摘要： System and methods are provided whereby screen write operations, such as common in data processing, are performed at a frequency matched to a user's ability to perceive such information. Specifically, screen writing operations are minimized to only those which are really necessary for perception by the user. In all other instances (i.e., time periods when updating is not needed), image information is written to rapid-access memory. At periodic intervals, the system is interrupted so that a display image (maintained in video memory) is updated from the image stored in the rapid-access memory. A screen device (CRT) coupled to the video memory is updated accordingly (upon the next scan of video memory). By maintaining image data locally, the penalty incurred with frequent, large data transfers to video or display memory is avoided.

摘要： A system of the present invention includes a server connected to one or more workstations or "clients" through a computer network. Methods are provided whereby network data access operations, such as are common in shared data processing, are minimized to only those which are necessary for system operation. In all other instances (i.e., time periods when updating is not needed), a workstation may gain access to the data from a local copy stored in a local buffer, preferably a rapid-access memory of the client. At periodic intervals, a workstation is interrupted for marking its local copy of the data as "invalid"--that is, the copy may be inconsistent with a corresponding version stored on the server. With the next access to the data, the local copy is updated from the version resident on the server. Additional optimization may be added for determining whether the server version has been "touched" (i.e., changed) since last transferred to the local buffer, with the local copy being updated only when such a change has been detected. By maintaining data locally, the penalty incurred with frequent, large data transfers across a network connection is avoided.
摘要翻译：本发明的系统包括通过计算机网络连接到一个或多个工作站或“客户机”的服务器。提供了将共享数据处理中常见的网络数据访问操作最小化到系统操作所需的方法的方法。在所有其他情况下（即，不需要更新的时间段），工作站可以从存储在本地缓冲器中的本地副本（优选地是客户端的快速访问存储器）获得对数据的访问。以周期性间隔，工作站被中断，将其本地数据副本标记为“无效”，即副本可能与存储在服务器上的对应版本不一致。随着对数据的下一次访问，本地副本将从驻留在服务器上的版本进行更新。可以添加额外的优化，用于确定自从上次传送到本地缓冲区以来服务器版本是否已被“触摸”（即改变），只有在已经检测到这样的改变时本地副本被更新。通过本地维护数据，避免了通过网络连接频繁的大数据传输造成的损失。

摘要： Development system with visual designer tools (Designers) are described for generating and modifying program code. During system operation, a user employs the Designers to visually create an application program and generate a source file. Moreover, the user can proceed to edit the file with a text editor and then return to the Designers to edit the form visually. Each Designer is a bi-directional or "two-way" tool: the user can modify a form either visually with a Designer, or by editing the generated code in a source (text) file with a text editor. The user can use both techniques interchangeably--switching at will. All changes which occur in Designers are reflected in the generated code and vice versa.
摘要翻译：描述了具有视觉设计工具（设计师）的开发系统，用于生成和修改程序代码。在系统操作期间，用户使用“设计者”可视化创建应用程序并生成源文件。此外，用户可以继续使用文本编辑器编辑文件，然后返回设计师以视觉编辑表单。每个Designer都是双向或“双向”工具：用户可以使用Designer直观修改表单，也可以使用文本编辑器在源（文本）文件中编辑生成的代码。用户可以互换使用这两种技术 - 随意切换。在设计师中发生的所有更改都反映在生成的代码中，反之亦然。

摘要： A client/server system providing methods of utilizing information stored locally on a client even after the client has modified data on the server is described. A client stores data from the server in a local "read-only" buffer(s), to speed up access to the data and reduce network traffic. Since the buffer is treated as a "read only" buffer, no locks are taken out at the server by the client. Accesses to particular data records are satisfied by looking first to the local buffer or cache. The client may proceed to modify the data records and commit changes back to the server. Moreover, the client updates or "writes through" the "read-only" buffer(s) with the changes so that the local buffer remains valid. The methods of updating data stored locally on the client provide significant performance increases as the client does not have to refresh data from the server.
摘要翻译：描述了客户机/服务器系统，其提供了即使在客户端在服务器上修改了数据之后也利用存储在客户端上的信息的方法。客户端将数据从服务器存储在本地“只读”缓冲区中，以加速对数据的访问并减少网络流量。由于缓冲区被视为“只读”缓冲区，因此客户端不会在服务器上取出锁。首先查看本地缓冲区或缓存来满足对特定数据记录的访问。客户端可以继续修改数据记录并将更改提交给服务器。此外，客户端更新或“通过”写入“只读”缓冲区与更改，以使本地缓冲区保持有效。当客户端不必从服务器刷新数据时，更新在客户端本地存储的数据的方法提供显着的性能提升。
