当版主和当博士的秘诀看来差不多：就是剪刀＋浆糊。轻松吧？

！！小弟有几个疑问：

内存数据库调出数据是否会占用很大的内存？？

内存数据库是否需要定期释放内存？？

菜鸟顶一下，高人请解答！！～～～

急急急!!! 我的需求是6分钟就要向数据库中导入50多兆的记录，不过我用close和sq.clear不能很好地释放内存，请指教？？？

Description: Attend McObject’s free 1-hour webinar, “Embedded Databases: Building In ‘Always On’ High Availability”, for development solutions that address the “always on” needs of mission critical embedded systems, while also taming these applications’ growing data complexity.

When data management coding becomes a burden, integrating an off-the-shelf database management system (DBMS) can improve reliability, scalability and time-to-market. Embedded systems developers often choose in-memory database systems, which offer faster performance, greater efficiency and a smaller code footprint.

But this approach highlights the issue of operational continuity, important in so many embedded applications. How can a RAM database survive the failure of the software or hardware environment in which it operates? And how can an embedded database (in-memory, or not) meet the high availability (HA) needs of telecommunications, military/aerospace, industrial control and other applications that require fault-tolerance?

In this presentation, McObject CEO Steve Graves lays out specific strategies to overcome this vulnerability. Attendees will learn general principles of database High Availability, or the ability to keep an application or service continuously operational and usable by clients (99.999% uptime is the benchmark).

The presentation walks through the process of HA-enabling an application on both Master and Replica database nodes, as well as speeding development and preserving platform-independence by using an HA Application Framework. It addresses advanced topics such as synchronous (“eager”) vs. asynchronous (“lazy”) replication and the role of time-cognizance in deterministic HA applications.

In the event’s Q&A session, attendees can leverage Mr. Graves’ 20+ years of embedded database experience to address their own data management and High Availability challenges.

Learn to reap the benefits of High Availability in real-time embedded applications. Register to attend “Embedded Databases: Building In ‘Always On’ High Availability” on Friday, July 11!
