In my opinion, the following factors are indispensable:
Multiple Tabs
Because there are many menus, the tree on the right must be considered. If there are still many menus, the top should be considered.
In the future, add more.

Recently feel that the speed of the project is a bit slow, I am in the network of a search, sent a good thing, can not help to share with you, I hope you could try, there is room for improvement! Requires removal of white space, extraction of common code, reduced page.Mr. Fat searched and found the trimfilter. It can be implemented to remove white space, code collation, the size of the page reduced to the original 1/2[no actual test], the finishing speed is good, the usage is very simple.My men

The logical model is not required throughout the step, and can be generated directly from the conceptual model.The physical model relies on a specific physical implementation, using the database object, the original "entity-relationship" converted to "table-foreign Key", the attribute of the entity is converted to the table column, and the data type of each column is converted to the data type supported in the corresponding DBMS.for

bits of data through the Mosi line and reads the 1 bits of data from the machine through the line;2) The slave sends 1-bit data through the miso line, and the host reads the 1-bit data through the line.This is achieved through a shift register. As shown in 2, there is a shift register between the host and slave, and the two are connected into a ring. With the clock pulse, the data is moved out of the host register and Slave register in order from high to low, and then to the slave register and

3. Summary
From the multi-sample mode, we can see that the singleton mode is actually a special case. In the code, we use the "Hungry Chinese" method to implement instantiation. When using the multi-sample mode, we should pay attention to the same things as the singleton mode. Attention should be paid in Di

2. Notes
After mastering the previous articles (overview, multimedia manager, multimedia connector, and multimedia server) about OMCS, we can perform secondary development based on OMCS. Next we will introduce the development steps from the server and client perspectives.1. Server Development
Aside from the specific business logic, OMCS server development is quite simple. The procedure is as follows:
