Simple introduction into databases elements included

Asked By 20 points N/A Posted on -

What is a database? What are records, table and field? What are the two types of database? What are the basic elements of a database? I’ve heard that there’s an old tool in VB 6.0 that can be used to create database? Can you show me how to create database using VisData? In this part, I just want to know brief explanation and simple instructions. Please do not overflow the explanation so it will be easier for me to understand everything.

Thank you very much!

Happy to support you!

A database is a collection of data related to a particular subject, which is properly organized. Databases can be created and maintained manually as well as electronically. Its basic elements can be explained as
  • DB schema
  • Schema objects
  • Indexes
  • Tables – collections of fields & record related to a particular instance 
  • Fields – the properties that describe an entity
  • Columns
  • Records – any real world object like a person, thing or place, etc.
  • Rows
  • Keys
  • Relationships
  • Data types
Yes of course, there is an old tool in VB 6.0 that can be used to create database. In order to create a database using VisData, you first have to install the soft ware, open it, assign the fields, rows, keys & other related constrains and then insert the data into the tables crated.
