Design of universal data Rights Management System (i) Author: Yat-yun Preface: This paper provides a solution to integrate functional permissions and data permissions to meet the centralized control of rights management in multi-level organizations. This method is a further extension and extension of RBAC (role-based access control), that is, to increase the management of data rights on the basis of func

relationship, use inheritance to consider more, because modern language is a single inheritance (only one Class), multi-implementation (can implement multiple interfaces) of the use of, once the inheritance relationship from the class is used, Extensibility is actually limited to the range of the base class. But once you're sure you need it, put aside your concerns and use it directly. In fact, in all of the previous examples, we are inseparable from inheritance in almost every case.Combined us

Article Description: This thinking about e-book design stems from a recent experience and discussion of usage. Accustomed to the Kindle Physics key flip-screen reading, the Kindle touch of the screen operation is very unaccustomed (contact evoked), or even startled! Do not like E-books, in addition to not be free to write painting, the bigger problem is that e-books can not give the same experience as tradi

From design to implementation, we will teach you how to implement Android-Universal-ImageLoader-sequence and androidimageloader step by step. Indicate the source for reprinting. This article is from the blog of chaossss. Android-Universal-ImageLoader Github address Introduction: during this period, I have consolidated the basic knowledge of Java, learned

The following article mainly introduces the design overview of implementing inter-session warnings in the IBM DB2 general database. In some cases, do you want to migrate your database from the Oracle database to IBM?®DB2®Universal Database™? Do you think a special feature of Oracle may be lost? DB2 UDB is such a flexible database that can meet many of your needs. In this article, I will introduce how to imp

In the following sections, we can see the application of Messaging.DatabaseOpenStack components need to maintain their own state information. For example, Nova has a virtual machine in the specification, state, and this information is maintained in the database.

Http://blog.csdn.net/huomm/archive/2008/03/22/2205564.aspx I often encounter the problem of multi-condition joint query. I used to think that it is very simple. I always design the layout from the beginning.CodeOften, it takes a long time to query the surface, and the effect is not bad. Some time ago, I made a relatively general multi-condition dynamic query surface, which is quite convenient to reuse. I will provide a reference for you.Source fil

AUI thread processing. So why choose a double-ended queue, and why choose Lifolinkedblockingdeque as the default option?The double-ended queue is selected. Because Threadpoolexecutor is using the producer-consumer model, using Blockingqueue as the task processing queue within the Threadpoolexecutor class satisfies the requirements of the producer-consumer model for the task storage data structure. and in our assist. Lifolinkedblockingdeque is a subclass of Linkedblockingdeque. And Linkedblockin

Recently encountered the allocation and management of permissions, the need to design a separate set of structures. In fact, there used to be a lot of this design and blog, in the garden to look for it will find the results of n pages. Here also dare not say is a new idea, right when is their own summary and leave a footprint, easy to find. GM has two concepts here: 1, in order to attract attention See

Since this focusing part is very light, there'll be is very little dynamical errors in the system, which'll enable High measurement speeds.Most of the vibrations that remain'll be measured and can thus is corrected for, which'll be further explained in the Dynamic analysis of the Section 6.5.To the above metrology loop design, the beam delivery path and beam shielding f
