Label:I. 58 design ideas of database architecture in the same city(1) Usability design Solution: Copy + redundancy Side effects: Replication + redundancy will definitely cause consistency issues Guaranteed "read" Highly available method: Copy from library, redundant data, such as Problems: Master-Slave inconsistency Solution: See below A general approach to "write" High Availability: Dual-master mode, that

For a system with massive data volumes, the performance bottleneck will eventually fall on the database. At this time, hardware upgrades and program optimization are powerless, A simple query may also impose a heavy burden on the database. Grid computing divides a problem that requires a huge amount of computing power into many small parts, and then assigns these small parts to many computers for processing

Some time ago, I wrote 《Ripple: When the generic method meets the abstract class-my "Memory Database" birthnotes", Recorded the design process of the PDF. Net memory database, and made some minor changes recently. It has been put into production and is currently running well. I looked at the source code again today and thought it was necessary to draw a structural diagram of the memory

During database operations, we often need to read the architecture information from the database. I used to use SQL statements. This is convenient for incomplete information. Many of them need to guess by themselves or use sqlserver's event tracker to track and see how sqlserver Manager works. In. net. The dbconnection object has a getschema method, which is ver

In order to apply the scalability of the system, often need to scale out the database design, scale out design is to increase the database processing node to improve the overall processing capacity of the system, that is, increase the number of database servers to share the pressure. In this way the scalability of the system is enhanced, the cost is reduced, but

use similar ORM frameworks such as EntityFramework, NHibernate, and so on, because of the need to isolate concerns, improve code reusability and coding efficiency, and reduce programmer knowledge dependency on SQL. In fact, in the ORM framework, to achieve the database read and write separation, and our early use of ADO directly to implement this function is the same principle. The main difference, however, is that the ORM framework generally provide
