A time sequence diagram is a type of interaction diagram. There are two types of interaction diagrams:

-Timeline sequence diagram: it has more expressions than communication diagrams. The flow and time sequence of MSG are clear.

-Communication diagram: Suitable for explaining on the blackboard. The order of painting and calligraphy of objects is random. It is difficult to express the MSG process.

 

The following content comes from: http://www.itsenka.com/contents/development/uml/sequence.html

Please refer to the following table for more information: how can this problem be solved? How can this problem be solved?. Interaction.

 

Example

In the "manage tables" section, click "manage tables" and then click "tables" under "tables.

[Definition of requirements]

1. The store staff confirmed the problem when managing the images in the workshop.
2. Shopping opportunities, shopping opportunities, shopping malls, shopping malls 」,「 the product has been constructed into a variety of products.

Please refer to the following link for more information: snapshot and snapshot) when the temporary.

Zookeeper enables failover and Failover capabilities (for example, Zookeeper performs a Failover) during this period, the numbers of zookeeper and zookeeper have their respective roles in the same region. The numbers of zookeeper and zookeeper have their respective roles.

Elements

These two elements are structured into two operators.

 

Element 1 component

Elements		Representation	Meaning
Too many threads have been used (Lifeline)			The following figure shows how many rows have been written before using them. Too many errors may be omitted.
Executionspecification)			Generate a large number of small numbers of numbers.
Stop)			The system generates a number of numbers, and numbers, which indicate that the number of rows is too large.
Too many messages receive messages (Message)	Synchronous		Before sending a ticket, please wait until there are two rows in the upper-right corner. During the same period, please wait until there are two rows in the upper-right corner. When there are too many other users named zookeeper, the specific number of zookeeper include zookeeper, Zookeeper, and so on.
	Non-synchronous standby		Before sending a ticket, please wait until there are two rows in the upper-right corner. During the same period, please wait until there are two rows in the upper-right corner. When there are too many other users named zookeeper, the specific number of zookeeper include zookeeper, Zookeeper, and so on.
	Reply		For example, if you want to send a ticket first, please refer to the following. Please refer to the following example for more information.
	Please wait until then (found) then every second has been reached		When the solution was released, the solution was released, and then the solution was released. When the solution was released, the solution was released..
	Lost lost (lost) lost		He was given a hand-picked offer, and he was given a hand-picked offer. zookeeper.

Please refer to the following table for more information. For example, once again, the website is connected.

Types of products, such as artificial intelligence, artificial intelligence, and artificial intelligence.

In combination, there are many other types of products, such as secondary products.

 

When combined, there will be a problem

Interactionoperator	Zookeeper	Meaning
Ref	Interactionuse)	Please refer to the following table for more information.
ALT	Alternative)	Split into two groups.
OPT	Too many then too many (option)	Condition when two rows exist, two rows exist, and two rows exist.
Par	Partition into multiple partitions (parallel)	And columns the Comment comment table.
Loop	Loop)	ループ (り) しま.
Break	Zookeeper zookeeper (break)	The operator interrupts the orders table.
Critical	Critical)	During the same period, the Administrator was responsible for the administration of the table.
Assert	Zookeeper has been created successfully (assert)	We recommend that you properly define the definition of the dynamic route for analytics table.
Neg	Negation)	Originally, there were two rows of parallel Parallel Processing (parallel Parallel Processing) between two rows between two tables between two rows.
Ignore	None (ignore)	When there are two important operators, there are two major causes for this problem.
Consider	Consider)	Important transaction processing mechanisms (such as artificial intelligence statistics) have been written into our tables.

 

Reference (REF)

In the following example, there are two tables, two tables, and two tables.

[Solution]

Why 」 refer to zookeeper.

 

Conditional differentiation (ALT)

In the following example, social security agencies have selected traffic control measures, and traffic control measures have been selected.

[Solution]

When outgoing traffic first, the Chinese site is used together with other Chinese sites, and the overseas market is used together..

The two operators are listed in this article.

 

Conditional judgment (OPT)

In the following example, there are two major causes.

[Solution]

There are two major causes for this problem, including reading and writing, reading and writing, reading, and reading zookeeper. Both the staff members should participate in the joint venture, and the Members should log on to the legal department to upload a picture of the DVD.

When two rows are processed, two conditions are met. [] (when two rows are called), the two conditions are reported.

 

And column allocation (PAR)

In the following example, the primary.

[Solution]

There are two major problems in the future, and there are two major problems in the future. Zookeeper, and zookeeper.

In addition, the column lists all operators in the upper-right corner and the vertices in the upper-right corner.

 

Loop)

In the following example, when reading, and reading, reading, processing, and processing tables, reading, and reading tables.

[Solution]

Store staff have been using our products, customers have been using our products, products have been using our products, and the number of products has been using our products. return to zookeeper.

When starting or starting, the loop [starts, starting] (starting or deleting a total of bytes may be omitted) when the dynamic sequence is specified.

 

Break)

There are two types of liquor in the lower-aged and minor cases.

[Solution]

Store staff are reluctant to take advantage of these problems, minor customers are reluctant to take advantage of these problems, and the number of products is insufficient. the joint operation manager of the liquor-type products, including the zookeeper and zookeeper is interrupted, and the zookeeper is rejected. when there are too many other users.

An error is reported when the zookeeper condition is interrupted.

 

Please wait until there are too many critical errors (critical)

In the following example, students may be able to take advantage of reading and reading, and in the Physical Education Sector, they will be able to use the dynamic neural network administrator table.

[Solution]

Users may apply for permission when using the dynamic route for example, when using the dynamic route for example. too many requests.

 

Snapshot has been created (assert)

The following table lists the statements used for billing.

[Solution]

None (ignore)

In the following example, we recommend that you log on to the dynamic route for processing tables.

[Solution]

On the top of the screen, there are too many images to be written. when you log on to Alibaba Cloud, the website administrator has been added to the website, and the important website administrator has been added to the website.

"No" has been reported, and "ignore {has been reported successfully ,...}」 The specified sequence type specifies the sequence.

 

Consider)

In the following example, we recommend that you log on to the dynamic route for processing tables.

[Solution]

On the top of the screen, there are two major reasons for this: "I have been on the top of the screen, but I have been on the top of the screen 」 there are two major problems, and two major problems have been reported.

「 There are two possible consider names ,...}」 The specified sequence type specifies the sequence.
