Construction, Migration, Deployment,and Publishing of Internet-Oriented
Scalable Web Software Systems in Non-Programming Mode
draft-yangcan-core-web-software-built-in-cloud-04
Abstract
This draft mainly focuses on the scalable architecture and publishing
protocol standard of REST-based SAAS cloud model Web software in non-
programming mode, stipulates the data structure pattern and data
exchange protocol for the construction and release of REST-based
scalable Web cloud service software systems. Using the standardized
framework and protocol, users can easily and quickly design their own
software systems in the cloud, transfer and release data, which may
make conventional software development so ease to improve the
efficiency of complex database construction and server management.
Without having to write codes under the standard framework, users can
get consistent style background to create service, rapidly develop
web application systems with the function of standard data management
and data maintenance, and directly publish the software system to the
end users of the Internet for access and use. And provide RESTful
APIs to facilitate external access to required service resources.
The framework can thus greatly shorten the software development life
cycle, and save a great deal of development cost and maintenance
overhead.

1. Introduction
With the rise of the Internet (especially the mobile Internet),
Internet-oriented Web services become the mainstream of software
architecture in the information age, but sophisticated web database
construction and system management bring great increase of cost of
software development, operation and maintenance. Whenever a system
needs to be upgraded or updated, a large amount of coding workload is
inevitable. With the rapid development of cloud computing and the
growing popularity of SAAS, more and more users intend to migrate
their software systems and deploy them to the cloud to get the cloud
service resources they need. At the same time, there exists a common
abstract model in the web information system, the system takes data
management and maintenance as the core content, we can therefore
extract its common features and provide a series of standards and
requirements for the flexible construction and agile release of web
software. In conclusion, cloud-oriented software migration and
deployment technology has very important theoretical and practical
significance. This draft focuses on the implementation standard of a
cloud-oriented software migration and deployment technology, through
which users can generate their own software system and migrate and
Yang, et al. Expires May 24, 2021 [Page 3]
Internet-Draft Web Software Built in Cloud November 2020
deploy to the cloud by simple operation. At the same time, it also
provides an open RESTful API for users to obtain the required service
resources through requests.From the development point of view, this
kind of technology can transfer and deploy the software system
conveniently and quickly, subtract the tedious and large number of
coding work, and avoid repeated development. From the perspective of
use, the convenient operation of this technology reduces the learning
cost of users, has a strong usability, and has a unified front-end
style. Users can access their own proprietary software system
through the Internet, which is easy to promote.It also provides a
expressive RESTful API that gives users the flexibility to adapt to
complex and changing needs.
2. Definitions and Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
The following definitions are for terms used in the context of this
document.
o "SAAS": SAAS is an abbreviation of Software-as-a-Service.It is a
model for providing software over the Internet. The manufacturer
deploys the application software on its own server, and customers
can purchase the required application services according to their
actual needs through the Internet, pay the cost to the
manufacturers according to the quantity of service and the length
of the order, and obtain the services provided by the
manufacturers through the Internet.
o "Cloud Computing": Cloud computing is a pay-per-use model that
provides available, convenient,on-demand network access, the user
enters a configurable computing resource sharing pool(resources
include network, server, storage, application software, services),
these resources can be provided quickly, with little
administrative effort or little interaction with service
providers.
o "Cloud Services": Cloud services are models of the addition, use,
and delivery of Internet-based related services, often involving
the provision of dynamically scalable and often virtualized
resources over the Internet.
o "Cloud Storage": Cloud storage is a network computer data storage
model. Data is stored on multiple virtual hosts and is generally
held by a third party rather than on a dedicated server.
Yang, et al. Expires May 24, 2021 [Page 4]
Internet-Draft Web Software Built in Cloud November 2020
o "Cloud Migration": Cloud migration refers to the migration of
enterprises from traditional platforms to cloud platforms.
Compared with traditional application platforms, cloud computing
platforms have the advantages of powerful computing power, storage
capacity, diverse services and high cost performance.
o "Software Migration": This draft is aimed at migrating existing
software systems that meet user requirements to a lightweight
information management software migration cloud service platform.
Systems migrated to the platform can be accessed over the
Internet.
o "Software Deployment": This draft is aimed at rapidly deploying a
new software system that meets user requirements on the
lightweight information management software migration cloud
service platform. The software system can be accessed through the
Internet.
o "Content Management": Using advanced information technology to
help users create, store, transmit, publish, apply and analyze
content, and use computer technology to evolve and extract it to
create more valuable content for enterprises and individuals.
o "NoSQL": Do not use SQL database. Such databases refer to other
types of databases other than traditional relational databases.
This type of database is more consistent and can handle very large
and high concurrent data. The techniques in this draft use NoSQL
to provide storage.
o "Distributed DataBase": It is a distributed file storage-based
database designed to provide a scalable, high-performance data
storage solution for web applications.
o "Web API": Web Application Programming Interface. An application
programming interface is an interface that allows users to access
information from another service and integrate the service into
its own application.
o "REST": Representational State Transfer. A software architecture
style,the service is abstracted into a set of discrete resources.
Through the HTTP protocol, different request methods(POST, DELETE,
PUT, GET) add, delete, modify, and query the resources specified
by the URI.
o "Restlet Framework": The Restlet project provides a lightweight
and comprehensive framework for "building a mapping between REST
concepts and Java classes". It can be used to implement any kind
of RESTful system, not just RESTful web services.
Yang, et al. Expires May 24, 2021 [Page 5]
Internet-Draft Web Software Built in Cloud November 2020
o "Multi-Tenant Technology": A software architecture technology,
whose key goal is to share the same system or program components
in a multi-user environment and to ensure logical isolation of
data between users.
o "Privilege Control": The permission control used in this draft
refers to adopting the role-based access control principle and the
group configuration permission template method to achieve the
separation of the authority control from the business logic.
o "Certification Security": Authentication security is part of the
security of the system. The authentication security system used
in this draft adopts the Cookie mechanism on the client side and
the Session mechanism on the server side, and uses the MD5 message
digest algorithm to achieve the authentication security of the
entire session.
o "Non-Programming Mode": Non-Programming Mode is defined as a kind
of software development mode in this draft, referring to develop a
software without any codes.
3. Technical Specific Implementation Standards
The main goal of this software migration deployment technology is to
help users quickly deploy a specific software system of their own on
a designated lightweight information management software development
and migration cloud service platform, or to migrate the user's
traditional software systems to the designated lightweight
information management software migration cloud service platform. We
propose an implementation standard for this technology so that users
who need it can use it for software development, migration, and
deployment.
Note: The cloud platforms described in the draft are all designated
lightweight information management software development and migration
cloud service platforms. The cloud platform administrator refers to
the administrator of the cloud service platform for the designated
lightweight information management software. The system
administrator is the administrator of the software system on the
cloud platform, also known as the tenant. The user is a normal user
under each software system, and is lower than the system
administrator level user.

