Features of traditional database?
the traditional database do not follow these rulesDr. E. F. Codd's 12 rulesfor defining a fully relational databaseNote that based on these rules there is no fully relational database management system available today. In particular, rules 6, 9, 10, 11 and 12 are difficult to satisfy.Foundation RuleA relational database management system must manage its stored data using only its relational capabilities.Information RuleAll information in the database should be represented in one and only one way - as values in a table.Guaranteed Access RuleEach and every datum (atomic value) is guaranteed to be logically accessible by resorting to a combination of table name, primary key value and column name.Systematic Treatment of Null ValuesNull values (distinct from empty character string or a string of blank characters and distinct from zero or any other number) are supported in the fully relational DBMS for representing missing information in a systematic way, independent of data type.Dynamic On-line Catalog Based on the Relational ModelThe database description is represented at the logical level in the same way as ordinary data, so authorized users can apply the same relational language to its interrogation as they apply to regular data.Comprehensive Data Sublanguage RuleA relational system may support several languages and various modes of terminal use. However, there must be at least one language whose statements are expressible, per some well-defined syntax, as character strings and whose ability to support all of the following is comprehensible:data definitionview definitiondata manipulation (interactive and by program)integrity constraintsauthorizationtransaction boundaries (begin, commit, and rollback).View Updating RuleAll views that are theoretically updateable are also updateable by the system.High-level Insert, Update, and DeleteThe capability of handling a base relation or a derived relation as a single operand applies nor only to the retrieval of data but also to the insertion, update, and deletion of data.Physical Data IndependenceApplication programs and terminal activities remain logically unimpaired whenever any changes are made in either storage representation or access methods.Logical Data IndependenceApplication programs and terminal activities remain logically unimpaired when information preserving changes of any kind that theoretically permit unimpairment are made to the base tables.Integrity IndependenceIntegrity constraints specific to a particular relational database must be definable in the relational data sublanguage and storable in the catalog, not in the application programs.Distribution IndependenceThe data manipulation sublanguage of a relational DBMS must enable application programs and terminal activities to remain logically unimpaired whether and whenever data are physically centralized or distributed.Nonsubversion RuleIf a relational system has or supports a low-level (single-record-at-a-time) language, that low-level language cannot be used to subvert or bypass the integrity rules or constraints expressed in the higher-level (multiple-records-at-a-time) relational language.

What is a repository for definitions of data processes data flows data stores and data elements.?
A data dictionary is a repository that contains definitions of data processes, data flows, data stores, and data elements used in an organization. It helps to provide a common understanding of data terminologies and structures within a dataset or system. Data dictionaries are often used to maintain consistency and clarity in data management and analysis processes.
Data formats and data collection?
Data formats: It is formating all data file from pcs.whatever it is not use.suppose when data is full,and some data we want to delete it.. Data collection: It is the collection of new data file.when new data is collecting..
