Entity Framework 4.1/4.3 (DBContext 3 state tracking) 　　Let's talk about DBContext. This time the content will be consistent with the content mentioned in DBContext 2. 2. add, delete, and modify objects in DBContext (Adding, Changing, and Deleting Entities) In DBContext 2, we talked about "add, delete, and modify", in which we already talked about "add, delete, and modify ". Some of the content is not mentioned. Let's complete it. (1) Find The "Find or Add" Pattern) Scenario: We often add a r

the following methods for deserializing an object:Public final Object ReadObject () throws IOException, classnotfoundexceptionThe method takes the next object out of the stream and deserializes the object. It has a return value of object, so you need to convert it to the appropriate data type.To demonstrate how serialization works in Java, I'll use the employee class mentioned in the previous tutorial, assuming we define the following employee class, which imple

deserializing an object. Public final object readobject () throws ioexception, classnotfoundexception This method retrieves the next object stream and deserializes it. The returned value belongs to the object type, so you need to convert it to the appropriate data type. Let's take a look at an example. Here I will not translate it, but it will be displayed in English: To demonstrate how serialization works in Java, I am going to useEmployee class that we discussed early on in the book. Suppo

Oracle transparent data encryption (TDE) real-world use analysis, oracletde Since the R2 version of Oracle Database 1Og, a feature called TDE makes data encryption extremely easy. All we need to do is to declare a column as encrypted, and the rest is done by Oracle. When a user inputs data, the column value is intercepted and encrypted, and then saved in the encrypted format. Then, when this column is queried, the column value is automatically decrypted, And the decrypted text (plaintext) is ret

ObjectInputStream class contains the following methods for deserializing objects: Public Final throws IOException, classnotfoundexceptionThis method retrieves the next object outside the stream and deserializes it. The return value is an object, so it needs to be converted to the correct data type.To demonstrate how serialization works in Java, use the previous employee class. Assume that you have the following employee classes that implement serializable: public class Employee implements

Label:The previous study notes on Indexeddb mainly wrote the basic operation of INDEXEDDB database-adding and deleting; but why should we use INDEXEDDB? Why has indexeddb been favored by developers? The main thing is the core features of INDEXEDDB: With cursors and indexes and scopes to really play INDEXEDDB power1. Index: Why is it called INDEXEDDB? Because it gives us the index to query the value we need;2. Cursors: Cursors provide us with the data that we iterate over,3, the scope: and the cu

identification. The header of each large data block must have SI. In this way, when they reach the target end, it can be correctly put into its stream, where SI is a 16-digit number starting from 0. 2.3 stream serial number when a large data block reaches the target SCTP, it is passed to the appropriate stream and arranged according to the original sequence. In addition to SI, SCTP also uses stream sequence number (SSN) to define each data block in e

attributes in public, feather-level, and shared accessories. This type of configuration allows customers to use properties without referencing unwanted accessories. Which accessories will recognize attributes? If there is no module read attribute, it will be worthless. You may put the class that reads the attribute in the same assembly where the attribute resides. However, as mentioned above, you want to put the methods and attributes for reading attributes in different accessories. Public stri
