automatically convert the raw bytes to dictionaryand value is the actual value of the data column, such as int,short,guid,string and so on. By giving your users a schema, Orcamdf can skip a large amount of dependent metadata for parsing, so you can ignore data read failures that might result from possible metadata errors.Since the page header already gives the Nextpageid and Previouspageid properties, this allows the software to simply traverse all the pages in the linked list and parse the dat

the database engine for allocation and management. The following paragraphs are difficult to understand: my understanding, estimation is wrong! (IAM: is used to record which pages in a zone come from the same object, such as pigs in a unified area are coming to a farmer, and that data is recorded in an IAM page.) ） The Index allocation Mapping (IAM) page maps t

from the tool class. In many cases, the choice of inheritance relationships to describe the relationships between two classes is due to a lack of understanding of the inheritance relationship. The differences between IS-A and Has-a are discussed below. Is-a and Has-a differences: Is-a, as the name suggests, is "a", meaning that a class is one of another; Has-a is "one", meaning that a class is part of another class. The wrong use of inheritance instead of using a combination is to "has-a" a
