The concept of "Data Management" arose in the 1980s as technology moved from sequential processing (first cards, then tape) to random access processing.
Since it was now technically possible to store a single fact in a single place and access that using random access disk, those suggesting that "Data Management" was more important than "Process Management" used arguments such as "a customer's home address is stored in 75 (or some other large number) places in our computer systems." During this period, random access processing was not competitively fast, so those suggesting "Process Management" was more important than "Data Management" used batch processing time as their primary argument.
As applications moved into real-time, interactive applications, it became obvious to most practitioners that both management processes were important. If the data was not well defined, the data would be mis-used in applications. If the process wasn't well defined, it was impossible to meet user needs.

At Avari Data Management has to cover the entire spectrum of data useage within the network, Avari provide robust solutions to access, manage, control and define privieges in relation to all data.

Data access refers to a user's ability to access or retrieve data stored within a database or other repository. Users who have data access can store, retrieve, move or manipulate stored data, which can be stored on a wide range of hard drives and external devices.
​
There are two ways to access stored data: random access and sequential access. The sequential method requires information to be moved within the disk using a seek operation until the data is located. Each segment of data has to be read one after another until the requested data is found. Reading data randomly allows users to store or retrieve data anywhere on the disk, and the data is accessed in constant time.
Oftentimes when using random access, the data is split into multiple parts or pieces and located anywhere randomly on a disk. Sequential files are usually faster to load and retrieve because they require fewer seek operations
