Indexed databases are databases that use an index data structure to efficiently retrieve and access data. The index stores keys and pointers to the actual data, allowing for faster search and retrieval of information. Indexes help in optimizing performance by reducing the number of disk accesses needed to locate specific data.
Information resources that point the user towards data and are organized according to a predefined scheme are called indexes or databases. They provide a systematic way to locate and access specific information by categorizing and arranging it in a structured manner. Examples include online databases, library catalogs, and search engines.
The indexes in the library catalogue help users find the books they need quickly and easily.
In databases, properties are attributes or characteristics of database elements such as tables, columns, or indexes. They define specific settings or configurations that determine how the database or its elements behave. Properties can be used to control various aspects of data storage, retrieval, indexing, and performance within a database system.
Yes, DBMSs use indexes to improve the speed of data retrieval by providing faster access to specific columns or rows in a table. Indexes help to optimize query performance by creating a structure that enables the database system to locate data quickly. Additionally, indexes can enforce uniqueness constraints, accelerate sorting and grouping operations, and support foreign key relationships between tables.

Overhead associated with maintaining indexes.
The General Reference section includes computerized databases, indexes, and abstracts on CD-ROM.

Indexes help in optimizing performance by reducing the number of disk accesses needed to locate specific data.
The index between relations databases is the common thread which ties them together. So if you have a column in each database called 'idnum' and IDNUM:001 in the first database corresponds with data in IDNUM:001 in the second database, the two databases are relational and IDNUM is their index.
Much information is available through accessing Web sites of exchanges and other organizations, such as Dow Jones and Russell Group, that have developed indexes.

The three indexes typically provided by an alphabetical index are: subject index, which lists topics and themes in alphabetical order; name index, which includes individuals or organizations mentioned in the document; and geographical index, which organizes locations referenced throughout the text. These indexes facilitate easy navigation and quick reference to specific information within the document.
Perhaps the person conducting the research does not have the expertise in the area needed, or knowledge of how to use the various catalogs, indexes, databases, and other resource materials.
Indexes provide useful information including: Even with their limitations, indexes show trends and changes in investing patterns. They can give snapshots of market activity, even if they don't tell the whole story. Indexes provide a yardstick for comparison over time.
Information Technology is not a commodity. Information Technology is a service and that is why in some global stock indexes, IT stocks are classified under the service sector.
There are indexes that cut across industries; there are indexes that deal with one industry only. Indexes include varying numbers of stocks.
