Manage non-relational data stores in Azure Explore non-relational data offerings in Azure---------- Introduction Completed 100 XP 1 minute Data comes in all shapes and sizes, and can be used for a large number of purposes. Many organizations use relational databases to store this data. However, the relational model might not be the most appropriate schema. The structure of the data might be too varied to easily model as a set of relational tables. For example, the data might contain items such as video, audio, images, temporal information, large volumes of free text, encrypted information, or other types of data that aren't inherently relational. Additionally, the data processing requirements might not be best suited by attempting to convert this data into the relational format. In ...
Introduction Completed 100 XP 2 minutes In the early years of databases, every application stored data in its own unique structure. When developers wanted to build applications to use that data, they had to know a lot about the particular data structure to find the data they needed. These data structures were inefficient, hard to maintain, and hard to optimize for delivering good application performance. The relational database model was designed to solve the problem of multiple arbitrary data structures. The relational model provided a standard way of representing and querying data that could be used by any application. From the beginning, developers recognized that the chief strength of the relational database model was in its use of tables, which were an intuitive, efficient, and flexible way to store and access structured information. The simple yet powerful relational model is used by organizations of all types and sizes for a broad variety of information management needs. R...
