    Abstract: Techniques are provided for maintaining data persistently in one format, but making that data available to a database server in more than one format. For example, one of the formats in which the data is made available for query processing is based on the on-disk format, while another of the formats in which the data is made available for query processing is independent of the on-disk format. Data that is in the format that is independent of the disk format may be maintained exclusively in volatile memory to reduce the overhead associated with keeping the data in sync with the on-disk format copies of the data.

    Abstract translation: 提供的技术用于以一种格式持续保持数据，但使数据库可以以多种格式提供给数据库服务器。 例如，数据可用于查询处理的格式之一是基于磁盘格式，而数据可用于查询处理的另一种格式与磁盘格式无关。 独立于磁盘格式的格式的数据可以专门保存在易失性存储器中，以减少与保持数据与数据的磁盘格式副本同步的开销。

    Abstract: 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.

    Abstract translation: 本发明的一个实施例提供一种用于在数据库中自动分类数据的系统。 在运行期间，系统接收并执行数据库操作。 接下来，由于执行数据库操作，系统会自动确定是否修改了任何数据。 如果是，对于修改的每个数据项，系统自动确定数据项是否与分类规则相关联。 如果是这样，系统会根据分类规则自动重新分类数据项。 如果没有，系统会保留数据项的分类。

    Abstract: Techniques are provided for more efficiently using the bandwidth of the I/O path between a CPU and volatile memory during the performance of database operation. Relational data from a relational table is stored in volatile memory as column vectors, where each column vector contains values for a particular column of the table. A binary-comparable format may be used to represent each value within a column vector, regardless of the data type associated with the column. The column vectors may be compressed and/or encoded while in volatile memory, and decompressed/decoded on-the-fly within the CPU. Alternatively, the CPU may be designed to perform operations directly on the compressed and/or encoded column vector data. In addition, techniques are described that enable the CPU to perform vector processing operations on the column vector values.

    Abstract: A computer (200) modifies data inside an object (201 ) in a database (210) without modifying other data in the remainder of the object (201 ). Insertion of new data (208C) at a specified location in the object (201 ) does not require movement of existing data in the object (201 ). Instead, the computer (200) is programmed to insert new data at a physical end of the object (201 ), and modify metadata (230) based on the specified location. Similarly, deletion of existing data from a specified location in the object (201 ) is performed without movement of other data in the object (201 ), by updating the metadata (230). The computer (200) uses the metadata (230) when reading from the object (201 ), so that the new data (208C) is automatically read whenever the specified location is accessed. The computer (200) may optionally output a handle that is static, relative to other insertions and deletions, to identify specific data within the object (201 ), for use in building indexes on the object (201 ).

    Abstract translation: 计算机（200）修改数据库（210）中的对象（201）内的数据而不修改对象（201）的其余部分中的其他数据。 在对象（201）的指定位置插入新数据（208C）不需要移动对象（201）中的现有数据。 相反，计算机（200）被编程为在对象（201）的物理端插入新数据，并基于指定位置修改元数据（230）。 类似地，通过更新元数据（230），执行从对象（201）中的指定位置删除现有数据而不移动对象（201）中的其他数据。 当从对象（201）读取时，计算机（200）使用元数据（230），使得每当访问指定位置时自动读取新数据（208C）。 计算机（200）可以可选地输出相对于其他插入和删除是静态的句柄，以识别对象（201）内的特定数据，用于在对象（201）上构建索引。

    Abstract: Techniques are described for characterizing and summarizing seasonal patterns detected within a time series. According to an embodiment, a set of time series data is analyzed to identify a plurality of instances of a season, where each instance corresponds to a respective sub-period within the season. A first set of instances from the plurality of instances are associated with a particular class of seasonal pattern. After classifying the first set of instances, a second set of instances may remain unclassified or otherwise may not be associated with the particular class of seasonal pattern. Based on the first and second set of instances, a summary may be generated that identifies one or more stretches of time that are associated with the particular class of seasonal pattern. The one or more stretches of time may span at least one sub-period corresponding to at least one instance in the second set of instances.

    Abstract: A method, apparatus, and system for tracking row and object database activity into block level heatmaps is provided. Database activity including reads, writes, and creates can be tracked by a database management system at the finest possible level of granularity, or the row and object level. To efficiently record the tracked database activity, a two-part structure is described for writing the activity into heatmaps. A hierarchical in-memory component may use a dynamically allocated sparse pool of bitmap blocks. Periodically, the in-memory component is persisted to a stored representation component, sharable with multiple database instances, which may include consolidated last access times and/or a history of heatmap snapshots to reflect access over time. The heatmaps may then be externalized to database users and applications to provide and support a variety of features.

    Abstract: For automatic data placement of database data, a plurality of access-tracking data is maintained. The plurality of access-tracking data respectively corresponds to a plurality of data rows that are managed by a database server. While the database server is executing normally, it is automatically determined whether a data row, which is stored in first one or more data blocks, has been recently accessed based on the access-tracking data that corresponds to that data row. After determining that the data row has been recently accessed, the data row is automatically moved from the first one or more data blocks to one or more hot data blocks that are designated for storing those data rows, from the plurality of data rows, that have been recently accessed.

    Abstract translation: 对于数据库数据的自动数据放置，维持多个访问跟踪数据。 多个访问跟踪数据分别对应于由数据库服务器管理的多个数据行。 当数据库服务器正常执行时，根据与该数据行相对应的访问跟踪数据，自动确定是否最近访问存储在第一个一个或多个数据块中的数据行。 在确定最近访问了数据行之后，数据行被自动从第一个或多个数据块移动到指定用于存储来自多个数据行的那些数据行的一个或多个热数据块，这些数据行具有 最近被访问。
