,还使关系数据库和xml文档保持了一致。 |
| 8. | The indiscernibility lattice corresponding to indiscernibility context can be used to computing the reduct set of any subset of attributes in information system , and thus can serve as a framework for discovering 而不可区分背景所对应的不可区分格则可以用于信息系统中任意属性子集的缩减集计算,于是它可以用作一个框架结构来发现关系数据中所成立的函数依赖关系 |
| 9. | The author selected the rdb design software vfp , used the visual and object - oriented programming technique . in the end the command and communication database system structure has been constructed , based on e - r model , function - depended and standardization analysis 选择关系模型数据库设计软件vfp ,采用可视化面向对象的程序设计技术的,通过e - r模型、函数依赖和规范化分析,建立了指挥通信系统数据库体系结构。 |
| 10. | Based on functional dependence of relation algebra , the paper available expresses the coordination relation between primary and backup prection and it is fds which can generate directed basic loops and form optimal coordination sequences of protection setting , and accordingly achieve the optimal coordination of prections in the whole network . 本文充分运用关系代数中函数依赖的概念,有效地表达主后备保护配合关系? ?保护函数依赖集( fds ,即functionaldependencyset ,并用其自动生成网络有向基本回路,形成保护整定最优配合顺序,从而达到全网的保护最优配合。 |
