A flat file system usually stores the same type of information over and over again, whereas a relational database does not. A flat file system might store zip-codes and their explanation (location of the zip code) over and over again, each time per record. A relational database stored the explanation for any given zip-code only once, and looks that information up when it needs it. --

RossFlat file databases store data in a single table or file without any relationships between the data. Relational databases organize and store data in multiple tables that are related to each other using keys, allowing for more complex querying and data manipulation. Relational databases provide greater data integrity, scalability, and flexibility compared to flat file databases.

Why is it better to use a relational database instead of a flat file database?
Relational database has many advantages over the flat file database: 1. Avoids data duplication. 2. Avoids inconsistent records. 3. Easier to change data. 4. Easier to change data format. 5. Data can be added and removed easily. 6. Easier to maintain security.
The developer of a relational database refers to a file as?
In the context of a relational database, a file is typically referred to as a table. Tables are used to store structured data in rows and columns, allowing for efficient organization and retrieval of information. Each table represents a distinct entity or concept within the database schema.
What is the difference between object oriented model and relational database model?
see the link below http://www.freetutes.com/systemanalysis/sa8-comparison-relational-model-oo-model.html Different database models differ in their representation of relationships. In relational model, connections between two relations are represented by foreign key attribute in one relation that reference the primary key of another relation. Individual tuples having same values in foreign and primary key attribute are logically related. They are physically not connected. Relational model uses logical references. In object oriented model, relationships are represented by references via the object identifier (OID). This is in a way similar to foreign keys but internal system identifiers are used rather than user-defined attributes. The Object Oriented model supports complex object structures by using tuple, set, list, and other constructors. It supports the specification of methods and the inheritance mechanism that permits creation of new class definitions from existing ones. In relational model, each base relation is implemented as a separate file. If the does not specify any storage structure, most RDBMS will store the tuples as unordered records in the file. It allows the user to specify dynamically on each file a single primary or clustering index and any number of secondary indexes. It is the responsibility of user to chObject Orientedse the attributes on which the indexes are set up. Some RDBMSs give the user the option of mixing records from several base relations together. It is useful when related records from more than one relation are often accessed together. This clustering of records physically places a record from one relation followed by the related records from another relation. In this way the related records may be retrieved in most efficient way possible. Object Oriented systems provide persistent storage for complex-structured objects. They employ indexing techniques to locate disk pages that store the object. The objects are often stored as byte strings, and the object structure is reconstructed after copying the disk pages that contain the object into system buffers. Relational model has keys, entity integrity, and referential integrity. The constraints supported by Object Oriented systems vary from system to system. The inverse relationship mechanism supported by some Object Oriented systems provides some declarative constraints. There are languages such as SQL, QUEL, and QBE are available for relational systems. These are based on the relational calculus. In Object Oriented systems, the DML is typically incorporated into some programming language, such as C++. Hence, the structures of both stored persistent objects and programminglanguage transient objects are often compatible. Query languages have been developed for Object Oriented databases. Work on a standard Object Oriented model and language is progressing, but no complete detailed standard has emerged as yet.
A developer of a relational database refers to a field as a?
In a relational databaseA field is called a column.A record is called a row (of multiple columns).A file is called a table (of multiple rows).
A saved workbook is referred to as a?
A saved workbook is referred to as a file in Microsoft Excel. This file typically has a .xlsx extension and contains all the data, formatting, and calculations that have been input into the workbook.
