ppi in teradata

　　A small partner who wants to study in the field of mobile web, the first thing to pass is the relationship between the logical pixels and the device pixels.First into the mobile web, must understand a few units (DPI, PPI, DP, PX detailed calculation method and the source of the algorithm?) ）： Dip (DP): device independent pixels (devices independent pixels), is an Android development unit, 1DP indicates the 1px length at a screen point densi

database such as Oracle, Sybase, SQL Server, Informix and IBM DB2, etc.), have some discounts on performance, but openness is better. In addition, the CA's OLAP server is currently integrated only with Microsoft's IIS Web server. The 6.NCR teradatancr Teradata is the most powerful competitor in the high-end data warehousing market, running mainly on the UNIX operating system platform of NCR Worldmark SMP

According to the author's experience in the Data Warehouse ETL internship in Teradata and Main Street network, we can understand the relationship and difference between them in architecture design. Teradata is generally the enterprise-class data Warehouse, in the Teradata Data Warehouse architecture, generally is buffer layer, model layer, market layer. As shown

Label:At present, Teradata Data Warehouse ETL operation using ELT mode, because the loading is too heavy, the need to transfer the ETL pressure to a dedicated ETL server. For ETL tools, there are already mature commercial/open source tools in the market, such as Informatica's PowerCenter, IBM DataStage, and open source kettle.Here are some of my own thoughts, the starting point is, how to spend a relatively small price to switch the ELT mode to ETL mo

flexibility. WinCC is a good choice for single-user systems and redundant multi-server/multi-user systems. Through ActiveX, OPC, SQL and other standard interfaces, wincc can easily communicate with other software. WinCC and S7-200 series PLC communication, can use one of the two communication protocols of PPI and Profibus. 1. Implementation of communication between WinCC and S7-200 PLC through PROFIBUS Protocol (1) software and hardware requirements:

Players need to use the gyroscope of the device to control the ball to avoid obstacles and finally reach the destination. You can modify game parameters to customize the content.Step 2: Target Development Platform First, we nee

-security systems and connect to IRQ ); In a multi-core system, interruptions are allocated to different processors; Set the level trigger or edge trigger mode (not equal to the peripheral trigger mode ); Virtualization extension; The arm cpu has only two external connections, one is IRQ and the other is FIQ. The corresponding processing modes are generally IRQ and FIQ respectively) processing mode. Therefore, at last, the GIC needs to integrate the interrupted sink into two lines to connect to

more pixels the screen has, the finer the picture is.The higher the resolution, the more information is displayed in the unit area, and the more content we can see.Screen scaleThe screen scale is the ratio of the width to the height of the screen, and today more refers to the ratio of resolution, i.e.Screen scale = screen landscape Resolution/Screen portrait resolutionIn addition, there are some relatively common ratios between various devices and platforms, and we recommend that you use the re

The official mobile phone screen resolution ratio is the physical pixel ratio, such as ipone5 device resolution of 640*1136DP, the screen is 4 inches.1. Calculate PPIThe PPI, or pixels per inch, represents the number of pixels (Pixel) owned per inch. Therefore, the higher the PPI value, which means that the display can display the image at higher density. Of course, the higher the density of the display, th

Tutorial description: Tool used: Corona SDK Execution difficulty: normal Operation Time: one hour Step 1: Application Overview Using the prepared image materials, we will compile our own compass Application Based on Lua and Corona SDK APIs. Basically, the final product is similar to Apple's own official compass app in iOS.Step 2: Target Development Platform First, we need to select the operating platform that the application works rely on. After confirming this, we can select the image

Being Retina display does not depend only on the PPI. It also depends on the viewing distance. Using the formula A = 2tan-1 (H/2d) at 15 inches (2.54 cm) away qualifies for a retina display. The eyes cannot discern the pixels at the distance, which is the essence of retina display. How is retina's screen defined? Why is the resolution of a new iPad screen called a Retina screen. Next, let's have a deeper understanding. Why did Steve propose

example, 480x800 's screen is made up of 800 rows and 480 columns of pixels. Each point emits a different color of light that forms the picture we see. The physical size of the phone screen is not proportional to the pixel size. The most typical example of the IPhone 3GS screen pixel is the 320x480,iphone 4s screen pixel is 640x960. Just twice times, but two phones are 3.5 inches.So, we're going to introduce one of the most important concepts: pixel density, which is the

The 3-generation Kindle Paperwhite compared to 2 generations, raising the screen pixel density from the original 212 PPI to the PPI, which boosted the screen pixels by a factor. The memory is upgraded from the previous generation of 256MB RAM to the MB RAM. In addition, the 3-generation Kindle Paperwhite fuselage has not been upgraded, still 4GB.
