What is teradata in data warehousing?
Teradata is a RDBMS system like Oracle or SQL Server but designed specifically for use in data warehousing. Data Warehouses contain extremely large amounts of data that normal RDBMS systems like oracle or sql server cannot handle comfortably. They may eventually be able handle the data but their performance may not be the best. Teradata is a system that is specifically designed for handling such extremely high volumnes of data.
What is the need for aggregation?
Aggregation is an important concept in database design where composite objects can be modelled during the design of database applications. Therefore, preserving the aggregation concept in database implementation is essential. In this paper, we propose models for implementation of aggregation in an Object-Relational Database Management System (ORDBMS) through the use of index clusters and nested tables. ORDBMS is a commercial Relational Database Management Systems (RDBMS), like Oracle, which support some object-oriented concepts. We will also show how queries can be performed on index clusters and nested tables.
How is indexing faster than sorting when accessing data from a table?
Indexing can be faster than sorting. It can also be slower. It depends on how many rows your predicate clause is selecting, and on the data dispersion represented by those index keys. If you are selecting a few rows, such as less than 4% of the table, then by all means use an index. If you are selecting a lot of rows, such as more than 25% of the table, then the use of the index will usually degrade performance, so go for the full table scan followed by a sort. (Of course, now you are adding the use of sort space, so that is a consideration.) The break-even point depends on the particular RDBMS and on the structure of the data. If your RDBMS supports EXPLAIN PLAN, then use it, and learn to know what it means. Also, make sure you understand your data, because (sometimes) only you know the best way to query it, and it might make sense to override the optimzer and force a certain execution plan based on your knowledge.

What are the advantages of rdbms over dbms?
RDBMS is a Relational Data Base Management System Relational DBMS. This adds the additional condition that the system supports a tabular structure for the data, with enforced relationships between the tables. This excludes the databases that don't support a tabular structure or don't enforce relationships between tables.
What are the different types of management systems?

Is MySQL DBMS or RDBMS?
AnswerMySQL, like most modern Database Management Systems is based on the relational model. So it is a RDBMS (Relational Database Management System).
Is oracle difficult?
Oracle is no more complex than any other RDBMS, such as MySQL or PostgreSQL. It has some unique features not found in other RDBMS', and is missing some features that may be found in other systems. Knowing "standard SQL" will give a basic level of knowledge needed to use Oracle, and then, as with all other RDBMS software, some additional learning will be required to take advantage of advanced features.
What are the subject topic for rdbms?
RDBMS is all about Relational Data Base Management System...
What is object rdbms?
An Object RDBMS is a relational database and it is part of an object-relational database. AN RDBMS might involve SQL statements with functions and user-defined data-types.
Is Fox Pro dbms or rdbms and why?
every rdbms is a dbms.as of a standard there is a criteria for any prog. lang. to become rdbms. this is defined in codds 12 rules. this all together if satisfied then any prog lang can be said to be a rdbms. but in practice we come across many examples where a prog lang is not rdbms but still provide relational database very often. ex foxpro is not rdbms because it does not satisfy one of the codds 12 rule i.e. of defining a foreign key. in foxpro you cannot define a foreign key. but since it has tables in it and can provide relations we can term foxpro as pseudo rdbms(partial rdbms)..........
