scd type 1 and type 2 in informatica

Record type The record type is used to define a fixed set of different types of data items. Each element or field in the record has its own type. All domains are listed in the record type definition. Each domain corresponds to one domain name and can be accessed through the domain name. The following briefly lists the

Label:High performance MySQL reading notes chapter fourth--schema and data type optimization reading notes Good logical and physical design is the cornerstone of high performance, and the schema should be designed according to the query statement that the system will execute, which often requires a tradeoff between various factors. This chapter lays the groundwork for the next index optimization and query optimization, covering the theme of MySQL's un

Here we will transform the object at the beginning of everything to form our own type system to facilitate subsequent types implementation, recognition, and processing. Format conventions First, describe the format conventions: 1. Global constant definition: Start with '$', in uppercase. Var $ MY_CONST = "ABCDEFG "; 2. Global Function Definition: Start with '$'

1. Basic Data TypesNo memory allocation issues involved. It is divided into eight types: Byte, short, int, long, float, double, char, Boolean, respectively. The default values are as shown in the figure: 2. Reference data typeDevelopers are required to allocate space for them. It is divided into three kinds, namely array, class, interface. The default values are as shown in the figure: * * Personal sele

Can be used to assign null to data types such as Int,double,bool that cannot be directly assigned to NULL Define 2 variables such as this: int i; Default value of 0 int? II//default value NULL2. Used to determine whether the object is empty, if the object is empty, then regard

1. Notes on unsigned: 1.unsigned int can be abbreviated as unsigned 2. When using char type, char has 3 kinds of situations, Char, signed char, and unsigned char, and when we write char, the compiler will choose from signed Char and unsigned char. Signed char is -127 ~ 127, unsigned char is 0 ~ 255 3.

(e.g. bankname for a row, represents a CreditCard type) TPT Considerationseven Though this mapping strategy are deceptively simple, the experience shows that performance can be UN Acceptable for complex class hierarchies because queries always require a join across many tables. In addition, this mapping strategy are more difficult to implement by Hand-even Ad-hoc reporting are more complex. This is a important consideration if you plan to use

object is directly created, as follows:M_pfilterobject = new cfilterclass ();// Make the initial refcount 1 to match com CreationM_pfilterobject-> addref ();Because the base class of the filter implements the reference counting of objects, even in the second case, the operation on the created filter object can fully follow the com standard.Filter is an independent function module. It is recommended that you do not depend on other third-party DLL. Bec

In PHPArrayIt is actually an ordered ing. Ing isValuesAssociatedKeys. This type has been optimized in many aspects, so it can be considered as a real array, or a list (vector), a hash list (an implementation of ing), a dictionary, a set, stack, queue, and more possibilities. The value of an array element can also be another array. Tree Structure and multi-dimensional array are also allowed. AvailableArray ()Language Structure to create a newArray. It

First, IntroductionSorted Set each element in the collection is associated with a fraction, so the top n elements with the highest or lowest score can be obtained, and the fractional-related operations are obtained for the elements within the specified fractional range. Although each element in the collection is different, their scores can be the same. An ordered collection type is somewhat similar to a list type
