Data logging can be achieved with transaction groups or SQLTags History. Store-and-Forward is an engine that buffers SQL database writes to memory and caches them to a local disk when an external database connection is unavailable. Upon reconnection the data is forwarded to the server in aggregated time-efficient batches. [8]
Fact_Sales is the fact table and there are three dimension tables Dim_Date, Dim_Store and Dim_Product.

Overview of a data-modeling context: Data model is based on Data, Data relationship, Data semantic and Data constraint. A data model provides the details of information to be stored, and is of primary use when the final product is the generation of computer software code for an application or the preparation of a functional specification to aid a computer software make-or-buy decision.
sqlmap is an open-source penetration testing tool for automating the detection and exploitation of SQL injection flaws.
One of the arguments against using an OODBMS is that it may not be able to execute ad-hoc, application-independent queries. [citation needed] For this reason, many programmers find themselves more at home with an object-SQL mapping system, even though most object-oriented databases are able to process SQL queries to a limited extent. Other ...
The first draft of the Microsoft Data Access API was published in April 1989, about the same time as Lotus' announcement of Blueprint. [4] In spite of Blueprint's great lead – it was running when MSDA was still a paper project – Lotus eventually joined the MSDA efforts as it became clear that SQL would become the de facto database standard.

An SQL select statement and its result. In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data.
For example, if a user wanted to pull a value from Microsoft Excel which was contained in a spreadsheet called "Book1.xls" in the cell in the first row and first column, the application would be "Excel", the topic "Book1.xls" and the item "r1c1".
