need to be a priority assessment factor. 8. The challenges of the new architecture are challenged by introducing a memory database as an intermediate persistence layer and then adding a distributed architecture to support massive data access. The first and most visible scenario is the complexity of the new architecture, just as the massive MySQL cluster architecture was born initially. We use H2, an open source High-performance memory database as an example to illustrate: 1 integration of Ameob

I am a newbie. I can only implement the functions simply. The following is a simple function of the development manual. I operate it according to it, and I will do it right away. In fact, development manuals are comprehensive. After researching the development manuals, you will not be asked questions about idiots, whi

I slept a lot today, so I started debugging with sate210 with VGA work control board tonight, because I saw that the P clock and parameter standards were not very high, so I thought, the maximum LCD pixel clock of s5pv210 is 166 m, so it fully meets the 1080 p 1920*1080 resolution requirements. So I filled in the parameters according to the standard and modified the related clock PARAMETERS OF THE sate210 wince system, O
