SQLite1 is a lightweight (but surprisingly powerful) implementation of a SQL database. SQLite is the standard database software for iOS, Android, and Windows RT. It is installed on over a billion mobile app needs to access the database, it makes a REST call to the cloud. Most user operations require network activity. Zumero enables a "replicate and sync" model for mobile database apps. The device has its its own copy of the database. The app can interact with the database without involving the network, so queries and updates are faster and more reliable. Synchronization with the server can be handled entirely0 码力 | 57 页 | 199.89 KB | 1 年前3SQLite in Android
SQLite in Android 1 What is a database? • relational database: A method of structuring data as tables associated to each other by shared attributes. • a table row corresponds to a unit of data called define, manage, and search data 2 Why use a database? • powerful: can search, filter, combine data from many sources • fast: can search/filter a database very quickly compared to a file • big: scale abstraction between stored data and app(s) common syntax: database programs use same SQL commands 3 Relational database • A database is a set of tables • Each table has a primary key — a column0 码力 | 40 页 | 707.67 KB | 1 年前3SQLite Statements
the table or database - Create, Read, Update, or Delete. CREATE CREATE a database sqlite3 <database_name>.db This statement starts the sqlite3 program with the database file specified open.
