Logical data elements are the fundamental units of data that represent specific pieces of information in a structured format. They are defined by their meaning and context within a system, allowing for clear communication and processing of data. Examples include attributes like customer names, transaction dates, or product IDs, which are crucial for data analysis and management. Logical data elements help ensure consistency and accuracy in data handling across various applications and databases.

What difference between logical and physical design?
Logical design refers to the abstract representation of the data and the relationships among data elements, focusing on how data is organized and accessed without considering the physical storage details. In contrast, physical design involves the actual implementation of the logical design, specifying how data will be stored on hardware, including file structures, indexing methods, and data storage formats. Essentially, logical design is about "what" data is needed and "how" it relates, while physical design deals with "where" and "how" that data is physically stored and retrieved.

What can be typed and entered into a cell?
Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.Any kind of data, including text, numbers, dates, times and logical data can be entered into a cell.
What was a logical way to group elements as more and more elements were discovered?
The logical way is to be remembered that chemical properties of elements have a periodic character.
Is a logical unit of data and is a physical unit of data?
A logical unit of data is a virtual representation of data while a physical unit of data is the actual storage of data on a physical device. The logical unit of data is how data is organized and manipulated from a software perspective, while the physical unit of data is how data is stored on hardware such as disks or memory.
What separates the physical aspect of data storage from the logical aspects of data representation?
A schema separates the physical aspect of data storagefrom the logical aspects of data representation.
What is logical file?
Logical file is a type of file that provides a view of the data stored into the Physical file. It does not contain data. A logical file contains only an index to the data stored into the physical file.
Which one between logical and physical data independent is harder to achieve and why?
the logical data independence is hard to achieve because all the manipulation is belonging in logical data independence but in physical data independence only show the physical view .
What elements might the data link layer add to its pdu a physical addresses b logical addresses c data d crc?
The data link layer typically adds physical addresses (also known as MAC addresses) to its Protocol Data Unit (PDU) to ensure that data is delivered to the correct device on a local network. Additionally, it often includes a CRC (Cyclic Redundancy Check) for error detection, ensuring the integrity of the transmitted data. Logical addresses and the original data payload are not added at this layer; logical addressing is handled at the network layer above it.
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. With a complete logical database design in place an analyst begins to specify the logic of the particular computer programs and queries needed to maintain and report the database content. The person who maintain or responsible to perform the above task is known as Logical Database designer.
What is logical data independence and its importance?
logical data independence 1)the ablity to modify the conceptual scheme without causing application program to be rewritten. 2)usually done when logical structure of database is altered. The logical data independence is the key side of database management system for maintaining data integrity and for maintain overall effectiveness of data usage. Logical data nouns is an important part of three schema architecture which allows the change or modification of conceptual schema short disturbing the external schema. The modifications in conceptual schema may include alteration of entities, attributes, relationships etc. Changing any of these elements will not disturb the external application programs which is a key advantage of logical information independence feature of database management systems.
