Digital libraries are related to huge scaled static data archives. Numerous huge digital libraries, for example, national libraries and information centers have been worked for the long haul information protection. To attain information, the cell phones have been giving extraordinary comfort to the moving person. Many persons need to move between better places for work and business, and they frequently need to attain information through phone communication along their moving. They regularly need to seek and get information from digital libraries and search engine always. So it has been more critical for advancing the improvement of research about how to give better digital library services in the portable computing. However, the digital library services in the portable computing condition have numerous constraints. Current mobile hosts connected to the digital libraries still have the following problems which are frequently disconnections, bandwidth is still narrow, memory and storage are limited, screen size is small and the input and interaction on mobile devices are still not convenient compared with the static hosts with keyboard and mouse.
As stated by Sun Y., Zhu L., Zhang J., and Qiao, X. (2014) mobile agent is an important part of the mobile computing system. A mobile operating system, named Agent Tcl, is explained including the outline and execution. It supports the mobile PCs and separated operation. It features network-sensing devices and a docking system that enables an operator to directly move between mobile PCs, regardless of whether it is associated with the system.
As the authors mentioned, mobile computing is a ripe territory of work for researchers in the territories of database and data administration. The inherent impediments of mobile computing systems show a summons to the conventional issues of database administration.
Cloud computing has changed the methods for administration and information stockpiling of the applications. Cloud computing has been viewed as a definitive answer for broadening battery lifetimes of mobile systems.

Current digital library information benefits in the mobile computing incorporate the accompanying styles which are one is short message service(SMS)- based information service and the other is wireless application protocol (WAP)- based information service. The handling techniques for various questions are additionally unique.
The constant query is prepared instantly by the digital library server and the short answer information comes back to the portable host. Errands that need a long time, for example, download and suggestion of digital library are exchanged to the individual cloud space or users email in the deferred query style.
As indicated by the distinctive prerequisites of reaction time, the digital library servers could assign the information service line and ?nish the query errands ef?ciently. Cache in the digital library server side and pre-fetch in portable host side could enhance the information service quality to defeat the constraints of mobile communication. The mobile host can pre-fetch the informative information when a user is browsing since the transmission capacity of a portable system is low.
In this paper, we propose a synergetic system for digital library services in the cloud and mobile computing condition. It consolidates the digital library servers, portable hosts, and individual cloud space into a synergetic work assemble flawlessly. The proposed component can help advancing the learning sharing and enhance the work ef?ciency by accelerating the data exchanging between digital library and users by diminishing the in?uences of constraints of little storage spaces and information exchanging under the Internet associations.
