needs not only the subtlety of code, but also the rationality of database design. To satisfy an infinite class of classifications, the database needs to have two required fields, Id,pid. The ID is used to identify itself, and the PID is used to indicate the parent ID. That is, each classification record not only describes itself, but also describes another ID that is most closely related to it. Seemingly complex things are solved by such a small skill.

Experimental topicsWith the development of the Forum, the administrator found that the water king did not, but the statistical results show that there are three posts a lot of ID. According to the statistics of their posts more than 1/4, you can quickly find them from the list of posts?Experimental ideasJust like the last time, only the counter is changed from one to three, the definition array represents them, because according to statistics their number of posts more than 1/4, each bucket ID c
IMAX tickets will be queued when Avatar is about to go offline. After reading this, I was quite disappointed. The entertainment level of the film is far from that of iron Xia.
My thoughts are as follows:
1. Aliens are too good at Imitating Black indigenous peoples. I feel like a bunch of black people are changing to blue and adding a tail.
2. The plot is disappointing. On the surface, it was the victory of the Navy, but it was actually the victory

more complex objects through a page--in the era of the. NET 1.x--was a torment for us. Obviously a lot of objects have data row characteristics, why not direct access? So many people---including me, tried various methods. I was a loser of 5555, and a lot of people have succeeded in working out some very effective methods. But the situation did not last long--since the release of ODS from. NET 2.0, the shadow of my failure will never come back.

these engineering practices is the real-time question. Although I lack the development or use experience of the hadoop system, I do not think it hinders my understanding of this paper. In my mind, HDFS is GFS and hbase is bigtable. There may be differences in their implementation, but the main idea should be the same. If you are familiar with the two articles GFS and bigtable, this article can be regarded as "advanced" for GFS and bigtable ".1. application scenarios and requirements

. This is what many vendors once talked about. The two methods can be used flexibly based on different needs. Most db software uses row-based storage, and column-based storage features efficient single-column value compression. When selecting fewer columns, the io requirement is very low and the speed is fast, however, the compression efficiency of Row-store databases is also rapidly improved. Most of the requirements are to select row data for observation. Row-store also makes it easier for the
In bw3.5, an infosource can be assign multiple datasource, which are directly connected through the transfer rules operator. The relationship between them is 1: N.The same infosource can have multiple data targets. For example, two different ODS can allocate the same infosource. They are connected through the update rules protocol.In the same way, the same data target can also have multiple different infosources with N: N relationships.
