Key Terminologies of Heap File Organization

1. Stack File

The heap file is responsible for being the basics of the company system. In terms of structure, we can easily picture it as an unorganized space where records are kept without any clear order. In the append scheme, the data stream is added as a new entry at the end of the existing record file, and thus a sequential list is created. This simplicity is a small thing that is an advantage in fast entries, yet it can reduce the efficiency of more sophisticated methods of restoration.

2. Page

When the heap file is organized, the pages are an approximation of the information present on the disk. On the other hand, each page is viewed as a container of information and is assumed to have a default size allocated to it by the database system. The roles of pages in managing records, which differ from each other, are that they act as boxes to hold a specific number of records placed randomly. The page table is of a fixed size and results in faster storage and retrieval operations.

3. Record

A record is defined as a collection of information elements recorded as a unit and maintained by a common owner. In database jargon, each record corresponds to one row of a table. Heap In file organization, records are volatile, associated units of data held on pages. Records contain all the information about particular items from this entity, and the totality of the records forms the contents of the heap file.

4. Slot

A slot can be thought of as a block where a record is placed inside a fixed area within a page. When a record is added to a page, it replaces the record that was previously there. The numerical system is actually closely related to the slots at the bottom of the page, which enable all the entries to be placed in systematic order. The slot concept is one of those programming mechanisms that allows each record to be stored in a certain section of the page.

Heap file organization is a fundamental method of storing data in databases. This is the simplest form, which prioritizes efficient insertion over retrieval based on specific criteria.