Step (1) Requirements Submission: The user fills in the software
system requirements information in the software system
requirements table, and submits the request to GWDI through the
browser.
Step (2) Demand Acquisition: GWDI obtains the software system
requirements table submitted by the user, and reads the relevant
information related to the requirements in the software system
requirements table.
Step (3) Information Verification: GWDI analyzes and verifies the
relevant information about the system requirements obtained.
Step (4) System Generation: Automatically construct a Web software
system based on the verified requirements related information, and
inject the system into the cloud platform.

3.4.5. Steps of Principle of Constructing Web Software System
This method MUST satisfy the working principle of constructing Web
software system automatically according to the system demand table.
The principle includes the following steps:
1. The customer shall fill in the system requirements form
described in 3.4.1.1 according to the requirements.
2. The Web software framework obtains the system requirements table
uploaded by the customer in 1, and verifies whether the system
requirements table conforms to the verification standard. If it
does not conform to the verification standard, it prompts the
user to have the wrong format, please re-upload it.
3. The Web software framework reads the system administrator
information in the system requirements table.
4. Create a new system in the corresponding Web software framework
according to the information read in 3, in which the
administrator of the system is the system administrator in 3,
and the system name is the system name in 3.
5. The Web software framework determines whether there is any part
of user group information in the system requirements table. If
not, it jumps to 8; if there is, it goes 6.
6. The Web software framework reads information about user groups
in the system requirements table, including user group IDs.
7. According to the user group information read in 6, the user
group is generated in the system created in 4, and the relevant
information of the user group is the relevant information read
in 6.
8. The Web software framework determines whether there is any
relevant information about users in the system requirements
table. If there is no information about users, it will jump to
11; if there is, it will go to 9.
9. The Web software framework reads relevant information of users
in the system requirements table, including user ID, user name,
user password, and user group.
10. The Web software framework generates users in the system created
in 4 according to the user information read in 9, and the
relevant information of the users is the information read in 9.

Internet-Draft Web Software Built in Cloud November 2020
11. The Web software framework determines whether the relevant
information of the model part exists in the system requirements
table. If it does not, it will jump to 20, and if it does, it
will go to 12.
12. The Web software framework reads the number of models in the
system requirements table and assigns a current count of 0, then
go to 13.
13. The Web software framework reads the relevant information of the
model in the system requirements table, including the model
name, model entry person, model group ID, group permissions,
other user rights and other information.
14. According to the information related to the model read in 13,
the model is generated in the system created in 4. The model
name, model entry person, group ID of the model, group
permission and other user rights are the information read in 13.
15. The Web software framework determines whether there is any
information related to the structural fields in the model in the
system requirements table. If there is no information, it will
jump to 18; if there is, it will go to 16.
16. The Web software framework reads the relevant information of
structural fields in the model in the system requirements table,
including obtaining the name of structural fields of the model,
field types, whether to allow null identification, default
values and alternative values, etc.
17. The Web software framework creates model fields in the specified
model according to the relevant information of structural fields
in the model read in 16, and the field information is the
information read in 16.
18. Current model number +1.
19. The Web software framework determines whether the current count
is less than the number of models read in 12; if it is less
than, it will jump back to 13; if it is not less than, it will
go to 20.
20. The Web software framework generates the target Web software
system.

