teradata database architecture

In order to expand the scalability of the application system, we often need to scale out the database. The scale out design increases the overall processing capability of the system by adding database processing nodes, that is, increase the number of database servers to share the pressure. In this way, the scalability of the system is enhanced, and the cost is re

the master database, saving master server resources and facilitating recovery. Disadvantage: the cost increases. Phase 8: Cluster(Double) +Dual storage + backup + replication +Dual-distribution + SSBAsynchronous solution: The main advantage of this method is to asynchronously process data streams to relieve the pressure of instantaneous high traffic on the master database. This solution is

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

Multi-to-many, database horizontal splitting architecture, multi-to-many splitting Repost the public account's article "the path to architect" In fact, I still don't understand some points after reading it. I will keep it for a while and then digest it slowly ~~ This article will take "friend Center" as an example to introduce "many-to-many" businesses. As the data volume increases, the

"Abstract" in this paper, a two-tier distributed database architecture is established by introducing the memory database layer. This scheme is used to solve the problem of data storage and access in massive and high concurrency systems, especially for the complex and complex Internet stations of electronic commerce and other data models. These years the Internet

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

The Sub-database table is The main means to solve the MySQL level expansion. There are many discussions about strategy, such as hash extension, expansion by time, extension by scope and so on. But the people who really want to implement the sub-list of the library often feel that " the strategy listens to the end of the light, aware of this matter to code ", so the main purpose of this article is to provide friends with an achievable

Oracle Database system is a complex software system. The Oracle architecture refers to the relationship between the components of the Oracle database management system and these components, including the memory structure, background process, physical and logical structure. Overall diagram of the Oracle Database System:

Previously, the company had been using petshop4.0 to streamline the architecture, but the amount of code is relatively large. If you want to change a method parameter, the interface layer, database layer, and logic layer must be closely associated with the change.But I cannot see the benefits of doing so. I can use the most common Layer 3 (Data + logic + representation). Why must I add an interface and a fa

Oracle architecture database structure oracle database consists of two parts: database and instance database: a series of physical files that specifically store data and related objects. Instance: refers to a series of operating system processes and the memory zone (SGA) it

We all know that the Oracle database system is a very complex software system. In fact, the Oracle architecture refers to the relationship between the components of the Oracle database management system and these components, including the memory structure, background process, physical and logical structure, etc. The Oracle

This occurs in another table during Database Import:Source architecture. Data Table Name In this case, we will see"[Table name] error indicating that the object does not exist"This problem is caused by the structure of the data table. Therefore, you need to modify the schema name of the data table to DBO, and change all the objects of the database that belong to
