Bottom Snapshot From The Sonar Data
3,125 wordsABSTRACT Searching for mines is a time consuming and relatively hazardous operation that is heavily weighted in the favour of the miner if the defending force has not prepared the battle space beforehand. In simple terms, if the environment in which the enemy is likely to launch a mine attack is known, and the defending forces are familiar with the bottom conditions then the enemy mines are more easily localised and subsequently eliminated. The method of achieving this familiarity with the envir...
Query Language Of The Relational Systems
1,497 words... should have the same status although perhaps they are differently supported by the system itself. Persistence is one of the most basic features of a DBMS (at least the most evident one) and hence of an OODBMS. It is the ability of the programmer to have his / her own data survive the execution of a process so that he / she can eventually reuse it in another process. For an object-oriented system, there is an additional requirement which stems from the extensibility requirement, that any obje...
Interview And Objective Measurement Methods
325 wordsINTERVIEW VERSUS OBJECTIVE MEASUREMENT METHODS OF DATA COLLECTION By: Julhusin B. JalisanABSTRACTOne of the main causes of failure in any research undertaking is the wrong choice of data collection method. While the confidence level can be established, and variability can be computed for estimating probable sampling errors, it is virtually impossible to the same to errors introduced through bias either positively or negatively. The interview method, although relatively economical, relies heavily...
Use Of The 64 Bit Video Card
3,018 wordsVideo Cards Introduction People are living in a three-dimensional space. They know what is up, down, left, right, close and far. They know when something is getting closer or moving away. However, the traditional personal computers can only make use of two dimensional space due to relatively low technology level of the video cardin the past. As the new technology has been introduced to the video card industry in recent years, the video card can now render 3 D graphics. Most of the PC computer ga...
Object Oriented Database Model
914 wordsComparing and Contrasting the Relational Database Model and OO Model The relational database model is based upon tables or relations. In this model, the physical implementation of the database is abstracted away from the user. Users query the database using a high-level query language, such as SQL. The relations are made up of columns, which have headings indicating the attribute represented by that column. Tables have key fields, which can be used to identify unique records. Keys relate tables ...
Target And Incident Y Distances
842 wordsMomentum Lab The game of pool sounds simple, all one must do is hit the cue ball, towards another ball, and making that ball fall into a pocket. It sounds simple, but how come only a small percentage of people are actually good at it The people that excel at the game of pool are probably not physically stronger, but you can be sure that they know all about momentum. Momentum is literally mass in motion; it is a vector quantity. Momentum is equal to its velocity multiplied by its mass. The purpos...
Variables For Oracle 9 I Object Types
1,456 wordsKey Features of the Object-Relational Model Oracle implements the object-type system as an extension of the relational model. The object-type interface continues to support standard relational database functionality such as queries (SELECT... FROM... WHERE), fast commits, backup and recovery, scalable connectivity, row-level locking, read consistency, partitioned tables, parallel queries, cluster database, export / import, loader, and so forth. But SQL and various programmatic interfaces to Orac...
Introduction Object Oriented Databases Management Systems
1,141 wordsPosition Paper: How can Object Oriented Design help the Migration from Relational to Object Oriented database architecture? Introduction Object Oriented Databases Management Systems (OODBMSs) add database functionality to object programming languages. They bring much more than consistently storing programming language objects. OODBMSs extend the principals of object programming languages to provide full database programming capability, while keeping the original language compatibility. The best ...
Encapsulated Data Of The Object
3,348 wordsObject-Oriented Programming the desire for an easy transition from existing languages ABSTRACT Now it is clear that Object-Oriented Software Development is here to stay and is the preferred way to develop software. To be successful in the world of object-oriented programming (OOP) one has to unlearn quite a few of the habits acquired from the years of procedure-oriented programming and learn some new ways of looking at the problems. Object-oriented technology is the wave of today. Thus it is my ...