3.4.6. Steps of Injecting Data Records into Web Software System
The workflow of the Web software generation principle of this method
MUST include the workflow of automatically injecting data records
into the Web software system according to the data record exchange
table, including the following steps:
1. The customer shall fill in the data record exchange form as
required.
2. The Web software framework gets the data record exchange table
uploaded by the customer, and verifies whether the data record
exchange form meets the requirements of the data record exchange
form. If it does not meet the requirements, it prompts the user
to have the wrong format, please re-upload it.
3. The Web software framework reads the model field information in
the data record exchange table.
4. The Web software framework determines the required data exchange
model according to the model field information read in 3.
5. The Web software framework reads the data record information in
the data record exchange table line by line and injects it into
the model determined in 4 successively.
3.4.7. Submission of System Requirements Table
The submission of the system requirements table SHALL include:
1. Online submission: according to the Web form format provided by
the Web software generation framework, users fill in the system
requirements information online and submit it to the Web software
generation framework;
2. Offline submission: according to the offline form format template
agreed by the Web software generation framework, users fill in
the required software system demand information offline and
submit it to the Web software generation framework by file
upload.
3.4.8. Submission of Data Exchange Table
The submission of the data exchange table SHALL include:
1. Online submission: after the user constructs a new Web software
system according to the Web software generation framework, the
user enters data into the Web page through the newly generated

Internet-Draft Web Software Built in Cloud November 2020
Web software system, enters data information online and delivers
it to the generated software system;
2. Offline submission: after the user constructs a new Web software
system according to the Web software generation framework, the
user enters the data record information offline and submits it to
the generated software system through the data record exchange
table template format provided by the newly generated Web
software system by means of file upload.
3.5. Implementation Standards on Web Software Deployment
This framework MUST support the rapid deployment of a new set of
software systems that meet the requirements on the cloud platform,
where the deployment of software systems should support the
deployment of the following modules:
3.5.1. System Deployment
This framework SHOULD support two ways to deploy a system:
o Supports registering users' own systems through cloud platform
administrators to create system administrators belonging to users.
o Supports users to register their own system through cloud platform
and register their own system administrator.
3.5.2. Model Deployment
This framework SHOULD enable system administrator users to enter
their own software system and deploy the created models on the cloud
platform, where the created models are configured as follows:
o Model name, input personnel, and user group read and write
permission are necessary when the model is created.
o Field name, field type, whether the field is allowed to be empty,
field default value, and field alternative value in the model are
optional fields for creating the model.
3.5.3. User Deployment
This framework SHOULD support to create new users affiliated to the
software system created by a system administrator user on the cloud
platform, where the creation of users is configured with user ID,
user nickname, and user password.
Yang, et al. Expires May 24, 2021 [Page 21]
Internet-Draft Web Software Built in Cloud November 2020
3.5.4. User Group Deployment
This framework SHOULD support to create new users affiliated to the
software system created by a system administrator user on the cloud
platform, where the creation of user groups is configured as follows:
o The user group ID is necessary.
o It is optional to select many users into the user group, but one
user group must have one use at least.
3.6. Implementation Standards on Web Software Migration
This framework SHOULD support the migration of existing software
systems that meet the given requirements to the cloud platform, where
the migration of software systems should support the migration of the
following modules:
3.6.1. Model Migration
This framework SHOULD support the migration of the specified model
from the source system to the target software system, where the
source container of the model includes at least one of the following:
1. Relational Database
* SQLSERVER
* MYSQL
* ORACLE
2. Excel File. Here, the model migration may support two modes:
* Migrating data from source to specify model structure
* Migrating data from source to specify the model structure and
migrating data within the model
3.6.2. User Migration
This framework SHOULD support the migration of users in the source
system and their access rights to the target software system, where
the user's source container includes at least one of the following:
1. Relational Database
* SQLSERVER
Yang, et al. Expires May 24, 2021 [Page 22]
Internet-Draft Web Software Built in Cloud November 2020
* MYSQL
* ORACLE
2. Excel File
3.6.3. User Group Migration
This framework SHOULD support the migration of user groups in the
source system and their access rights to the target software system,
where the user group's source container includes at least one of the
following:
1. Relational Database
* SQLSERVER
* MYSQL
* ORACLE
2. Excel File
3.6.4. User Group Deployment
This framework SHOULD enable system administrator users to enter
their own software systems and create user groups on the cloud
platform, where the creation of user groups is configured as follows:
1. A user group ID created for identifying the user group is of
necessity.
2. It is optional to select many users into a user group, but one
user group must have one use at least.
4. Security Considerations
This draft proposes an implementation standard for software migration
deployment technology for cloud environments, and does not make
special requirements for the security of the technology itself.
However, the security of the cloud platform and the security between
different users in the software system are required. The security of
the cloud platform is mainly authentication security, and can also be
considered as session security to ensure the security of the user
during using software. The security of different users in the system
is called permission control. Data isolation between different
systems, different user groups in the same system, and different
resource access rights between different users should be considered.
