Active Record associates a class with a table and dynamically adds an attribute to each class for every column in the database. ActiveRecord将类和表关联起来,并按照数据库中的每一列给每个类动态地添加一个属性。
For standard validations like checking the name, length and format of an attribute, we can make use of validations provided by Active Record. 对于标准的检验(比如检查属性的名称、长度和格式),可以使用ActiveRecord提供的检验。
Our country file's traditional understanding is takes the historic record the file the essential attribute. 我国档案界的传统认识是将原始记录性作为档案的本质属性。
Development of Modern Medical Record and Its Legal Attribute 现代病历的发展及其法律属性
The proposed method partitions record set according to decided attribute values, and then detects approximately duplicate records in each class of decided attribute value. 该方法根据关系表的决定属性值划分记录集,并在每个决定属性值类中检测相似重复记录。
But finally from the judicial practice angle, inspected the world main shipping country based on definitely to record a name the bill of lading real right attribute to persist in reality the certificate sold goods the principle unitizing tendency. 最后从司法实践角度,考察了世界主要航运国家基于肯定记名提单物权属性而在实践中坚持凭单放货原则的统一化趋势。
Having no restriction of main memory and record number and attribute number of training database, the algorithm can output practice and accurate decision tree. 该算法没有训练数据库需存储于内存的限制,对训练库也没有记录个数及属性个数的限制,能生成简练、精确的决策树。
The method that a decision tree model is used to classify a record is to find a path that from root to leaf by measuring the attributes test, and the attribute on the leaf indicates to which the record belongs. 通过决策树模型对一条记录进行分类,就是通过按照模型中属性测试结果从根到叶找到一条路径,最后叶节点的属性值就是该记录的分类结果。
Based on the properties of attribute set of connection record sequence, the detecting method of conditional random fields based on attribute set is proposed, merging into the way of feature set. 根据连接记录序列属性集的特点,融入属性集方法,提出了基于属性集的条件随机域的检测方法。
Simply to compare the different objects of the generalized decision values and record the corresponding conditional attribute values, so the shortcomings of checking the property values and generalized decision value whether conflict or not in calculation process in the original literature was avoided and optimize the algorithm. 这样避免原有文献中计算过程中反复检查属性值对与广义决策值是否冲突的缺点,从而优化了算法。
