Knowledge of how information is organized will allow a programmer to make more informed decisions on how to retrieve information.
A simple example of this is the binary search. If you're looking for information in a list of data, you would normally need to perform an inefficient O(n) linear search. But if you happen to know that the data will always be in sorted order, you can use a nice O(log n) binary search instead.

Which is the field of study on managing and processing information and automatic retrieval information?
Information science is the field of study that deals with managing, organizing, and processing information, as well as the automatic retrieval of information from various sources using technology and systems. It encompasses disciplines such as data management, information retrieval, and knowledge organization.
What is a collection of data organized in a manner that allows access. retrieval the data?
A database is a collection of structured data that allows for efficient storage, retrieval, and organization of data. It typically uses tables to organize information and provides mechanisms for querying and manipulating the data.
What is the difference between a knowledge base and a database?
Database is a collection of facts, figures and statistics related to an object. Data can be processed to create useful information. A knowledge base is a special kind of database for knowledge management. It provides the means for the computerized collection, organization, and retrieval of knowledge
What are the various phases of data processing?
Data processing includes the input, verification, organization, storage, retrieval, transformation, and extraction of information from data. Processing can also include the execution of a program.
What is the DIK model?
The DIK model is a framework that explains the flow of knowledge within an organization. It stands for Data, Information, Knowledge. Data is raw facts, Information is processed data, and Knowledge is derived from information through interpretation and understanding. This model helps in understanding how data is transformed into useful knowledge.
What does the retrieval of data mean?
Retrieval is the ability to search for and locate information that has been stored.
Are data base and information retrieval theoretical or applied?

What are the difference between database systems and data information retrieval systems?
A database management system (DBMS or simply database) forms the back-end of a data information retrieval system. Data retrieval is just one component of a DBMS; data input, storage and maintenance being the other major components.
Who carries out data maintenance and information retrieval in a database?
Database administrators are usually responsible for data maintenance and information retrieval in a database. They ensure databases are secure, updated, and perform regular backups. Data retrieval involves querying databases using structured query language (SQL) to extract specific information as needed.
What has the author David Ellis written?
David Ellis has written: 'Progress and problems in information retrieval' -- subject(s): Data processing, Information retrieval
What is the data centralization?
Data centralization is the process of consolidating scattered data from various sources into a centralized repository. This helps improve data management, accessibility, and security by enabling easy storage, organization, and retrieval of data from a single location. Centralizing data can also enhance data analysis and decision-making processes by providing a comprehensive view of the organization's information.
What is information retrieval?
Information retrieval is the process of accessing and retrieving relevant information from a collection of data sources. It involves searching for and retrieving documents or data that are relevant to a user's query or information need. Techniques such as indexing, querying, and ranking are commonly used in information retrieval systems to make the search process more efficient and effective.
