DML SQL Databases

From the computer point of view, an object-oriented paradigm forces you to use a different logic when to raise a possible model solution; classes, inheritance, encapsulation, are just some of the basic concepts with which we shall familiarise ourselves if we wish to adopt this paradigm as our working tool, hoping that results to develop, store and retrieve data, among others, are positive, at least that is written in theory. The relational model is perhaps as greater complexity, reaching a proper normalization form and establish correct relationships and cardinality which allow us to have an efficient operation in our bdd. It is worth mentioning that there is currently a standard for the management of relational databases, the SQL standard. ste query language has come to give you one even greater this impact relational paradigm and model has made this the most widely used so far by all the developers. Each dbms has an own version of SQL but the essence of language is the same, and it still serves as a unique in its genre and still quite alive tool ahead. The oodb have not lagged behind and it has recently given know a tool equivalent to SQL, OQL which is not computationally complete, however, queries can invoke methods, and inversely the methods written in any programming language may include reference 5. With this language also come ODL and OML which are languages for defining and manipulating data respectively, both DDL and DML SQL equivalents.

Conclusion believe that object-oriented databases still does not have matured enough so they pose a first alternative solution, however the advantages offered are broad, and perhaps not too distant ever to pass to the head in terms of developing databases are concerned, however, the relational data models are still a very good option, even think of improvements to this paradigm that could in the future reaffirm it as the most widely used model of databases. 2 3 4 5 #capIII321 L.I.
