摘要： In one general aspect, a computer system can include instructions stored on a non-transitory computer-readable storage medium. The computer system can include a logging table generator configured to generate a logging table corresponding with an original table targeted for an upgrade, and a control table generator configured to generate a control table configured to store a version identifier for changes logged in the logging table. The computer system can include a change recorder configured to receive an indicator of a change to a record of the original table during execution of at least a portion of the upgrade of the original table, and a key recorder configured to store in the logging table a primary key identifying the record of the original table and the version identifier stored in the control table.

摘要： Techniques for optimizing a software application include receiving, at a local computing system, a query from an application for data stored on a database table, the query including a context defined by a name of the database table; comparing the context of the query to a context of a predefined query scenario; based on the context of the query matching the context of the predefined query scenario, retrieving data stored on a secondary database replicated from data stored on a main database; and passing the retrieved data from the secondary database to the application.

摘要： According to some embodiments, a programming language in an application server may access different database server implementations, wherein the programming language accesses content of database tables via work areas derived from the database tables. A database table may be mapped to a work area such that each column in the database table is mapped to a corresponding component of the work area (having a default component type based on the column type of the associated column). It may be determined that a particular column in the database table is to store large object data content, and a new mapping to a work area may be defined such that a particular column maps to a corresponding component having a component type other than the default component type.

摘要： A system and method for synchronizing distributed table buffers is disclosed. A node may contain a synch manager and a table buffer having a synch identifier. The synch manager may use the synch identifier to coordinate updates to the table buffer. The updates to the table buffer may be performed in an asynchronous and/or a synchronous manner.

摘要： In an embodiment, a database interface performs a three-step optimistic database access. The database interface initially performs an optimistic read of a database object. The database object is checked for consistency after the optimistic read. If the database object is inconsistent, a first pessimistic read is performed with an isolation level that does not guarantee consistency (e.g., with an isolation level of committed read). The database object is checked again for consistency after the first pessimistic read. If the database object is inconsistent, a second pessimistic read is performed with an isolation level that may guarantee consistency (e.g., with an isolation level of repeatable read).
摘要翻译： 在一个实施例中，数据库接口执行三步乐观的数据库访问。 数据库接口最初执行数据库对象的乐观读取。 数据库对象在乐观阅读后进行一致性检查。 如果数据库对象不一致，则使用不保证一致性的隔离级别（例如，具有提交读取的隔离级别）执行第一次悲观读取。 在第一次悲观读取之后，再次检查数据库对象的一致性。 如果数据库对象不一致，则使用可以保证一致性（例如，具有可重复读取的隔离级别）的隔离级别执行第二悲观读取。
