    • Embodiments of the present invention include in-memory processing for data warehouse applications. In one embodiment, data records from a data warehouse application are stored in a data storage structure of an in-memory database. Data received from the data warehouse may be stored in a queue and loaded into the data storage structure according to predefined rules. Stored data records are associated with in-memory database transactions that caused the stored data record to be stored, and may further be associated with transactions that caused the stored data records to be changed. A mapping is generated to associate requests from the data warehouse application with in-memory database transactions. The data warehouse application may retrieve data in a change data format calculated on-the-fly.
    • 本发明的实施例包括用于数据仓库应用的内存中处理。 在一个实施例中,来自数据仓库应用的数据记录被存储在存储器内数据库的数据存储结构中。 从数据仓库收到的数据可以存储在队列中,并根据预定义的规则加载到数据存储结构中。 存储的数据记录与导致存储的数据记录被存储的内存数据库事务相关联,并且还可以与导致存储的数据记录被改变的事务相关联。 生成映射以将来自数据仓库应用程序的请求与内存中数据库事务相关联。 数据仓库应用程序可以以实时计算的更改数据格式检索数据。

    • A request for at least a portion of a business object is received by a database from a client in a first half of a roundtrip between the client and the database. Each of the tables includes a primary key column and a plurality of records. The primary key column provides, for each record in the table, a primary key for one of a plurality of business objects. Thereafter, the database identifies records within a set of tables among a larger number of tables in the database by matching a primary key associated with the business object with the primary key in the primary key column. Once this identification has been made, the database obtains all values responsive to the request from the identified record and transmits, in a second half of the roundtrip between the client and the database, the obtained values for the business object to the client.
    • 在客户端和数据库之间的往返的前半部分,数据库从客户端接收对业务对象的至少一部分的请求。 每个表包括主键列和多个记录。 主键列为表中的每个记录提供了多个业务对象之一的主键。 此后,数据库通过将与业务对象相关联的主键与主键列中的主键进行匹配来识别数据库中较大数量的表中的一组表内的记录。 一旦进行了此识别,数据库就会根据来自所识别的记录的请求获取所有值,并在客户端和数据库之间的往返的后半部分中将所获得的业务对象的值发送给客户端。
