SQLite Database-


SQLite is a software library that offers a system for the management of relational databases. In SQLite, the lite means light-weight in terms of configuration, database management, and resource specifications. 


With some more services including numerous high-profile initiatives, it is one of the widely available databases in the world. 


It is also embedded in the SQL database engine, and unlike any other SQL database, there is no single server process in SQLite. 

It reads and writes directly into the ordinary disk file. However, users may mistakenly delete the records from the SQLite and then it becomes necessary to recover them in order to maintain continuity of business.


What is the SQLite Database Structure?


The B-Tree structure follows the SQLite server. To maintain each index and table within the database, an individual B-Tree is used. All B-Trees are stored in an identical disk folder and file format details are stable and well-defined. In addition, the SQLite library's B-tree subsystem & rest interface is indicated by the btree.h header file. 


Pages in Database: There are one or more pages in the chief database file. If we're talking about a page's width, it's the power of 2 between 512 and 65536. The pages in a similar database are of the same size. The width of the page is calculated by a 2-byte integer, which is put at the start of the server at the offset of 16 bytes.


The header of Database: The file’s top 100 bytes comprise the database file header. The header of the file is divided into two different fields. All multibyte fields in the database file header are saved first with the most significant byte.
