The document design subtleties are steady and all-around characterized and are destined to be viable pushing ahead. All B-trees are put away in a similar circle document. Separate B-trees are utilized for each table and each record in the data set. SQLite database is kept up on plate utilizing a B-tree execution found in the btree.c source document. The vdbeaux.c record contains utilities utilized by the virtual machine and interface modules utilized by the remainder of the library to build VM programs. Different other vdbe*.c records are partners to the virtual machine. The vdbe.h header record characterizes an interface between the virtual machine and the remainder of the SQLite library and vdbeInt.h which characterizes constructions and interfaces that are private to the virtual machine itself. The virtual machine itself is totally contained in a solitary source record vdbe.c. The bytecode program made by the code generator is controlled by a virtual machine. As well as it also avoids grammatical mistakes and the grammar file is available on the parse.y that SQLite understands. The parser uses an alternate information structure that is error-free. Lemon parser performs the same task as YACC. The SQLite uses a Lemon parser to create the SQLite parser. The parser token is dependent on their specific circumstance.

If the parser has a tokenizer then it is good for the threadsafe to run at high speed. People who think about YACC may have a parser that calls the tokenizer. Most important thing is that the tokenizer calls the next component that is the parser.

The tokenizer is a computer program that can be recorded by tokenizing.

Extension APIs now and again add the enlargement name before the underscore.Įxactly when a string has a SQL expression it first analyzes and sends it to the tokenizer.

To evade name crashes, all symbols from the SQLite library start by using the prefix sqlite3, on the other hand, other symbols used for external use (all things considered, symbols which structure the API for SQLite) concatenate with an underscore, and in this route start with sqlite3_. However, in sqlite3 name crashes may happen. The other programming dialects have an interface in the source document that is in the fundamental record through this record, we can get to the information structure inside the record scope.
