The entire system uses over stored procedures and over scalar functions similar to stored procedures. Alone1998, a netizen, said: "pure SOA does not advocate the use of stored procedures/functions, and the database is only considered as a place to store data. All business logic is not implemented in the

The final decision depends on the following two conflicting goals: Get the data from the data source to the final destination as quickly as you couldAbility to recover without starting from scratch when an error occurs in the processing process The strategy for data aggregation varies greatly depending on the environment and business requirements. If you plan to handle all ETL data processing in memory, do not forget that any kind of data warehouse, re

the responsibility is still a little unclear, in the Order.addorder (OrderField OrderField) method, There is the product logic inside if (product. Price , of course, here is the business logic is relatively simple case, if the business is more complex, there will be a lot of code in the Order class, in the end, we will find that we have no way of the business architecture is the use of the model to design.
(image servers) and database servers (data servers) through background applications. Now, I think you should understand (1) Why the background applications directly access the business logic layer, while the store applications need to access the business logic layer through the service layer, as the data access volume increases, we can deploy the service on multiple servers as required to relieve the access pressure, without increasing the access vol

If the application system architecture design Simonw@2005.4.24 is reproduced, please indicate the source. On the surface, we are developing a variety of different applications. In fact, the corresponding architecture design is relatively stable. Programming in a good architecture
dependencies are all entangled in the business logic layer. How to decouple dependencies is a task left to designers apart from implementing business logic. Let's talk about some other things here for everybody to entertain. In his book "enterprise application architecture model", Martin Fowler summarized the architecture model of the domain layer (namely the business logic layer). He divided the busin
, therefore, the optimization of MySQL is not about the database itself, but about the architecture design, that is, how to rationally allocate access pressure to the database through technologies such as table sharding, database sharding, replication, and Cache. How to
Let's take a look at our technologies and briefly talk about the technical architecture design of some large websites. Technologies and tools involved: Java, springmvc, ibatis, freemarker, MySQL, mongdb, memcached, ehcache, and Maven. It is impossible for a website to design a perfect architecture that can take into
addition, using the slow query log in MySQL itself: Slow-log can also record SQL statements that take a lot of time in the query, so as to optimize and rewrite the corresponding statements.In addition, on the MySQL terminal, the show processlist command can effectively view the threads currently running in MySQL, including the thread status, whether to lock the table, and so on. It can view the SQL Execution status in real time, optimize some lock table operations. Ii.
