Logical database design is the process of designing the database at a conceptual level as opposed to a physical level. There are many advantages of conceptual database design, such as the ability to design the database without having to commit to a particular database management system, to produce a document that is readable and understandable to everyone in the company (not just the database person) and to produce an overall design document that can be saved as a part of the documentation of the database for future enhancement, maintenance and support work. Logical database design produces documents for use in the same way that architects produce blueprints for building purposes.

What is a logical database designer?
* Logical database design: * ensuring, via normalisation procedures and the definition of integrity rules, that the stored database will be non-redundant and properly connected; * Physical database design: * specifying how database records are stored, accessed and related to ensure adequate performance. What is logical database designerThe major role of logical database design is to transform the combined, reconciled data specifications into basic or atomic elements following the well established rules for well structures data specifications.

Difference between logical database and physical database?
A logical database refers to the conceptual schema or model of data relationships and structures, independent of how data is stored or accessed. On the other hand, a physical database involves the actual implementation of the database on a specific hardware system, detailing how data is stored and accessed. The logical database design focuses on the organization of data, while the physical database design focuses on optimizing performance and storage efficiency.

What is schema instance?
In DBMS,Schema is the overall Design of the Database.Instance is the information stored in the Database at a particular moment.In programming,you declare a variable which corresponds to "Schema".But its values changes as and when required which corresponds to "Instance". Google about levels of Database Abstraction. Physical Schema describes database design at physical level while a logical schema describes the database design at the logical level.A database may also have several schemas at the view level, sometimes called subschemas, that describe different views of the database.

What is the meaning of database design?
There is only one meaning of the words database design. Data base design means the process of creating a very detailed data model of a database. It is used for a database, of course. Hello, Database design is part of system development, it is the process of producing a detailed data model of a database. A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. Databases are used everywhere in the world of web development. - conceptual database design - logical database design - physical database design Database designing , website designing & development requires proper knowledge about that. If anyone wants more information about that can communicate with the Hvantage Technology. I also visited this site it has all related information.
