LevelDB is used as the backend database for Google Chrome's IndexedDB and is one of the supported backends for Riak. [8] Additionally, Bitcoin Core and go-ethereum store the blockchain metadata using a LevelDB database. [9] Minecraft Bedrock Edition uses a modified version for chunk and entity data storage. [10] Autodesk AutoCAD 2016 also uses ...

Go was designed at Google in 2007 to improve programming productivity in an era of multicore, networked machines and large codebases. [22] The designers wanted to address criticisms of other languages in use at Google, but keep their useful characteristics: [23]
Scaffolding is a technique supported by some model–view–controller frameworks, in which the programmer can specify how the application database may be used.The compiler or framework uses this specification, together with pre-defined code templates, to generate the final code that the application can use to create, read, update and delete database entries, effectively treating the templates ...
In software, a data access object (DAO) is a pattern that provides an abstract interface to some type of database or other persistence mechanism. By mapping application calls to the persistence layer, the DAO provides data operations without exposing database details.
For example, instead of using commands such as insert, delete, and update to access a specific table in a database, a class and a few stored procedures could be created in the database. The procedures would be called from a method inside the class, which would return an object containing the requested values.
The "help" index of commands in VFP 9 has several hundred commands and functions described. The examples below show how to code the creation and indexing of tables, however VFP has table and database builder screens which create the tables and indexes without making you write code. Output of the Data handling program.
BDD suggests that software tests should be named in terms of desired behavior. [5] [7] Borrowing from agile software development the "desired behavior" in this case consists of the requirements set by the business — that is, the desired behavior that has business value for whatever entity commissioned the software unit under construction.
