摘要： One embodiment of the present invention provides a system for establishing multiple sessions between a database and a middle-tier client. During operation, the system receives a request for a plurality of sessions at a database from a middle-tier client. In response to the request, the system authenticates the middle-tier client, and creates a session between the database and the middle-tier client. The system clones the session one or more times to create the plurality of sessions. Finally, the system sends a plurality of session-handles associated with the plurality of sessions to the middle-tier client. This enables the middle-tier client to distribute the session-handles to end-user clients in response to subsequent requests from the end-user clients to access the database.
摘要翻译：本发明的一个实施例提供了一种用于在数据库和中间层客户端之间建立多个会话的系统。在操作期间，系统从中间层客户端在数据库处接收对多个会话的请求。响应请求，系统对中间层客户端进行身份验证，并在数据库和中间层客户端之间创建会话。系统克隆会话一次或多次以创建多个会话。最后，系统将与多个会话相关联的多个会话句柄发送到中间层客户端。这使得中间层客户端可以将会话句柄分发给最终用户客户端，以响应最终用户客户端访问数据库的后续请求。

摘要： One embodiment of the present invention provides a system that facilitates distributed processing of database operations. During operation, the system receives a database operation at a distributed command processor, wherein the database operation includes a query language command. Next, the system performs a set of non-data processing operations associated with the database operation to obtain a set of non-data processing results. The system then sends the query language command to a database, which enables the database to execute the query language command to obtain a result.

摘要： Systems, methodologies, and other embodiments associated with providing multi-layered security for configuration items are described. One exemplary system may include a security logic configured to process the contents of a configuration item based on the source of the configuration item and the integrity of the configuration item. The exemplary system may also include a verification logic configured to further process the contents and to selectively provide the contents. A configuration item may be provided to the security logic by a configuration item provider known to the security logic and related to the security logic by a first set of keys. The security logic may be related to the verification logic by a second set of keys different from the first set of keys.

摘要： One embodiment of the present invention provides a system that accommodates different types of verifiers in a computer system. During operation, the system receives a username and a password. The system then computes a verifier based on the password. If the size of the verifier exceeds a storage limit, the system transforms the verifier into a transformed verifier which conforms to the storage limit, thereby allowing the computer system to compare the transformed verifier with a locally stored verifier associated with the username to facilitate user authentication.

摘要： One embodiment of the present invention provides a system for masking index values in a database. During operation, the system receives a request to mask a column in a database, wherein the column is an index-column. Next, the system retrieves a tree which is used to index the column, wherein the tree provides a sorted representation of values in the column. The system then locates the root-node of the tree. Then, for each child-node in the tree, the system determines if the child-node is a leaf-node. If so, the system masks a node-value for the leaf-node without resorting the tree. If not, the system leaves the node-value unmasked.

摘要： One embodiment of the present invention provides a system for automatically classifying data in a database. During operation, the system receives and executes a database operation. Next, the system automatically determines if any data was modified as a result of executing the database operation. If so, for each data item that was modified, the system automatically determines if the data item is associated with a classification-rule. If so, the system automatically reclassifies the data item according to the classification-rule. If not, the system leaves a classification of the data item unchanged.

摘要： A method, computer-readable storage medium, and an apparatus are provided to facilitate authorizing a user during a database transaction. The method starts by receiving a request at the database to perform a database operation. Upon receiving the request, the database sends an authorization request to an authorization module to determine if the user has authorization to perform the database operation. In addition, the database continues executing the database operation without waiting for completion of the authorization request. Next, the database receives a response from the authorization module. The database then checks the response to determine if the user has authorization to perform the database operation. If so, the database commits the database operation, and if not, the database rolls back the database operation.

摘要： One embodiment of the present invention provides a system that protects data from unauthorized modification in a table, wherein the table contains one or more rows, and wherein each row contains one or more columns. During operation, the system chooses in a row one or more columns to be protected. The system then produces an encrypted value for the row based on the data stored in the chosen columns. Next, the system stores the encrypted value in a column which cannot be easily modified. In this way, a later-produced encrypted value generated from the values in the protected columns can be compared against the previously stored encrypted value to verify the integrity of the data stored in the protected columns.

摘要： One embodiment of the present invention provides a system that facilitates using query signatures to provide security for a database system. During operation, the database system receives a query. Next, the system parses the query to determine a signature for the query. This signature specifies a structure based on operators for the query and is independent of the value of literals in the query. The system then determines if the signature can be found in a signature cache which contains valid query signatures. If so, the system processes the query.
