WHAT IS A data hierarchy?
Data Hierarchy refers to the systematic organization of data, often in a hierarchical form. Data organization involves fields, records, files and so on.A data field holds a single fact. Consider a date field, e.g. "September 19, 2004". This can be treated as a single date field (e.g. birth date), or 3 fields, namely, month, day of month and year.A record is a collection of related fields. An Employee record may contain a name field(s), address fields, birth date field and so on.A file is a collection of related records. If there are 100 employees, then each employee would have a record (e.g. called Employee Personal Details record) and the collection of 100 such records would constitute a file (in this case, called Employee Personal Details file).Files are integrated into a database. This is done using a Database Management System. If there are other facets of employee data that we wish to capture, then other files such as Employee Training History file and Employee Work History file could be created as well.The above is a view of data seen by a computer user.The above structure can be seen in the hierarchical model, which is one way to organize data in a database.In terms of data storage, data fields are made of bytes and these in turn are made up of bits.
Explain the 3 level of Architecture of DBMS?
EXTERNAL LEVEL (highest level) • The user's view of the database. • Consists of a number of different external views of the DB. • Describes part of the DB for particular group of users. • Provides a powerful and flexible security mechanism by hiding parts of the DB from certain users. The user is not aware of the existence of any attributes that are missing from the view. • It permits users to access data in a way that is customized to their needs, so that the same data can be seen by different users in different ways, at the same time. CONCEPTUAL LEVEL • The logical structure of the entire database as seen by DBA. • What data is stored in the database. • The relationships among the data. • Complete view of the data requirements of the organization, independent of any storage consideration. • Represents: - ∀entities, attributes, relations - constraints on data - semantic information on data - security, integrity information Supports each external view: any data available to a user must be contained in, or derivable from the conceptual level. INTERNAL LEVEL • Physical representation of the DB on the computer. • How the data is stored in the database. • Physical implementation of the DB to achieve optimal run- time performance and storage space utilization. - Storage space allocation for data and indexes - Record description for storage - Record placement - Data compression, encryption
