is an organized collection of integrated and related tables. Database Management System (DBMS) is software that allows you to create a database, manage the data in the database by adding, deleting, and updating records, sort and retrieve data, and create queries and reports relating to that data. relational database.
Database. is an integrated collection of logically related tables. Primary key. is the field in a record that uniquely identifies each record. Database management system DBMS.
Relational DatabaseGlossaryRelational DatabaseA database that contains a collection of related tables.Relational Database management system (Relational DBMS)A database management system in which data is organized as a collection of related tables.
A record is a collection of related fields. An Employee record may contain a name field(s), address fields, birthdate field and so on. A file is a collection of related records. Tables are also called datasheets.
In a relational database, a collection of related records or rows. A single category of data to be stored in a database, such as customer names or employee telephone numbers. Also called a column. A field in a database.
A table typically has a column or combination of columns that contain values that uniquely identify each row in the table. This column, or columns, is called the primary key (PK) of the table and enforces the entity integrity of the table.
database. integrated collection of logically related tables.
A database is an organized collection of logically related data, usually designed to meet the information needs of multiple users in an organization.
A collection of related data is called Database. A database is a data structure that stores organized information.
Collection of data is called data collection.
Database is a collection of related information.
What is a collection of related files called tables that consist of records of data separated by fields?
Database Management System Software (DBMS) a collection of related files called tables that consist of records (rows) of data separated by fields (columns) that can be queried to produce populations of information.
Character – A character is the most basic logical data element. It consists of a single alphabetic, numeric, or other symbol.
Cylinders differentiate files stored on the same track and sector of different platters.
Data may be grouped into four main types based on methods for collection: observational, experimental, simulation, and derived.
Database is a collection of data related to each other. Data type are set to control the properties of the data type of field.
Every table can have (but does not have to have) a primary key. The column or columns defined as the primary key ensure uniqueness in the table, no two rows can have the same key.
Record: Record is a collection of values or fields of a specific entity. Eg. An employee, Salary account, etc. Field: A field refers to an area within a record which is reserved for a specific piece of data. Table: Table is the collection of records of specific types.
Alternate Keys (AK) – key associated with one or more columns whose values uniquely identify every row in the table, but which is not the primary key. Primary Foreign Key (PFK) – key which acts as primary key in more than one table which occurs in tables with an identifying relationship.
Introduction to Alternate Key in SQL. The alternate key is a combination of one or more columns whose values are unique. A table consists of one or more Candidate keys, in which one will be Primary Key and rest of the keys, are called as Alternate keys. Alternate Key is not part of the primary key.
Relations or tables A relation is defined as a set of tuples that have the same attributes. A tuple usually represents an object and information about that object. Objects are typically physical objects or concepts. A relation is usually described as a table, which is organized into rows and columns.
Metadata means “data about data”. Metadata is defined as the data providing information about one or more aspects of the data, it is used to summarize basic information about data which can make tracking and working with specific data easier. Some examples include: Means of creation of the data.
Is a collection of related data and data is a collection of facts and figures that can be processed to produce information?
Database is a collection of related data and data is a collection of facts and figures that can be processed to produce information. A database management system stores data in such a way that it becomes easier to retrieve, manipulate, and produce information.
A collection of related records in Database is known as file.
Cylinders differentiate files stored on the same track and sector of different platters.
o Important characteristics of secondary storage ▪ Media are the physical material that holds the data and programs. Capacity measures how much a particular storage medium can hold. Storage devices are hardware that reads data and programs from storage media.
Answer: A collection of related data is called Database.
So desc or describe command shows the structure of table which include name of the column, data-type of column and the nullability which means, that column can contain null values or not.
A table has records (rows) and fields (columns). A record: Contains specific data, like information about a particular employee or a product. A field: Contains data about one aspect of the table subject, such as first name or e-mail address. A field value: Each record has a field value.
A record is simply a set of data stored in a table, for example, a customer record. Since a new row creates a new entry in the table/spreadsheet, it is called a record. The same is true in a database: records are stored in rows that make up the table. The fields in the database are the columns.

Keys: Primary key (PK) – value which uniquely identifies every row in the table. Foreign keys (FK) – values match a primary or alternate key inherited from some other table. Primary Foreign Key (PFK) – key which acts as primary key in more than one table which occurs in tables with an identifying relationship.
A primary key is the column or columns that contain values that uniquely identify each row in a table.
A Surrogate Key in SQL Server is a unique identifier for each row in the table. It is just a key. There is only requirement for a surrogate Primary Key, which is that each row must have a unique value for that column. A Surrogate Key is also known as an artificial key or identity key. It can be used in data warehouses.
For most design purposes the terms table and relation refer to the same thing – a collection of rows and columns (or tuples and attributes), but if we want to get into the details, a relation contains sets (no duplicates allowed) while a table contains bags (duplicates allowed).
In a relational database, the table is a relation because it stores the relation between data in its column-row format. The columns are the table’s attributes, and the rows represent the data records. A single row is known as a tuple. As with the table names, no attributes can have the same name.
