The answer to this question is the term Data Dictionary. A Data Dictionary or also known as metadata repository is a set of information that is stored which contains data, meanings, and values. The data dictionary can be used as a tool for communication between the stakeholders.
Solution:
The process of transaction can guarantee the reliability of business applications. Locking resources is widely used in distributed transaction management (e.g; two phase commit, 2PC) to keep the system consistent. The locking mechanism, however, potentially results in various deadlocks. In service oriented architecture, the deadlock problem becomes even worse because multiple transactions try to lock shared resources in the unexpectable way due to the more randomicity of transaction requests, which has not been solved by existing research results. In this paper, we investigate how to prevent local deadlocks, caused by the resource competition among multiple sub-transactions of a gl obal transaction, and global deadlocks from the competition among different global transactions. We propose a replication based approach to avoid the local deadlocks, and a timestamp based approach to significantly mitigate the global deadlocks. A general algorithm is designed for both local and global deadlock prevention. The experimental results demonstrate the effectiveness and efficiency of our deadlock prevention approach. Further, it is also proved that our approach provides higher system performance than traditional resource allocation schemes.

<span>The answer is CTRL + A, this selects whole worksheet (A means all). In computing, a Control key is a transformer key which, when pushed in combination with one more key, achieves a singular operation (for example, Ctrl + A; like the Shift key, the Control key infrequently achieves any purpose when pushed by itself.</span>
