Database management is the process of defining, manipulating, retrieving and otherwise managing data that exists in a database. When a database administrator needs to interact with a database to make changes or updates, they may do so using a database management software tool.
Databases can be described as a collection of information that is organized and categorized for easy access, search-ability, updates, and management. Databases can be used to store many different types of information, including inventory, customer data, employee data, accounting information, and other factors.
Database management systems (DBMS) provide the toolset and interface that enables a database administrator to interact efficiently with the database and its contents. A large database might have thousands, hundreds of thousands, or even millions of elements, each with its unique attributes and associated data. Without a DBMS, users and administrators would be forced to engage with the database through inefficient manual processes. Instead, a DBMS provides four main functions that facilitate interaction between users and data:
Database administrators depend on database management system tools to facilitate their interactions with different types of databases and the information contained within.
Many types of organizations across industry verticals depend on databases for information storage and to help manage core business processes. There are several different types of databases that an organization may choose to deploy based on their unique requirements and circumstances.
A hierarchical database organizes data into a tree-like structure. Windows Registry and IBM Information Management System (IMS) are two common examples of a hierarchical database. Data in this type of database is organized into fields where each field contains a single value. A field containing a value is called a record and records are organized into parent-child relationships within the tree. Each child record can only have one parent, but each parent can have multiple child records.
Hierarchical databases are useful because the relationships between records are clearly defined, but the structural limitations mean that the introduction of a new field or record might require the entire database to be restructured.
A network model database is similar to a hierarchical database in that they both organize data into a tree with parent and child records. The key difference between the network model and the hierarchical model is that a network model database allows each child record to have more than one parent record. This type of organization can be necessary for modeling more complex relationships between items in the database.
While a hierarchical model might be useful for constructing a family tree, for example, a network model database might be useful for keeping track of manufactured inventory and which parts or inputs are needed to manufacture a given product.
Relationship databases are the most widely implemented systems for organizing data. Here, data is organized as a set of independent tables that may be linked to other tables that share the same or similar data. Records in a relational database may be linked using a virtual key that is not stored in the database but may be defined by a database administrator using a database management software tool.
Some of the most common database management software tools were designed for use with relational databases, including Microsoft SQL Server, Oracle Database, MySQL and IBM DB2.
Object-oriented databases combine database technology with the technology of object-oriented programming. These databases are focused on objects and data, rather than actions and logic.
An object-oriented database adds the functionality of databases to an object programming language such as Ruby, C++, Java or Python. In an object-oriented database, the data in a single column or row can be grouped and treated as a single object. An object may also refer to the association between an attribute and a database entity. For example, relating the mass of an inventory item to that specific item.
Database management software can be used by database administrators to regulate access to secure databases, including setting user permissions, regulating access credentials and setting up user authentication steps. Beyond that, organizations can invest in modern security solutions like Sumo Logic that help monitor and regulate access to database servers stored in the cloud.
Sumo Logic gives security analysts real-time insight into database server activity, along with artificial intelligence capabilities to support the detection of security threats or anomalies. The ability to troubleshoot database performance while monitoring the system for suspicious usage or unauthorized access makes Sumo Logic an exceptional tool for enhancing database security.
