1. Stateless value: Stateless servers can handle many users with very few objects. The more users in idle state, the more useful the stateless servers are. 2. Session state: Relevance: Session state is only related to the current session. It exists in business transactions and is separate from other sessions and their business transactions. The […]

1. The temptation of distribution objects: Object distribution in middleware is very useful for transparent upper layer, but cross-process, cross-machine (and network) calls affect performance! 2. Remote and local interfaces: 1) Objects accessed remotely need to use coarse-grained interfaces, while objects accessed locally need fine-grained interfaces (local connections can provide coarse-grained objects when optimizing performance) […]

Consider three aspects of technology practice: continuous integration, driving test development and refactoring 1. Start at the domain level 1) Transaction script mode is the simplest, suitable for building on relational database; domain model needs very professional technology, as well as the connection of fish database; table module mode compromise, environment with very powerful recordset […]

1. Transaction scripts 1) Call the database: Transaction scripts compose all logic into a single process in which the database is invoked directly or only through a simple database store. 2) script processing: Each transaction has its own transaction script, although common subtasks between transactions can be decomposed into multiple subroutines. 3) Operating mechanism: A. […]

1. Table data entry Acting as an object for database table access entry, an instance handles all rows in the table. 1) Operating mechanism: Table data entry contains all the SQL used to access a single table or attempt, such as selection, insertion, update, deletion, etc. Other code calls its methods to implement all interactions […]

1. Unit of Work It is used to maintain the list of objects affected by business transactions and coordinate the write of changes and the resolution of concurrency problems. As follows: 1) Operating mechanism: Key: It’s the submission that decides what to do. It opens a transaction, does all concurrent checks (using pessimistic or optimistic […]

1. Model choices: 1) Domain logic complexity: 2) Choice: When the domain logic complexity is low, choose the thing script. If the development environment has a large number of recordset-based tools (. Net and VS), you can choose the table module. When the development team is experienced, choose the domain model. The three models […]

One of the most important reasons for the success of relational database is the existence of SQL, which is the standard language for database communication. 1. Architectural pattern: How to drive domain logic to access data: SQL statements are embedded in programming languages. Line data entry, table data entry: Separating SQL access from domain logic […]
