IT outsourcing research has often been at the transaction level, focusing on the role of the characteristics of the IT activities as the antecedents of outsourcing decisions.
      
The formalism is applied to a system level design methodology, where design decisions are used to gradually transform the functional specification model of the system to a transaction level model with components and communication structure.
      
In particular, error simulation are considered in the perspective of the transaction level modelling (TLM) capabilities of this emerging system level design language to obtain a coherent, environment for functional verification.

Replication is one of the key techniques in promoting the performance of mobile database systems. A lot of research has been focused on mobile database replication recently, and many models and algorithms have been proposed. However, most of the work does not focus on the conflict reconciliation problem. Some approaches that do focus on the conflict resolution require specialized knowledge of the system for all transactions and special concurrency control models, which limits their adaptability. Besides, some proposed methods do not ensure transaction serialize ability, which can cause serious consistency problems in many circumstances. In order to solve these problems, a new mobile database replication scheme, Transaction Level Result Set Propagation (TLRSP) model, is put forward in this paper. The conflict detection and resolution strategy of TLRSP model is discussed in detail, and the implementation algorithm is proposed. In TLRSP model, mobile users are allowed to access local replicas of the database and locally commit mobile transactions when the system is disconnected. The locally committed transactions are sent to the fixed database server for conflict reconciliation and result set incorporation when the system is reconnected. In order to ensure database consistency, transactions locally committed at mobile hosts need to be validated at the database server before they can be globally committed. Therefore, mobile transactions that have executed conflicting operations will be aborted, and only those mobile transactions that do not violate the consistency of the database system can be globally committed. TLRSP model uses an incremental refresh method, and only recently updated data need to be transmitted during the synchronization process. Besides, by utilizing a simplified log structure and by introducing version number and access control into the system, TLRSP model reduces the resource consumption and communication costs. To sum up, through an efficient conflict reconciliation and result set propagation strategy, TLRSP model provides a flexible and effective solution to the replication problem of mobile database systems.

Synchronization is one of the key technologies in maintaining the consistency of replicated mobile database systems. A lot of research has been focused on transactional synchronization schemes in recent years and many models and algorithms have been proposed. However, existing transactional synchronization schemes have some limitations. In order to solve these problems, a new synchronization scheme, double-timestamp transaction-level synchronization (DTSTLS) model, is put forward in this paper. DTSTLS model utilizes a three-tire architecture. Therefore existing database products can be used as its database server, which improves the flexibility and extensibility of the system. As an asynchronous group replication method, DTSTLS model allows mobile users to access local replicas of the database and to locally submit mobile transactions when the system is disconnected. The locally committed transactions are sent to the synchronization server for conflict reconciliation and synchronization when the system is reconnected. Mobile transactions that have executed conflicting operations will be aborted, and only those mobile transactions that do not violate the consistency of the database system can be globally committed. In this way, the consistency of the database system is ensured. Besides, through a novel timestamp strategy, DTSTLS model cuts down the resource consumption and reduces the communication costs. Detailed simulation experiments are carried out, and the results show that the proposed methodology not only ensures the serializability and consistency of the mobile database system, but also reduces storage consumption and communication cost.

同步处理技术是保持复制的移动数据库系统一致性的一项关键技术,但现有的事务级同步处理算法存在着一定的局限性.为了克服这些缺陷,并增强其实用性,提出了一种新的移动数据库同步处理模型──基于双时间印的事务级同步(DTSTLS)模型.DTSTLS模型采用了一种三级复制体系结构,系统可以直接使用通用的数据库产品作为其数据库服务器,因此具有良好的可扩充性.作为一种异步的多主副本复制方法,DTSTLS模型允许移动计算机在断连的情况下存取本地副本,从而造成系统短暂的不一致,重新连接时进行冲突检测及同步处理,使系统重新收敛于一致性的状态.此外,通过一种独特的时间印处理策略,DTSTLS模型减少了通信代价,并降低了资源消耗.实验结果表明,DTSTLS模型提高了移动数据库系统的资源利用效率,保证了事务调度的可串行性和数据库的一致性.

System-level performance analysis plays an increasingly important role in the development of SOC. According to the similarity between Virtual Prototyping Machine and FPGA system, a methodology for system-level performance analysis based on hardware/software co-verification is presented. A virtual monitor and control unit (VMCU) is designed, and embedded into the prototype of the system. During the simulation, VMCU monitors the status of hardware components, and according to the access protocol, acquires transaction-level events of hardware. In RTOS, device file for VMCU is installed, so that VMCU can collect transaction-level events of software. All the data is sent to external Database and tools through the communication link. Database is used to store the large quantity of data from simulation. By manipulating tables in database, as much information as possible can be extracted. This hierarchical structure makes this methodology highly portable and able to evaluate the system performance efficiently with low overhead and high correctness.

随着系统集成芯片(SOC)的发展,系统级性能评估在系统的开发中发挥了越来越重要的作用。本文基于两种常用系统软硬件协同验证方法(FPGA和虚拟原型机)抽象结构的一致性,提出了一种新的系统性能评估方法。该性能评估方法通过在系统硬件原型中嵌入虚拟监视设备VMCU,并利用它和操作系统配合获取操作系统和应用程序仿真数据,同时监视硬件的仿真事件,并通过通信链路将数据传递给数据库,由外部工具对数据进行分析、处理,将性能评估的结果可视化。该性能评估方法具有低过载、可移植性强、直观高效、评估结果准确性高的特点,从而有效地促进了系统的开发与优化。
