Error:Problem Solving Process:1, first determine the CPU architecture2, this is a 64-bit architecture of the CPU, if the use of ELF parameters, the default is in 32-bit mode to deal with, then need more precise to specify this mode, such as ELF32 (32-bit), ELF64 (64-bit), the specific reference: http://www.nasm.us/doc/ Nasmdoc7.htmlThen rewrite the above can be as follows:Nasm-f elf64-g-F stabs sandbox.asm-o sandbox. old-o sandbox.

1. Oracle's overall architecture is divided into three parts
The first part: System Global Area (SGA)
Part Two: program Global zone and background process
Part III: Oracle's Files
2. From functional angle to those division

Includes: Control files, data files, and log files

layer, because the last layer does not have the next layer), but does not know the other lower layer. For example, a cake factory only needs to know how to extract flour, cream, and eggs from a flour mill, cream mill, and Egg Factory, you don't have to worry about how the flour and the cream come from.
It can be said that the division of labor in line with the above two points is the ideological source of the layered architecture. The following is
Analysis of. NET logic layered architecture, analysis of. net Architecture
I. Basic Knowledge preparation:
1. layer principles:
(1) Each layer is called by the upper layer in interface mode.(2) The upper layer can only call the lower layer.(3) Dependency can be divided into loose interaction and strict interaction.
2. Business Logic classification:
(1) application logic.(2) domain logic.
3. layer used
in the Agile development , we did find a framework that would enable domain experts, architects, to work together to design an adaptable ROA architecture. But I think we should think of it from another angle. ...even domain experts and architects can work together in a team, but after all, domain experts and architects are people, not gods. So, in the end, how much of the future needs change can be predicted from the current version ? This is really
by Vikas Singh on SepIn 3-layer architecture
3-layer architecture separates the application into 3 components which consists of Presentation layer business layer and D ATA Access Layer.
In 3-layer architecture, user interacts with the Presentation layer.
3-layer is a linear architecture.

Write in front From the beginning to write code to now, has done several projects, BS and CS have, has always been a code of farming. However, as a progressive programmer, there is an ideal to become an architect. So, in peacetime work, but also actively to see a variety of books, see the Garden inside the fine article. Hope, in this pursuit of the dream of the road, can leave little bit, also is a kind of consolidation of knowledge, some share.Reading experience Soon after work, I read the fi
The previous article introduces the basic architecture diagram of Spring Cloud cloud service architecture, this article constructs the code according to the architecture diagram, according to the micro-service design idea, unifies the spring cloud own service discovery, the governance, the disposition management, the distributed and so on the project outstanding
multiple servers is formed by means of routing differentiation;Iv. Extensibility-A new business is on the line(1) Measurement criteria: Is it possible to achieve transparency without impact on existing products when new business is added (does it need to be modified to match existing business?) );(2) Main means:① Event-Driven architecture: Using message Queue implementation;② Distributed services: separating business and reusable services;V. Security
Design objectives:
-(Hardware failure is normal, not accidental) automatic rapid detection to deal with hardware errors
-Streaming Access data (data batch processing)
-Transfer calculation is more cost-effective than moving the data itself (reducing data transfer)
-Simple data consistency model (one write, multiple read file access model)
-Heterogeneous Platform portability
HDFS Architecture
Adopt Master-slaver Mode:
Namenode Central Server (Master)
. This is where the activity as a global controller is linked to the presenter view.
Using fragment is more advantageous to the layout of a tablet computer or a multiple view screen.
Summarize
The use of MVP architecture shows that the responsibilities between the various levels are more single and clear, but also to a large extent reduce the coupling of the code. For the official MVP
Three-tier architecture, three-tier architecture and mvc difference01. What is a three-tier architecture?
01. user Interface layer: receives User input, presents the output to the User, verifies access security, and is responsible for the correctness, validity, and presentation style of the input data, however, we are not responsible for the correctness of the ou
clearly, we can name the three projects (Class Libraries added in the solution) as follows ):
Business logic layer: BLL. The namespace is set to BLL by default.
DataAccessLayer: DAL. The namespace is set to DAL by default.
SQL help class: SQLHelper. The namespace is set to SQLHelper by default.
In addition, we usually add another class library to facilitate data transmission. This class library runs through the entire three-tier architecture. Entity
