Character data types

Oracle allows you to define your own object data types, which you can use for creating objects, discussed in detail in Chapter 21, “Object Relational Interactions with Oracle.” Oracle also includes specialized data types for working with XML, spatial data, and media data, as well as ways to access type descriptions when the data type is not known.

The collection of built-in data types in a data base system (e.g. integer, floating point number, character string) and built-in operators (e.g. +, -, *, /) were motivated by the needs of business data processing applications. However, in many engineering applications this collection of types is not appropriate. For example, in a geographic application a user typically wants points, lines, line groups and polygons as basic data types and operators which include intersection, distance and containment.

This paper addresses two remaining challenges in Chinese word segmentation. The challenge in HLT is to find a robust segmentation method that requires no prior lexical knowledge and no extensive training to adapt to new types of data. The challenge in modelling human cognition and acquisition it to segment words efficiently without using knowledge of wordhood. We propose a radical method of word segmentation to meet both challenges.

Working with Your MySQL Database CHAPTER 9 225 Let’s look at a few of the more common uses of ALTER TABLE. One thing that comes up frequently is the realization that you haven’t made a particular column “big enough” for the data it has to hold. For example, in our Customers table, we have allowed names to be 30 characters long. After we start getting some data, we might notice that some of the names are too long and are being truncated. We can fix this by changing the data type of the column so that it is 45 characters long instead: alter table customers...

Functions make the basic query block more powerful and are used to manipulate data values. This is the first of two lessons that explore functions. You will focus on single row character, number, and date functions, as well as those functions that convert data from one type to another, for example, character data to numeric. At the end of this lesson, you should be able to
Explain the various types of functions available in SQL.
Identify the basic concepts of using functions.
Use a variety of character, number, and date functions in SELECT statements.

Most of the information that we include for each node and edge is straightforward to obtain from the Twitter stream. However, there are some data processing aspects that require special handling: Mapping user names to IDs: The Twitter stream relates the tweets with internal user identifiers, while user mentions are expressed as user names. To match them, we use the Twitter API to resolve the user-id and user-name reference. URL shortening: A tweet is constrained to 140 characters, so most URLs are shortened using a URL shortening service such as http: //bit.ly/.

Magnetic motion capture systems require the real actor to wear a set of sensors, which are capable of measuring their spatial relationship to a centrally located magnetic transmitter. The position and orientation of each sensor is then used to drive an animated character. One problem is the need for synchronizing receivers. The data stream from the receivers to a host computer consists of 3D positions and orientations for each receiver.

Filers also sometimes provide information in narratives that is different from the information they provided in Field 7. Second, the subject(s) for the purposes of these statistics are not necessarily the subject(s) whose information appears in Part I of either the SAR-DI or SAR-SF.
