...]} The content in square brackets and the number of elements in the container are optional. nested definitions can also be performed. Example: Userrecord: = SEQUENCE { Name SEQUENCE { First ia5string, Last ia5string }, DOB utctime } The structure in the C language is roughly translated as follows: Struct userrecord { Struct name { Char * first, Char * Last }; Time_t DOB; } It is roughly translated into the following records in the Object Pascal Language (Object Pascal does not

compete for resources with him. After reading the book, the next customer can come in, of course, only one at a time. You may laugh and say which seller is so stupid. In fact, if your bookstore only has two or three customers a day, you can do this :. If you map a bookstore to a table in the database and each book corresponds to a record in the table, you can apply "exclusive access" to the database table. Once a table is exclusive, other users cannot access the table unless the exclusive table

requirements: Define the software functions that developers must implement so that users can complete their tasks to meet business needs. (2) non-functional requirements: the non-functional requirements supplemented by functional requirements describe the behaviors and operations performed by the system to users. Including the details, performance, and quality attributes of the external interface. (3) Constraints on the design and construction of software products by developers and standards, s

At present, mobile application development is in full swing, such as Android and iOS applications. Developers are faced with the challenge of familiarizing themselves with the technical knowledge of the platform they use when developing wireless applications based on different operating platforms. Therefore, there are many cross-mobile development frameworks based on the HTML 5 standard. Developers only need to master the development skills of HTML 5,

independent function functions. However, some functions are employed by other sub-functions and are not level 1 sub-functions. For example, a recursion is usually written into two parts, one for initiating recursion and one for recursion. In a language similar to a non-nested function, the initiating recursion is converted into a function, and the recursion process acts as a function again, the two functions are parallel. In languages that

verification and data unbinding logic. (3) create a series of independent SQL statements for the modification of multi-row data. Like those generated when the update method is called in a sqldataadapter, these updates can be submitted independently or in batches to the server. However, although multiple statements are contained in batch submission, these statements are executed independently on the server. (4) use the BCP utility or the sqlbulkcopy object to load multiple rows of data into a ta
