Under the traditional model, enterprises to establish a set of IT systems not only need to buy hardware and other
infrastructure, but also to buy software licenses, the need for specialized staff maintenance. The scale of the enterprise
will continue to upgrade the various hardware and software facilities to meet the needs. For enterprises, computers and
other hardware and software itself is not what they really need, they are just to complete the work, to provide effi cient
tools only. For individuals, we usually use the computer to install a lot of software, and many software is a fee, the
user is not often used to buy the software is very uneconomical. We only need to pay a small amount of 'rent' to 'rent'
to these software services for us to save a lot of money to buy hardware and software. Just as we use electricity every
day, but we are not every self-generator, it is provided by the power plant; we use tap water every day, but we do not
have every well, it is provided by the water plant. This model is great enough to save resources and facilitate our lives.
The face of the computer to bring us the troubles, we can like the use of water and ele

In today's world, there are several most authoritative international academic conferences in the fi eld of databases,
such as vldb, sigmod, and icde, which provide a platform for discussion and exchange of database researchers,
developers and applications, Guide and promote the development of database disciplines. We can see the hotspots of
today’s database technology and discover the future trends of related topics from the researchers at these conferences.
First, we analyzed the vldb and sigmod conferences in 2008, 2009 and 2010 accepted the core database technology on
the paper. We also cite the 'Observation on Database Research Trends via Publication Statistics' for statistics on these
two meetings from 1997 to 2006. We classify the paper into 28 classes, of which 22 are based on traditional database
techniques and the other six classes are new categories that we added during the analysis. Then, we predicted that six
new categories will be popular and become a new hotspot in the future, which is a major feature of this article. Finally,
we analyze the trend of database technology hotspots in recent years, and deduce the development trend of future
database technology.

3D technology has been widely used in the fields of architecture, medical image, cultural relic protection, film
production and 3D game. The polygon mesh is the most commonly used method for expressing the 3D model, it
connects the points on the surface of the 3D model into polygons as a unit, which can express complex surfaces and
provide strong adaptability. Especially in the use of triangular mesh the most widely used. But the triangular grid
display, simplifi ed, progressive transmission algorithm is not suitable for large-scale data sets. The triangular mesh data
fi le described in this paper with the boundary ball data fi le conversion system will represent and gradually compress
these triangular meshes. This representation is not only compact, but also can be quickly calculated, its biggest feature
is the high compression ratio, saving a lot of time and space, which makes it suitable for large-scale data sets. Its
execution program can serve large-scale 3D data processing projects. This article has demonstrated that this system can
be converted to include a large order of magnitude polygon model.

Cloud computing is a new Internet application model. The ultimate goal is to provide computing, services and
applications as a public facilities to the public, so that people can easily use the computer resources, while cloud
computing as a new IT implementation of the way, is a profound impact on the development and transformation of IT.
Cloud computing can provide enterprises with enterprise management key software, eff ectively reduce IT hardware and
software costs and maintenance costs, to adapt to the needs of enterprises in diff erent stages of development. But also
to help small and medium enterprises to make it less IT investment, access to more professional, more comprehensive
IT solutions. With the rapid development of information industry, all walks of life have to speed up the information,
the pace of digital, regional medical and health industry is no exception. China has long been concerned about the
medical and health industry information construction, the new medical reform program is the release of the domestic
regional medical information construction to a climax. Cloud computing as a cutting-edge technology of today's global
IT, its technology and philosophy to change the traditional computing resources application model, is to bring great
changes in enterprise IT applications, it is particularly important in the role of regional medical information, with a
very large Signifi cance. In this paper, the application of cloud computing in medical fi eld has been studied, and the
development situation of cloud computing in medical fi eld at home and abroad is analyzed in detail. The new situation
and the new situation of regional medical and health cloud will be put forward and forecast the development of cloud
computing in medical fi eld prospect. In addition, we summarize the advantages of cloud computing to regional health
systems, identify problems that exist in the development, present the risks and challenges it may bring, and put forward
countermeasures against these problems and risks.

With the development of computer technology and network communication technology and multimedia technology,
database technology has become an important technical means and software technology for organizing and managing
large amount of data in information society. It is the foundation of network information management system. It
not only has a complete theoretical basis, and with the rapid development of hardware technology and software
technology, its application is more and more widely. However, the rapid development of information technology is
that people face such a situation: CAD / CAM, CIMS, CASE, GIS and other applications require the management
of increasingly complex information, such as multimedia data, such as multimedia data, spatial data, scientifi c data,
Data and other data types, these data compared with the traditional type, not only the type of complex, diverse forms,
and storage, transmission, operation and retrieval methods also have many new features, new requirements, on the
one hand, the need for database technology and database systems To manage these complex data in order to obtain
the database system has many of the data management functions, such as query, retrieval, recovery, concurrency
control, integrity, storage management. On the other hand, due to the vigorous development of network technology,
information processing has long been from a single user environment to the development of the network environment,
this environment for resources, information sharing provides a great convenience, and because of multi-machine work
together to greatly improve the work , The combination of the two requires that the database management system be
able to manage complex data objects in a networked environment or heterogeneous environment. Traditional DBMSs
cannot eff ectively handle complex multimedia data, thus requiring the use of new multimedia indexing and retrieval
techniques. Multimedia database technology is an important part of computer technology, it can simultaneously acquire,
process, edit, store and display text, sound, video, graphics and other diff erent media, while it has diversity, integration
and interactivity and so on. Only to solve the key technical issues of multimedia, can be widely used to promote its
faster development.
