External references in assembly language are managed by the assembler through a process called linking. When an assembler encounters an external symbol, it generates a placeholder in the object file and records the symbol's name and its expected address. During the linking phase, the linker resolves these placeholders by matching them with the actual addresses of the external symbols defined in other object files or libraries. This allows multiple modules to reference shared code or data seamlessly.
A data record is a collection of various fields of data (like name, organisation, sex, age etc), whereas a database is a collection of records tables. (And views, indexes, stored procedures, and other stuff;)
ORG is an assembler directive that sets the address of the next generated instruction or data byte.
An assembler is a type of software that translates assembly language, a low-level programming language closely related to machine code, into executable machine code for a computer's processor. A schema, on the other hand, is a blueprint or structure that defines how data is organized, often used in databases to outline the relationships and constraints between different data entities. In essence, an assembler converts human-readable code into machine-readable instructions, while a schema organizes and defines data for efficient storage and retrieval.
Assembler operation in bus encoding refers to the process of translating assembly language instructions into machine code that the hardware can execute. This involves encoding the data and operation codes (opcodes) into binary format suitable for transmission over a bus system. The bus encoding ensures that the signals representing the instructions and data are efficiently transmitted between various components of a computer system, minimizing errors and maximizing speed. Overall, it plays a critical role in the interface between software and hardware.
APCB and APCBXL are two of the many data structures used in Assembler. They are mostly used for EXIT routines. Routines are nothing but simple logics

Extraction, Transformation, and Loading (ETL) is a data integration process used to consolidate data from multiple sources into a single data warehouse or database. In the extraction phase, data is collected from various sources, such as databases, flat files, or APIs. The transformation phase involves cleaning, enriching, and structuring the data to meet business requirements. Finally, in the loading phase, the transformed data is loaded into the target system for analysis and reporting.
cserial.com is the biggest online data base. A neat website maintaining the data base pertaining to various software applications. One of the best over the subject.
Assembler However, because the computer does not understand mnemonics, we utilise Assembler to convert them into machine language. Assembler is a machine code translator that accepts assembly code as input and outputs machine code. To learn more about data science please visit- Learnbay.co
The information processing cycle refers to the sequence of stages involved in processing data into meaningful information. It typically consists of four main phases: input, processing, output, and storage. During the input phase, data is collected; in the processing phase, the data is manipulated and analyzed; the output phase involves presenting the processed information, and in the storage phase, data is saved for future use. This cycle is fundamental in computer systems and various information management processes.

data base means a collection of data,which may be inter related. data base management system is a collection of programs for managing the data base.
ORG is an assembler directive that sets the address of the next generated instruction or data byte.
