A strongly typed dataset can help us quickly build the data access layer, and its simplicity allows us to use it extensively in small projects. But it also has some minor flaws, and here is a discussion of what the flaws are and how we can avoid them. 1 in a query, it only supports operations on this table and does not support operations on multiple tables. In this case, we can write a stored procedure ourselves and create a new TableAdapter so that it will help us generate a new logical entity

in machine learning, we often encounter unbalanced datasets. In cancer data sets, for example, the number of cancer samples may be far less than the number of non-cancer samples, and in the bank's credit data set, the number of customers on schedule may be much larger than the number of customers who defaulted. For example, a very well-known German credit data set, the positive and negative sample classification is not very balanced: If you do not do

with SQL statements and stored with a specified name, then to call the database to provide the same functionality as a defined stored procedure, just call execute to automatically complete the commandAdvantages of stored procedures:1. Stored procedures are compiled only at creation time, and each subsequent execution of the stored procedure does not need to be recompiled, while the general SQL statements are compiled once per execution, so the stored procedure is usedCan improve database execut

To write cross-browser CSS, you must know the two modes for the browser to parse CSS: standard mode and quirks mode ). The so-called standard mode means that browsers are parsed and executed according to W3C standards.CodeThe weird mode is to use the browser's own method to parse and execute code, because different browsers do not parse and execute code in different ways, so we call it the weird mode. The

1. Basic Concepts A DataSet is an off-line cache-storing data that, like a database, has a hierarchy of tables, rows, columns, and also includes constraints and associations between data defined for a dataset. The user can pass. NET Framework's namespace (NameSpace) to create and manipulate datasets. Users can understand the concept of a dataset through the composition of these standards, such as attributes (properties), Collections (collections).

Question: nyoj 1070 weird elevator [I] This question comes from the OJ 1206 dormitory's elevator of Xiangtan University. It was the question of the competition at that time. I did not read the question clearly, Analysis: This is actually a simple one-dimensional DP, using DP [I] to represent the minimum physical strength required from the first layer to the second layer. Because you cannot stay in the adjacent floor, so you can transfer from DP [I-2

Link: Ultraviolet A 11983-weird Advertisement Given n rectangles, I would like to ask how many areas are covered more than K times. Solution: divide each rectangle into two line segments, one for adding overwrite value 1, the other for reducing overwrite value 1, and record the height (abscissa) of the two segments at the same time ). Create a line segment tree for discretization of the ordinate coordinates, and sort the line segments by height. Maint
