Publisher: site This text by noted digital forensics expert, Paul Sanderson, provides investigators with low-level technical details useful in analysing SQLite database files. Every computer and phone uses hundreds of SQLite databases and there are over one trillion SQLite databases in active use. Hence, the importance of examining the data held in these databases in an investigation, including deleted data when possible, is paramount. This book fully explains the format of the SQLite database file. It shows how records are encoded, how to decode them manually and how to decode records that are partially overwritten. It also describe how the workings of SQLite, and in particular the journal and WAL, can be used to ascertain what has happened in a manner that cannot be determined from the data alone.
It describes design principles, engineering trade-offs, implementation issues, and operations of SQLite. This book covers the basic and advanced topics with equivalent simplicity and detail, in order to enable readers to quickly grasp and implement the concepts to build an application database. This book takes a hands-on, example-based approach to help readers understand the core topics of SQLite and Android database-driven applications. This book focuses on providing you with latent as well as widespread knowledge about practices and approaches towards development in an easily understandable manner.
It presents step-by-step examples to create schema, execute transactions and access data from Android, BlackBerry and iOS applications. For BlackBerry and iOS application, the book presents ways to access the data using the command line shell. The Definitive Guide to SQLite 2nd edition, Authors: Mike Owens and Grant Allen Publisher: Apress site Outside of the world of enterprise computing, there is one database that enables a huge range of software and hardware to flex relational database capabilities, without the baggage and cost of traditional database management systems.
That database is SQLite - an embeddable database with an amazingly small footprint, yet able to handle databases of enormous size.
SQLite comes equipped with an array of powerful features available through a host of programming and development environments. The book also uses SQLite as the basis for helping newcomers make their first foray into database development.
In only a short time you can be writing programs as diverse as a server-side browser plug-in or the next great iPhone or Android application! Using SQLite Access control is handled by means of file system permissions given to the database file itself.
Databases in client-server systems use file system permissions which give access to the database files only to the daemon process.
Another implication of the serverless design is that several processes may not be able to write to the database file. In server-based databases, several writers will all connect to the same daemon, which is able to handle its locks internally.
SQLite on the other hand has to rely on file-system locks. It has less knowledge of the other processes that are accessing the database at the same time. Therefore, SQLite is not the preferred choice for write-intensive deployments.
SQLite strives to follow Postel's Rule. SQLite began as a Tcl extension. Hipp based the syntax and semantics on those of PostgreSQL 6.
In August , version 1. SQLite 2. SQLite 3. UnQLite was released as an independent database. Moreover, it is weakly typed in some of the same ways that Perl is: one can insert a string into an integer column although SQLite will try to convert the string to an integer first, if the column's preferred type is integer.
This adds flexibility to columns, especially when bound to a dynamically typed scripting language. However, the technique is not portable to other SQL products.
A common criticism is that SQLite's type system lacks the data integrity mechanism provided by statically typed columns in other products.
The SQLite web site describes a "strict affinity" mode, but this feature has not yet been added. Future versions of SQLite may include a command to introspect whether a column has behavior like that of rowid to differentiate these columns from weakly-typed, non-autoincrementing Integer Primary Keys.
Several read accesses can be satisfied in parallel.
