[1] [2] There are three main API options when considering connecting to a MySQL database server: PHP's MySQL Extension; PHP's MySQLi ...

[13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
JasperReports reports are defined in an XML file format, called JRXML, [2] which can be hand-coded, generated, or designed using a tool. The file format is defined by a document type definition or XML schema for newer versions, providing limited interoperability. [19] [2] JRXML files have the filename extension .jrxml.
Consider a database of sales, perhaps from a store chain, classified by date, store and product. The image of the schema to the right is a star schema version of the sample schema provided in the snowflake schema article. Fact_Sales is the fact table and there are three dimension tables Dim_Date, Dim_Store and Dim_Product.
