There are occasions when the addition of a NoSQL database can be beneficial to the efficiency of a system. Hybrid SQL and NoSQL Enterprise Database Systems

#DATABASE DESIGN SOFTWARE#

The core of a solid software application is the database, it must be completely thought out, charted, modeled, and sanity-checked before development begins. We create high-level and detailed technical specification documents that fully describe your application data. The database level should follow and enforce the same data-type requirements as your objects. In a high-level flowchart, the objects that populate your system are stored in persistent memory via your SQL database. Object-oriented model database mapping in Enterprise SystemsĪ well-designed enterprise system will have a system object model that is mirrored in the database design. A good database architect understands the rules of normalization and knows the proper time to apply standards. We ensure your database will be designed properly following best practices and at minimum meet the 3rd normal form. It also ensures data integrity by limiting attributes to sets from child tables. Reaching 3NF ensures that the data is stored as efficiently as possible. An enterprise database should always meet at a minimum the 3NF ( Third Normal Form) of normalization.

The abstraction layer creates a robust topology that allows modification of child attributes without touching parent tables.Įnterprise database design follows the same rules as any normalized relational database. Enterprise Database Table Structureĭatabase normalization reduces redundancy and ensures data integrity across large systems. When you are tying together systems for real-world business applications you need the power of relational SQL. SQL was designed to handle multi-level (wide and deep) data structures and complex relationships. SQL databases allow for complex joins, foreign keys, and grouping of related fields across multiple tables. The records are completely schemaless, so in theory, every record in a NoSQL table could have a unique set of columns. NoSQL databases like DynamoDB and MongoDB do not allow for normalization or foreign keys.

Redis (technically a caching system that follows NoSQL).

Ideal for fast caching, user settings, wide shallow datasets. Ideal for business applications, advanced reporting, and data-mining. They are great for storing user settings and caching, but as they are “schemaless”, they lack the flexibility and power to handle complex data sets. They work well for single-level (very wide and very shallow) data sets. NoSQL databases are designed for high-volume, low complexity, internet applications. Enterprise applications are built on relational database architecture and use Structured Query Language (SQL). Entexture specializes in developing enterprise applications. SQL versus NoSQLĭifferent applications require different technology. You should complete a high-level application flowchart before you start the DB schema design. A complete understanding of how the data is used, how it is acquired, and how it will be used in reporting is an absolute requirement.

Your company data is one of your most valuable assets, make sure to use best practices when you design the database schema. Your table relationships must be clearly defined and isolated. Your tables must be normalized, indexed, and keyed properly. Good database design is the foundation of a stable application.
