PC-Lint generates an alarm for this situation. There are t

We have explained in detail the core data framework and the design classes. Next we will explain an example of using these classes by writing code completely manually. This example is from the official example of apple.
Someone may ask why I want to use EF to create a data table that loves you. What are the benefits of code first?
When using EF to create a database or table, you only need to design a simple C # class. When the table content changes, it automatically updates the database structure and retains the original data.
EF is very powerful. It supports primary and Foreign keys and can generate the same data type as in dB. Since these two tables are simple, I w

3. Explicitly submit things after all data inserts have been completed. Once committed, SQLite automatically reverts the current connection to autocommit mode.The following is the implementation step of the sample code:
1). Create a test data table.2. Manually open a thing by executing the BEGIN TRANSACTION statement.3. Prepare the INSERT statement and related binding variables.4. Inserts data in

only for threading, when designing the data table of the transaction (transactional transaction in a sense is also the embodiment of the synchronization mechanism), you can think of a table as a need to synchronize the array, if the operation of the table data too much can consider the transaction separation (which is why to avoid large tables), such as the data for the field splitting, Level sub-table, etc.Third, the source code interpretationAs can
