Across each row, the columns (called fields) contain the individual pieces of data that make up a record — for example, a customerʼs name and contact information, or the number of bottles purchased in a transaction, the amount paid, and where they were shipped.

A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS). Most databases use structured query language (SQL) for writing and querying data.

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.

A database field is a set of data values, of the same data type, in a table. It is also referred to as a column or an attribute. Most databases also allow fields to hold complex data like pictures, entire files, and even movie clips. A field that allows the same data type does not mean it only has simple text values.

In computer science, data that has several parts, known as a record, can be divided into fields. Relational databases arrange data as sets of database records, so called rows. Each record consists of several fields; the fields of all records form the columns. Examples of fields: name, gender, hair colour.

The set of real numbers and the set of complex numbers each with their corresponding addition and multiplication operations are examples of fields. However, some non-examples of a fields include the set of integers, polynomial rings, and matrix rings.

A database field is a single piece of information from a record. A database record is a set of fields. The Fields window displays the record-level fields that are contained in a Progeny database.

Types of data fields

• List (text values)
• List (numeric values)
• Text.
• Memo.
• Rich Text.
• Date.
• Decimal.
• Integer.

The value of a field is a string of bytes, consisting of all bytes in the field after the first colon. In other words, it is the concatenation of all the lines in the field, except for the starting name and colon.

Follow these steps to decide how to organize your data into tables:

1. Name your database.
2. Identify the objects.
3. Define and name a table for each object.
4. Identify the attributes for each object.
5. Define and name columns for each separate attribute that you identify in Step 4.
6. Identify the primary key.

How should I organise my files?

1. Use folders – group files within folders so information on a particular topic is located in one place.
2. Adhere to existing procedures – check for established approaches in your team or department which you can adopt.

File – a group of related records. Files are frequently classified by the application for which they are primarily used (employee file). A primary key in a file is the field (or fields) whose value identifies a record among others in a data file.

A database is generally used for storing related, structured data, with well defined data formats, in an efficient manner for insert, update and/or retrieval (depending on application). On the other hand, a file system is a more unstructured data store for storing arbitrary, probably unrelated data

The Database Designer is a visual tool that allows you to design and visualize a database to which you are connected. To visualize a database, you can create one or more diagrams illustrating some or all of the tables, columns, keys, and relationships in it

An NDF file is a user defined secondary database file of Microsoft SQL Server with an extension . ndf, which store user data. Moreover, when the size of the database file growing automatically from its specified size, you can use . ndf file for extra storage and the . ndf file could be stored on a separate disk drive

As per Microsoft, Primary datafile can not be removed so you can not remove it

A Microsoft SQL database consists a primary data file (mdf) a secondary data file (ndf) and a transaction log file (ldf). MDF stands for Main Database File and contains all the information in a database. LDF records all the transactions and changes to the database. The ldf is critical for disaster recovery

A file is a collection of data stored in one unit, identified by a filename. It can be a document, picture, audio or video stream, data library, application, or other collection of data. Documents include text files, such as a Word documents, RTF (Rich Text Format) documents, PDFs, Web pages, and others.

A collection of data or information that has a name, called the filename. Almost all information stored in a computer must be in a file. There are many different types of files: data files, text files , program files, directory files, and so on. For example, program files store programs, whereas text files store text.

A file is an object on a computer that stores data, information, settings, or commands used with a computer program. In a GUI (graphical user interface), such as Microsoft Windows, files display as icons that relate to the program that opens the file

In law, filing is the delivery of a document to the clerk of a court and the acceptance of the document by the clerk for placement into the official record. Usually a filing fee is paid which is part of court costs.

Filing means keeping documents in a safe place and being able to find them easily and quickly. Documents that are cared for will not easily tear, get lost or dirty. A filing system is the central record-keeping system for an organisation. It helps you to be organised, systematic, efficient and transparent

Advantages of good filing system

• Efficiency. The office staff can easily locate and use the records properly without any delay under good filing system.
• Ready Reference. Filing arrangement helps the office staff to refer the relevant papers and documents very quickly.
• Protection.
• Planning.
• Better Control.
• Quality Decision.
• Evidence.
• Legal Compliance.

The most important purpose of a file system is to manage user data. This includes storing, retrieving and updating data. Some file systems accept data for storage as a stream of bytes which are collected and stored in a manner efficient for the media.

The following are the main objectives of filing:

• To preserve documents. The main objective of filing is to preserve the past and present documents from possible loss and damage.
• To provide information.
• To act as proof.
• To increase efficiency.
