What does database table mean?
In relational databases and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect. A table has a specified number of columns, but can have any number of rows.

A flat-table database is one that uses a single table to store all relevant data. By contrast, a relational database uses several tables to store relevant data, and then estab…lishes 'relations' between them using unique identifiers ... such as primary keys and foreign keys. Flat-table databases are ok if the data is not too complex or repetitive. Relational databases are good when the data is complex and repetative. For example: Keeping track of a personal music CD collection - if one is lazy - can simply be done in a flat-table database table (or a spread sheet). It can also be done in a relational database by creating a few tables and relating them. One table can be artist (with a primary key), another table can be album (relates to a single artist primary key), and a third can be a record label table (which can relate to many artist primary keys). This is a very high-level view of the differences. I .
A table is an object inside a database. A database has tables of data, views, indexes and programs. A database can have 10 or thousands of tables. More specifically, a table i…s a collection (rows) of data on a single related topic. For example, the Employees table would have employee data, each row being a different employee, but it would not have Inventory data. That would be in the Inventory table. A database is a collection of objects, primarily tables, but also indexes to help search the tables, views that filter, select and combine the data in the tables, and stored procedures (pre-defined programs that perform specific actions on the database).
The following are some of the benefits of normalization: removes redundancies achieves consistency. improves data accessing speed improves the performance of the server decrea…ses time accessing from the database. generally efficient working of the application Normalization was introduced just to have CONSISTENT Data by avoiding REDUNDANCIES. While doing so, it introduces some overhead by having few new tables which definitely has an impact over PERFORMANCE and SPEED, because of involving many tables in the JOIN operation which itself proves the complexity. In short, you can prefer normalization for having Consistent and Clean Data with the cost of Performance and Speed.
It is a collection of rows and columns and made up of small entities called cells. These cells are used to store data and user information in a well structured and organized… manner.
A table in a database contains a collection of records (or rows). Each record contains one or more fields (or columns).
Table design in Microsoft Access can be performed by right clicking the table name in navigation view (column that runs down the left hand side of Access that is headed 'All A…ccess Objects' by default) or by clicking the "geometry set" icon on the far left hand side of the ribbon called "View" with the table actually open. In Design view you can create and rename fields and assign a "Data Type" to represent the type of data being entered into each field such as Text, Date, Number etc. Hope this helps.
The database table has a physical existence in the database. A view is a virtual table, that is one that does not actually exist. View is made up of a query on one or ma…ny tables in a database.
Tables organize the data into a form that can be referenced from two or more inputs.

aga A table means that it holds infomation and can be easily accessed!
A database view is a dynamic table compared to the 'fixed' ones. A view contains a select statement, which dynamically updates the table everytime the view is looked at and …the data has changed. Since these queries are compiled they will be faster than normal queries. Example: Table A: ID, Integer FullName, String Table B: AID, Integer Address, String You would like to find the address for each person. Instead of making a long select each time you want a specific address for a specific person. You could make a select, that joins the data, make it into a view, and then use the View afterwards. Like: SELECT a.id, a.fullname, b.address FROM a, b WHERE a.id = b.aid; This will be your view, tView. Now the data: SELECT * FROM tView WHERE fullname = 'John Randomness'.
On disks in organizers called Tablespaces(TS). Tablespaces contain 1 or more data files. When you create a table, you tell it in the DDL what TS will house it. Gib
Tables are used to provide reference to comparative data when individual comparisons are not possible or preferable. In a database, a table provides the value associated with …two (or more) separate inputs.
They are used to store records of people to organize
It depends on the database implementation. Some use individual files to represent each table, others allocate blocks of storage and use proprietary storage methods that includ…e concepts such as linked lists and the like.
A table is contained within the database and consists of columns and rows. A table is meant to store data and, in relational databases, are related to other tables within …the same database.
The primary key identifies rows (records) in a database table. A primary key can be composed of multiple columns (fields).
