   • Database - What is a good database design for a booking system?

     Top Answer

     Answered Feb 26, 2018 · 1 votes

     I would suggest, first of all, write all the requirements in one table. 1 row is the flat structure of all the requirements. Then start breaking it one by one. That 1 table structure should be having all the required columns. Then follow Normalization concepts of breaking 1 single table into multiple tables.

   • What is a "database entity" and what types of DBMS items are considered entities?

     Top Answer

     Answered Aug 19, 2009 · 15 votes

     In the entity relationship world an entity is something that may exist independently and so there is often a one-to-one relationship between entities and database tables. However, this mapping is an implementation decision: For example, an ER diagram may contain three entities: Triangle, Square and Circle and these could potentially be modelled as a single table: Shape.

     Also note that some database tables may represent relationships between entities.

     That's quite a general question!

     Basically, all types that the database system itself offers, like NUMERIC, VARCHAR etc., or that the programming language of choice offers (int, string etc.) would be considered "atomic" data(base) types.

     Anything that you - based on your program's or business' requirements - build from that, business objects and so forth, are entities.

     Tables, constraints and so forth are database-internal objects needed to store and retrieve data, but those are general not considered "entities". The data stored in your tables, when retrieved and converted into an object, that then is an entity.

     This seems helpful: http://en.wikipedia.org/wiki/Entity-relationship_model

     In a database an entity is a table. The table represents whatever real world concept you are trying to model (person, transaction, event).

     Contraints can represents relationships between entities. These would be foreign keys. They also enforce rules like first_name can not be blank (null). A transaction must have 1 or more items. An event must have a date time.

     Stored Procedures / Packages / Triggers could handle more complex relationships and/or they can handle business rules, just depends on what it's doing.

     I’m not sure about what context you are using business rules in, maybe some kind of check constraint?

   • What is a database connection, technically?

     Top Answer

     Answered Sep 27, 2022 · 9 votes

     Here is a short, but nice socket tutorial.

     You have to distinguish the client and server side. I cannot tell for MySQL, but typically the server side is implemented so, that for a connection, a new thread is processing the requests.

     A connection pool is there to minimize socket opening overhead. Typically, you do not care via which connection (assuming all connected as the same user); you received the result set from database.

     You do not want to consume resources, so you want to be nice and when you are finished you close your connection. I believe every server today ends a connection if there isn't any activity for some time (timeout).
